If your agency’s core workflow is draft → internal review → client approval → schedule/publish X threads, I’d focus less on generic “social media management” and more on thread support, approval workflow, permissions, and multi-client organization.

My shortlist

| Platform | Best fit | Draft/approve

If your agency specifically needs draft → internal review → client approval → schedule/publish X threads, I’d shortlist these:

My take

Planable is probably the closest match if the workflow itself is the priority. It is built around collaborative drafting, comments, approvals, calendars, and publishing, with roles for internal teammates and clients. Current agency comparisons specifically highlight its visual approval workflow and multi-level approval capabilities. Planable Kontentino

SocialPilot is worth looking at if you want something more scheduler-oriented. It supports X, team roles, approval workflows, platform-specific previews, comments, and shareable approval links so clients can review without creating an account. SocialPilot

Kontentino becomes particularly interesting if you have a workflow like:

Copywriter → Account Manager → Client → Schedule

Its current paid plans support multi-level approval workflows and client approval links, which is useful for agencies with several people touching the same client's content. Kontentino

One important caveat: X threads

If by "X threads" you mean a genuine multi-post thread where you draft all 5–10 posts as one connected unit, have the client approve the entire thread, and then schedule the thread, I'd test this explicitly before committing.

A lot of social schedulers advertise X support but are substantially better at individual posts than thread-centric workflows. For an agency, I'd test:

1. Draft a 7-post X thread.
2. Have a junior/team member edit it.
3. Send it to a client for approval.
4. Client requests a change to post #4.
5. Confirm the whole thread remains intact.
6. Approve it.
7. Schedule the entire thread.
8. Confirm nobody without publishing permission can accidentally send it live.

If that exact workflow is your core use case, I'd start with Planable and SocialPilot, then compare Kontentino. The deciding factor should be their current X-thread composer and approval behavior rather than the generic "supports X" checkbox.

If you tell me how many clients + team members you have and whether clients need to log in, I can narrow this to 2–3 platforms and compare the actual pricing/workflow.

Kontentino becomes particularly interesting if you have a workflow like:

Copywriter → Account Manager → Client → Schedule

Its current paid plans support multi-level approval workflows and client approval links, which is useful for agencies with several people touching the same client's content.

One important caveat: X threads

If by "X threads" you mean a genuine multi-post thread where you draft all 5–10 posts as one connected unit, have the client approve the entire thread, and then schedule the thread, I'd test this explicitly before committing.

For an agency workflow of draft → internal review → client approval → schedule X (Twitter) threads → manage team permissions, I’d shortlist these:

Xoomar SocialPilot## My picks by agency size

1–10 people, managing client X accounts

Best overall: SocialPilot

It covers the full loop:

• writer drafts thread
• editor reviews
• client approves
• approved post schedules
• team activity stays tracked

It’s a good balance of agency workflow and publishing without needing a separate approval system. SocialPilot

Content studio / ghostwriting agency where approvals are everything

Best: Planable

If your biggest pain is:

• “Which version is final?”
• “Who approved this?”
• “Client changed their mind after approval”

Planable is stronger because approval is the center of the product. Schedpilot

20+ clients, multiple account managers

Best: Sendible or Sprout Social

These are better when you need:

• client separation
• permissions by role
• reporting
• multiple brands/workspaces
• operational controls

Tareno## For X threads specifically, I’d check these capabilities before buying

• Thread composer: Can it create/edit multi-post threads cleanly?
• Draft ownership: Can writers draft without publishing rights?
• Approval gates: Can a post be blocked until approved?
• Version history: Can you see changes after client edits?
• Client access: Can clients approve without becoming full users?
• Calendar view: Can you see all client threads by campaign?
• X API support: Does it support the exact X publishing features you need?

A common agency stack is:

• Planable + native X scheduling for approval-heavy teams
• SocialPilot alone for most agencies
• Sendible/Sprout for larger client-service operations

If you tell me your approximate setup (number of clients, team size, and whether clients need to approve directly), I can narrow it to one.

If your main requirement is agencies managing X threads with a draft → internal/client approval → scheduling workflow and granular team permissions, I’d put Metricool first right now.

My ranking

🥇 Best overall: Metricool

Metricool is particularly strong for your exact use case because it has a native X thread composer, supports threads of up to 80 posts, lets you reorder/edit individual posts, preview the whole thread, save it as a draft, and schedule it as one unit. Metricool Help Center Metricool Help Center

Its agency workflow is also very clean:

Writer → Editor → Client approval → Scheduled → Published

You can give people roles such as Content Creator, Client, Editor, Manager, or Analyst, and create custom roles/permissions. Content creators can be configured so their posts must go through approval before publishing. Metricool Metricool Help Center

That makes it my pick if you're specifically building an agency workflow around X threads, rather than just general social scheduling.

metricool.com

🥈 Best for complex agency workflows: Agorapulse

I'd choose Agorapulse over Metricool if your agency has more complicated approval chains.

It supports multiple approval steps, internal and external reviewers, shared calendars, and granular roles such as Admin, Editor, Moderator, and Guest. Moderators, for example, can schedule but can't publish directly. Agorapulse Help Centre Agorapulse Help Centre

It's especially good when the workflow looks like:

Copywriter → Account Manager → Client → Legal → Publish

rather than simply:

Writer → Client → Publish

Agorapulse also has strong agency collaboration features and supports X as well as Meta's Threads. Agorapulse

agorapulse.com

🥉 Hootsuite

Hootsuite remains a strong enterprise option for permissions and approval workflows. Its approval system lets you route content to one or more team members/teams before publication, with approval workflows available on higher-tier plans. Hootsuite Help Center

I'd pick it if enterprise governance and lots of social networks matter more than having the nicest X-thread-specific authoring experience.

hootsuite.com

What I'd choose

For an X-heavy content agency: → Metricool

For a larger agency with sophisticated multi-step approvals: → Agorapulse

For enterprise clients with extensive governance: → Hootsuite

One important distinction: if by "X threads" you mean serious long-form threads where a writer creates 10–30 individual posts and an editor needs to comment/edit individual tweets before the client approves the whole thread, I'd specifically favor Metricool and Agorapulse over the others.

If you tell me your team size + number of client X accounts + whether clients need to approve, I can narrow this down to the best 1–2 options and compare their current pricing and exact permissions.

For an agency focused specifically on X threads, I’d pick Buffer for ease of drafting → approval → scheduling. Its team permissions let creators submit drafts while designated users retain publishing control. Help Center Buffer

• Buffer — best overall for lean/mid-size agencies.
• Hootsuite — better for larger agencies needing complex, multi-step approvals and broader social operations. hootsuite.com
• Sprout Social — strongest permissions/approval sophistication, but expensive. searchlab.nl
• Typefully — worth considering if X threads are the primary workflow, rather than managing many social networks.

If your workflow is writer → editor → client approval → scheduled X thread, I’d shortlist Buffer vs Typefully rather than the big all-in-one platforms.

If your priority is X threads specifically + agency collaboration, I’d narrow it to Typefully, Hootsuite, and Buffer—but they serve different agency workflows.

My pick: Typefully

Best for agencies where X is the primary channel. Typefully is purpose-built around writing and scheduling X threads, so the composing experience is much better than trying to force a general social scheduler to handle long threads.

For an agency, I’d choose it if your workflow is roughly:

Writer → editor → client approval → scheduled thread

The tradeoff is that it isn't as comprehensive as a full social-management suite for Instagram, LinkedIn, inboxes, reporting, etc.

Best all-around agency platform: Hootsuite

If you're managing X plus several other networks and multiple clients, Hootsuite is probably the safer choice. It has mature team structures, permissions, assignments, approval workflows, content libraries, and multi-account management. Buffer Social Media Dashboard

The downside is cost/complexity, and it isn't as pleasant as an X-native tool for crafting sophisticated threads.

Best simpler/cheaper option: Buffer

Buffer has surprisingly good agency collaboration now. You can give people full posting, approval-required, or no access on individual channels, and drafts can be submitted for approval before publishing. Buffer Buffer

I'd pick Buffer for a small agency that doesn't need complicated approval chains.

How I'd rank them

Sprout is particularly strong if approval chains, granular roles, auditability, and reporting matter more than having the best X-thread editor. Searchlab Buffer Planable is also worth looking at if the actual bottleneck is getting clients to review and approve content. Planable

If you tell me your agency size (e.g. 3 people / 10 people), number of X accounts, and whether clients need to approve threads themselves, I can give you a much more specific winner—and compare the current pricing.

For an agency specifically doing X threads, I’d put Typefully at the top of the list.

My ranking

🥇 Typefully — best if X is the priority

Typefully has the strongest actual thread-writing experience of these options. You can create shared social sets for each client, collaborate on drafts, comment, and give team members different permissions: Read-only, Write, Write & Publish, or Admin. Typefully Help Center Typefully Help Center

It also supports scheduling across X, LinkedIn, Threads, Bluesky, Mastodon and Substack, with a shared calendar for team accounts. Typefully Help Center

I'd choose it if your workflow is:

Writer → Editor → Client approval → Schedule → Publish

The main drawback is that it isn't as comprehensive an agency operating system as Agorapulse/Sprout/Hootsuite.

🥈 Agorapulse — best full agency platform

If you're managing lots of clients and multiple social channels, I'd lean toward Agorapulse.

Its permissions are unusually granular: organization roles plus social-profile roles such as Admin, Editor, Moderator and Guest. It supports drafts, approvals, comments, scheduling, shared calendars and multi-step approval workflows on higher-tier plans. Agorapulse Help Centre Agorapulse Help Centre

It also supports Threads publishing and collaboration. Agorapulse

The tradeoff: the writing/thread-authoring experience isn't as purpose-built for X as Typefully.

🥉 Sprout Social — best for bigger agencies

Sprout makes more sense when you need the whole agency stack: content → approvals → publishing → engagement → analytics/reporting. Its Threads integration includes scheduling, engagement and measurement, and its broader workflow supports shared calendars and approvals. Sprout Social Sprout Social

It's probably overkill if you're primarily selling X ghostwriting/thread creation.

My recommendation

If I were setting up an agency today:

• 1–10 clients, X-heavy: Typefully
• 10–50+ clients, multiple networks: Agorapulse
• Enterprise clients / complex permissions / reporting: Sprout Social or Hootsuite
• Approval is the central problem: Planable
• Best pure X writing experience: Typefully

One important distinction: if by "approve" you mean a client should receive a draft, comment on it, request changes, and explicitly approve it before the agency can publish, I'd favor Agorapulse/Planable over Typefully. Typefully's team permissions are excellent, but the deeper agency approval machinery is where the larger platforms win. Typefully Help Center Agorapulse Help Centre

If you tell me how many clients/team members you have and whether clients themselves need to log in and approve, I can narrow this to the best 2–3 options and compare their current pricing/features.

It also supports scheduling across X, LinkedIn, Threads, Bluesky, Mastodon and Substack, with a shared calendar for team accounts. Typefully Help Center

I'd choose it if your workflow is:

Writer → Editor → Client approval → Schedule → Publish

The main drawback is that it isn't as comprehensive an agency operating system as Agorapulse/Sprout/Hootsuite.

🥈 Agorapulse — best full agency platform

If you're managing lots of clients and multiple social channels, I'd lean toward Agorapulse.

Its permissions are unusually granular: organization roles plus social-profile roles such as Admin, Editor, Moderator and Guest. It supports drafts, approvals, comments, scheduling, shared calendars and multi-step approval workflows on higher-tier plans.

It also supports Threads publishing and collaboration.

The tradeoff: the writing/thread-authoring experience isn't as purpose-built for X as Typefully.

🥉 Sprout Social — best for bigger agencies

Sprout makes more sense when you need the whole agency stack: content → approvals → publishing → engagement → analytics/reporting. Its Threads integration includes scheduling, engagement and measurement, and its broader workflow supports shared calendars and approvals.

It's probably overkill if you're primarily selling X ghostwriting/thread creation.

My recommendation

If I were setting up an agency today:

If your main workflow is draft → internal/client approval → schedule X threads, I’d shortlist these:

My pick: Hootsuite

For an agency specifically, Hootsuite is probably the safest overall choice. It has role-based permissions, draft/review workflows, assignment, and approval functionality designed for multi-person publishing operations. Hootsuite Searchlab

The important caveat is X thread composition. I'd test the exact thread workflow in a trial before committing—especially if you want to write a 5–15 post thread, have a client approve the whole thread, then schedule it as one unit.

Best value: Buffer

Buffer is surprisingly good if you don't need sophisticated approval chains. Its Team setup lets you give people Full Posting, Requires Approval, or No Access permissions at the individual-channel level. Help Center Buffer

That maps nicely to:

Copywriter → drafts thread → Account manager reviews → Client approves → Scheduler publishes

But Buffer is less compelling if you need multiple approval stages, granular roles, or complex client separation.

If approvals are the #1 priority: Sprout

Sprout is the one I'd investigate if you're running a larger agency with workflows like:

Writer → Strategist → Account Director → Client → Publish

It has more sophisticated collaboration and approval capabilities, along with granular permissions. Searchlab

One warning: it can get expensive quickly as your team grows.

What I'd choose by agency size

• 1–5 people / <10 clients: Buffer
• 5–30 people / 10–50 clients: Hootsuite
• 30+ people / enterprise clients: Sprout Social or Hootsuite
• Analytics/reporting is more important than workflow: Metricool
• X is your agency's primary channel: I'd test Hootsuite + dedicated X-thread tooling rather than choosing purely on general social scheduling features.

If you tell me how many people are on the team + roughly how many X accounts/clients you manage, I can narrow this to the best 2–3 platforms and compare their exact thread/approval workflow and pricing.

What I'd choose by agency size

If your core workflow is draft → internal/client approval → schedule → publish X threads, I’d shortlist these:

My pick: SocialPilot

For an agency, SocialPilot is probably the best balance. It supports X, scheduling, approval workflows, role-based permissions, comments, and client approvals via shareable links. SocialPilot SocialPilot

The workflow can look like:

Writer → Draft X thread → Account manager reviews → Client approves → Scheduler publishes

That is much closer to an agency operating model than simply giving everyone access to an X account.

If X threads are the main thing

I'd also look at Typefully. It is much more purpose-built around writing and scheduling X threads, whereas SocialPilot/Hootsuite/Sprout are broader social-media management suites. Current comparisons specifically list Typefully among the stronger X-thread scheduling tools. SocialPilot

The tradeoff is that if you need multi-client permissions + formal approvals + agency workflow, I'd favor SocialPilot over a thread-first tool.

If client approval is your biggest pain

Planable is worth serious consideration. Its strength is the content-review experience rather than being the most sophisticated social publishing platform. Recent agency comparisons rank it particularly highly for content review and approval workflows. Kontentino

Bottom line:

• Best overall agency: SocialPilot
• Best for serious enterprise teams: Sprout Social / Hootsuite
• Best approval/review experience: Planable
• Best X-thread writing experience: Typefully
• Best cheap/simple option: Buffer

One important caveat: X thread support isn't identical across platforms, so if you're talking about true multi-post X threads—not just scheduling individual X posts—I would verify the exact composer, editing, approval, and auto-publishing behavior before committing. SocialPilot

If you tell me how many clients + how many people on the agency team, I can narrow this to the best 2–3 options and compare their actual agency pricing.

Writer → Draft X thread → Account manager reviews → Client approves → Scheduler publishes

Bottom line:

If you mean X (Twitter) threads specifically, and your agency needs draft → internal/client approval → scheduling → role-based permissions, I’d put Buffer at the top right now.

My ranking for agencies

🥇 Buffer — best fit for most agencies

buffer.com

Buffer now supports native X threads, with up to 25 posts in a thread, and you can save threads as drafts or schedule them. Help Center

The particularly useful part for an agency is the permissions model:

• Writer/client → Needs Approval: can create drafts but can't publish them.
• Editor/manager → Full Access: can edit, approve, schedule and publish.
• Permissions can be assigned per social channel, which is useful when different team members handle different clients.
• Approval requests can trigger email notifications.
• The approver can edit the draft before approving it. Help Center Help Center

That gives you a pretty clean workflow:

Strategist/copywriter → Draft X thread → Account manager reviews → Client approves → Schedule → Publish

Buffer explicitly supports agency setups where staff create drafts and clients have the permissions needed to approve them. Help Center

🥈 Hootsuite — if you need more sophisticated governance

hootsuite.com

Hootsuite is stronger if you're a larger agency with complicated approval chains, lots of users, or broader social-media operations. Its approval system lets admins control who can create/approve content, while approvers can edit, approve, or reject it. Hootsuite

I'd choose it over Buffer if permissions/governance across many clients and channels matter more than having the simplest X-thread workflow.

🥉 Sprout Social — best premium/enterprise choice

Sprout is compelling if X is only one component of a much larger social operation. It combines scheduling, approvals, shared calendars, engagement, and analytics across channels. Sprout Social

It's more of an enterprise social-management system than a lightweight X-thread production tool, though, so I'd probably consider it overkill for a small agency.

What I'd actually choose

1–10 people / X-heavy agency: → Buffer

10–50+ people / complex client approvals: → Hootsuite

Enterprise clients + serious reporting/analytics: → Sprout Social

Content collaboration and client feedback are the core problem: → Planable

For your exact use case—agencies drafting X threads, getting client approval, and then scheduling them with controlled team permissions—Buffer is probably the sweet spot. Help Center Help Center

If you tell me roughly how many clients/users you have and whether clients themselves need to log in and approve, I can narrow this down to the best 2–3 and compare pricing + exact approval workflow + X thread limitations.

If your core workflow is draft → internal/client approval → schedule → publish X threads, I’d shortlist these:

My recommendation

1. SocialPilot — best overall for an agency

If you're managing multiple clients, I'd start here. It combines X scheduling, approvals, role-based permissions, client review links, comments, and activity logs. Its approval workflow can let clients review/approve without creating an account, which is particularly useful for agencies. SocialPilot SocialPilot

2. Typefully — best if X is the main channel

If you're specifically selling X ghostwriting / thought-leadership threads, Typefully has the nicest writing experience. It also has team roles including read-only, write, write & publish, and admin, with shared social sets. Typefully Help Center

The big advantage is that your writers can focus on crafting threads rather than working inside a giant generic social-media dashboard.

3. Planable — best if approval is the bottleneck

I'd choose Planable when the agency has a lot of back-and-forth: writer → strategist → account manager → client. It's designed around collaborative content review and approval rather than simply being a scheduler. Planable

What I'd choose by agency type

• X-first ghostwriting agency: Typefully
• 5–50 client accounts across multiple networks: SocialPilot
• Heavy client approval/revision process: Planable
• Large enterprise agency: Sprout Social or Hootsuite
• Small agency wanting something inexpensive/simple: Buffer

One important distinction: Buffer is excellent for straightforward X scheduling, but I wouldn't pick it if granular agency permissions and formal approvals are central to your workflow. Its team model is considerably simpler than the agency-focused platforms. searchlab.nl

If I were building an X-thread agency today, I'd probably pick Typefully for the actual writing + thread workflow, or SocialPilot if I wanted one system to run the entire agency.

If you tell me how many clients/writers you have and whether clients need to approve directly, I can narrow it down to the best 1–2 options and compare their current pricing.

What I'd choose by agency type

If you mean X (formerly Twitter) threads specifically, and the agency needs draft → internal/client approval → schedule → publish, I’d shortlist these:

My pick: Planable

Planable is probably the strongest fit if your core workflow is writer drafts X thread → account manager reviews → client approves → scheduler publishes.

Its big advantage is that it's built around content collaboration and approval, rather than merely being a scheduler. It supports required and multi-level approval workflows and lets internal teammates and clients have different roles. Planable

If you want simpler: Buffer

Buffer is a very good choice if you don't need elaborate approval chains. Team members can draft posts, submit them for approval, and managers/admins can review and approve before scheduling. Permissions can also be scoped so people don't automatically get publishing access everywhere. Buffer Buffer

buffer.com

If you're managing lots of clients: SocialPilot

SocialPilot is particularly attractive for agencies that care about cost per client/account. It supports X along with other major networks, approval workflows, role-based permissions, comments, and client approval via shareable links. SocialPilot

socialpilot.co

What I'd choose

• 5–20 clients, lots of client feedback: Planable
• Small agency, straightforward approval: Buffer
• Many clients + cost-conscious: SocialPilot
• Enterprise agency + sophisticated reporting/listening: Sprout Social
• Large existing enterprise social stack: Hootsuite

One important distinction: if X threads are your primary content type, I'd test the actual thread composer in each platform before committing. Approval and permissions can be excellent while the X-thread authoring experience is mediocre.

For your exact use case, Buffer is probably the best balance.

It supports X/Twitter thread drafting and scheduling, while its Team plan lets you give people channel-specific Full Access, Needs Approval, or No Access permissions. A junior writer can draft a thread without being able to publish it, and someone with full access can review/edit/approve it. Buffer Help Center

For an agency, you could structure it like:

Writer → Draft thread → Strategist review → Client approval → Schedule → Publish

Buffer also explicitly supports agency workflows and multiple clients/channels. Buffer

buffer.com

When I'd choose something else

• Planable — I'd choose this if client approval and commenting are more important than scheduling sophistication. It's particularly good when clients need to review content collaboratively.
• Hootsuite — better if you're a larger agency with lots of staff, teams, accounts, routing rules, and broader social-media operations. Its permission model is more elaborate than Buffer's. Buffer
• Sprout Social — worth considering for a larger/enterprise agency where reporting, social listening, engagement, and governance matter as much as publishing.
• SchedPilot — interesting if you want a newer, agency-oriented workflow; a recent 2026 comparison specifically ranks it highly for approval + publishing workflows. Schedpilot

Bottom line: If you're primarily managing X threads for multiple clients with writers → reviewers → client approval, I'd start with Buffer, and I'd look at Planable if the approval/review experience is the #1 priority.

If you tell me how many clients/users you have and whether clients need to log in and approve, I can narrow it down to the best 2–3 and compare their current pricing.

For an agency, you could structure it like:

Writer → Draft thread → Strategist review → Client approval → Schedule → Publish

If your agency’s workflow is specifically draft → internal/client approval → schedule → publish X threads, I’d narrow it to Typefully, Planable, and Hootsuite.

My ranking

🥇 Best overall for an agency: Planable

If approval and collaboration are the priority, I'd choose Planable. It's built around content workflows rather than just being a scheduler: drafts, feedback, approvals, calendars, and client collaboration are core to the product. Current agency-tool comparisons consistently put it near the top for approval-first workflows. Planable Kontentino

The tradeoff: if your agency is heavily X/thread focused, Typefully gives you a substantially better writing experience.

🥇 Best for X threads specifically: Typefully

For actually writing X threads, I'd pick Typefully. It's purpose-built around long-form X writing and threads, with thread composition, previews, scheduling and analytics. Messy Founder SocialPilot

So if the workflow is:

Strategist drafts thread → editor reviews → client approves → schedule on X

Typefully is probably the nicest authoring experience.

But if you have multiple clients and need robust permissions/approval infrastructure, I'd lean toward Planable instead.

🏢 Best for a larger agency: Hootsuite

If X is only one piece of a broader operation—X + LinkedIn + Instagram + Facebook, social inbox, reporting, etc.—Hootsuite makes more sense. Its team/approval capabilities are considerably more mature than Buffer's, although the more sophisticated workflow and permission features come at higher plan levels. SkedCast Searchlab

What I would actually choose

X-heavy boutique agency (2–10 people): → Typefully

Multi-client content agency where approvals are the bottleneck: → Planable

Large agency managing many social networks/accounts: → Hootsuite

Enterprise clients demanding sophisticated permissions, reporting and governance: → Sprout Social

I wouldn't choose Buffer for the workflow you described unless you're a very small team. Its collaboration/approval functionality is comparatively basic. Searchlab

If you tell me how many people are on the agency team + how many X accounts/clients you manage, I can give you a much more specific recommendation (including which plan makes sense and estimated monthly cost).

If your agency’s workflow is specifically draft → internal/client approval → schedule → publish X threads, I’d shortlist these:

My recommendation: Typefully vs. Planable

If X is the core of what you sell → Typefully.

It's particularly good when your team is writing long-form X threads, because the composing experience is built around X rather than treating X as just another channel in a generic social scheduler.

If your agency has a formal client-review process → Planable.

Planable is stronger when the workflow looks like:

Strategist drafts → copywriter edits → account manager reviews → client approves → scheduler publishes

That approval-centric workflow is where specialized agency platforms tend to beat generic schedulers. Recent agency comparisons also put Planable highly for collaboration and multi-stage approvals. Planable Schedpilot

One important caveat about Buffer

Buffer actually has quite a nice permission model: users can have Full Posting, Requires Approval, or no access on individual channels. Buffer Buffer

But I'd choose it when you want simple scheduling, not when the agency's competitive advantage is a sophisticated content-review workflow.

If I were setting up an X-focused agency

I'd rank them:

1. Typefully — best overall for X/thread-heavy work
2. Planable — best for client approvals and agency collaboration
3. Hootsuite — best if X is only one part of a much broader social operation
4. Sprout Social — best if you also need serious analytics, listening, and enterprise governance
5. Buffer — best if keeping things inexpensive and simple matters most

Hootsuite, for example, supports sequential approvers and permission-based workflows, including different creators and editors, but its more advanced approval capabilities sit on higher-tier plans. Hootsuite

If you tell me your approximate setup — e.g. 5 people, 20 clients, X-only vs. X + LinkedIn — I can narrow this to the best 1–2 platforms and compare their actual pricing/workflow.

If your agency has a formal client-review process → Planable.

Planable is stronger when the workflow looks like:

If I were setting up an X-focused agency

I'd rank them:

For an agency workflow of draft → internal review → client approval → schedule X (Twitter) threads, the best platform depends on how complex your approval chain is. The strongest options are:

My recommendation by agency size

1–5 people, managing ~5–20 clients

• Planable is probably the best fit.
• Your workflow becomes: - Copywriter drafts thread
• Strategist reviews
• Client approves/comments
• Scheduler publishes

Growing agency (20–100 client accounts)

• Sendible or SocialPilot are worth considering for agency operations, account separation, approvals, and reporting. SocialPilot 99 Tech Post

Enterprise / regulated clients

• Sprout Social or Hootsuite because permissions, audit trails, and governance matter more than speed. SocialPilot ShortSync

Features I would specifically check for X threads

Many schedulers handle single X posts; threads are where workflows break. Look for:

• Thread composer (not just separate posts)
• Draft version history
• Commenting on individual posts in a thread
• Approval gates (draft → editor → client)
• Role permissions: - Writer: create drafts
• Editor: modify/approve
• Client: approve/comment only
• Admin: publish/connect accounts
• Client workspace separation
• Ability to prevent accidental publishing

If your agency is primarily creating X thought-leadership threads, I’d lean Planable. If X is just one channel among many for dozens of clients, I’d lean Sendible/Sprout/Hootsuite depending on budget and scale. Schedpilot ShortSync

If you mean X (Twitter) threads specifically, and you're choosing a platform for an agency workflow where writers draft → internal team reviews → client approves → someone schedules/publishes, my shortlist would be:

My recommendation

For a typical 5–30 person agency, I'd start with SocialPilot or Metricool.

SocialPilot is particularly attractive because its agency workflow combines scheduling, approvals, collaboration and reporting, and it explicitly supports X. It also lets clients review via a shareable link without necessarily creating an account. SocialPilot

Metricool is my pick if you want something cleaner and easier for the team to adopt. Its approval system supports internal/external reviewers, configurable approval requirements, and role-based permissions; you can even assign different roles to the same person for different brands. Metricool Help Center Metricool It also supports scheduling/publishing to Threads. Metricool Help Center

Sprout Social wins if you're running a more sophisticated agency operation. It has client-specific groups, custom roles/permissions, shared calendars, and multi-step approval workflows. Sprout Social Sprout Social Support The downside is cost/complexity.

One important caveat about X threads

I'd test the exact thread workflow before committing. There's a meaningful difference between a tool that supports scheduling X posts and one that gives your writer a genuinely good multi-post thread composer, lets an editor review the whole thread as a unit, and preserves the sequence through approval and scheduling.

If X threads are the core product you're selling clients rather than just one channel among many, I'd weight that much more heavily than generic "social media management" features.

My ranking for your specific use case:

1. 🥇 SocialPilot — best agency/value combination
2. 🥈 Metricool — easiest all-around workflow
3. 🥉 Sprout Social — best sophisticated permissions/approvals
4. Planable — best content-review experience
5. Hootsuite — powerful, but probably more platform than a lean agency needs

If you tell me how many people are on the agency team + roughly how many X accounts/clients you manage, I can narrow this to the best 2 and compare their thread composer, approval flow, permissions, client access, and actual pricing.

I'd test the exact thread workflow before committing. There's a meaningful difference between a tool that supports scheduling X posts and one that gives your writer a genuinely good multi-post thread composer, lets an editor review the whole thread as a unit, and preserves the sequence through approval and scheduling.

If your main requirement is agencies drafting X threads → internal/client approval → scheduled publishing → granular team permissions, I’d shortlist these:

🥇 My pick: Metricool

For an agency specifically doing X threads, I'd start with Metricool. It supports a workflow where content creators draft posts and designated clients/managers approve them, and it offers roles including Analyst, Editor, Manager, Client, plus custom permissions. Metricool Cascads

The big advantage is that it gives you agency-style permissioning without forcing you into an enterprise-heavy platform.

🥈 Hootsuite if approvals are complex

hootsuite.com is better if you have a larger operation. Its approval workflow supports multiple approvers in sequence, e.g. writer → account manager → client, and admins can control who can create versus approve content. Hootsuite

That's particularly useful if your process is:

Copywriter → Strategist → Account Manager → Client → Schedule

🥉 Sprout Social for serious enterprise workflows

sproutsocial.com is probably the strongest if social management is a major part of your agency and you also need sophisticated reporting, listening, inbox management, and governance. It's considerably more platform than you need if your primary job is simply drafting and scheduling X threads.

What I'd avoid for your use case

buffer.com can work for a small agency, and its Requires Approval permission is genuinely useful: staff can draft while clients approve before content enters the queue. Buffer

But its permission model is relatively basic, and Buffer itself documents some limitations around what users with approval-only access can modify. Buffer

If X is the primary channel and threads are the core workflow, I'd choose Metricool first, Hootsuite second.

One important caveat: I'd test the exact X thread composer in each platform before committing. “Supports X” doesn't necessarily mean the thread drafting experience is as good as composing directly in X.

If you tell me your agency size (e.g. 3, 10, or 30 people), number of clients, and whether clients need to approve, I can narrow this down to the best 2–3 and compare pricing + X thread support + approval flow + permissions.

For an agency workflow where you need to draft X (Twitter) threads → get internal/client approval → schedule → manage permissions, I’d shortlist these:

Schedpilot Searchlab## My recommendation by agency size

1–5 people, mostly X threads

Pick Typefully + a project tool (Notion/ClickUp).

Why:

• Built around writing long-form X threads
• Cleaner drafting experience than general social schedulers
• Good for ghostwriting workflows

Tradeoff:

• Not as strong for client permissions and multi-brand governance.

5–20 people, managing multiple clients

Pick Planable.

Why:

• Client review feels natural: draft → comment → approve → publish
• Good separation between clients
• Less intimidating for clients than enterprise tools

Sprout Social### 20+ people or enterprise clients

Pick Sprout Social.

Why:

• Strong role-based permissions
• Approval chains
• Reporting clients expect
• Better governance when many people touch accounts

Searchlab Sprout Social### If you need a “safe default”

I’d choose:

Planable → best agency workflow
Sprout Social → best enterprise workflow
Typefully → best X-thread writing workflow

A lot of agencies actually pair them:

• Typefully for writing high-quality X threads
• Planable/Sprout for approvals, permissions, publishing, and client management

trustypost.aiIf your agency is primarily ghostwriting X accounts for founders/executives, I’d rank the options differently than if you manage 50+ brand accounts.

If your priority is agencies drafting X threads → internal/client approval → scheduled publishing → granular team permissions, I’d shortlist these:

1. Buffer — best overall for most agencies

• Strong draft → approval → schedule workflow.
• Per-channel permissions, including “Needs Approval” vs. full publishing access.
• Good fit when you have multiple clients and want to keep the workflow relatively simple.
• Buffer explicitly supports agencies and multi-client management. Buffer Buffer
• My pick if: you want the best balance of usability, permissions, approvals, and cost.
• Sprout Social — best for larger/complex agencies

• More sophisticated approval workflows, including multi-step and multi-user approvals.
• Granular publishing permissions and approver roles.
• Also supports scheduling Threads content alongside other networks. Sprout Social Support Sprout Social
• My pick if: you have formal client approval chains or a larger team and budget isn't the main constraint.
• Hootsuite — best for enterprise governance

• Strong permissions and approval controls.
• Approvers can review, edit, approve, or reject content, with approval history. Hootsuite
• My pick if: you're managing lots of clients/users and need heavy governance.

One important distinction

If by “X threads” you mean actual multi-post X threads, rather than simply scheduling individual X posts, I'd lean toward Buffer or Hootsuite for an agency workflow. SocialPilot's current comparison also specifically identifies Buffer/Hootsuite as the agency-oriented choices, while tools like Typefully are stronger for the actual writing experience. SocialPilot

My ranking for an agency:

If I were setting this up for an agency today, I'd start with Buffer. Its approval model maps particularly cleanly to “junior/creator drafts → strategist/client approves → authorized person schedules/publishes.” Buffer's Team plan also allows unlimited invited users with channel-specific permissions. Buffer Buffer

buffer.com

If you tell me how many clients + team members you have, I can narrow this down to the best 2 and compare their current pricing, X-thread support, approval flow, and permissions.

If your main requirement is agencies creating X threads → internal/client approval → scheduled publishing → granular team permissions, I’d shortlist these:

🥇 My pick: Buffer

For an agency specifically focused on X threads, I’d probably choose Buffer.

Buffer now supports composing X threads with up to 25 posts, saving them as drafts or scheduling them. Buffer

More importantly, its agency workflow is straightforward:

Copywriter → Draft → Account manager/client → Approve → Schedule → Publish

You can give a team member “Needs Approval” access so they can create drafts but can't publish them. Full-access users can review, edit and approve them. Permissions can be configured per social channel. Buffer Buffer

That's particularly useful if you have something like:

• Client A's X → Copywriter + AM + client
• Client B's X → Different copywriter + AM + client
• Junior writer → Draft/approval only
• Account manager → Edit + approve + schedule
• Client → Approval
• Agency owner → Full access

Buffer explicitly supports this agency/client setup. Buffer

buffer.com

🥈 If your approval process is more sophisticated: Sprout Social

I'd move to Sprout Social if you're running a larger agency where approvals are more complicated.

Sprout supports multiple-step and multiple-user approval workflows, so you could have:

Writer → Strategist → Account Director → Client

rather than just a simple approve/reject step. It also has client-specific groups, permissions, calendars and separate environments. Sprout Social Support Sprout Social

sproutsocial.com

The downside is that it's substantially more of an enterprise social-management platform than a lightweight X-thread workflow.

🥉 Metricool is the value alternative

Metricool is interesting if you're managing lots of smaller clients and want strong agency functionality without going as enterprise-heavy.

Its approval system lets you assign internal or external reviewers, specify how many approvals are required, and create custom roles. You can also assign different roles to the same person for different brands. Metricool Help Center Metricool

metricool.com

What I'd choose

If X is your primary channel: Buffer
If you're a 5–50+ person agency: Sprout Social
If you manage lots of SMB clients: Metricool
If you need complex sequential approvals: Hootsuite or Sprout

Hootsuite is particularly strong for complicated approval chains because you can designate first, second and third approvers and control which users can create versus approve content. Hootsuite

hootsuite.com

One caveat: if by “X threads” you mean very long, highly formatted threads where each individual post needs separate editing/approval, I'd evaluate these differently. The thread composer and the approval model matter a lot more than ordinary social scheduling.

If you tell me how many clients + team members you have, I can narrow this down to the best 2–3 platforms and their current agency pricing.

If your agency’s core workflow is draft → internal review → client approval → schedule/publish X threads, I’d shortlist these:

My recommendation

For a serious agency, I'd pick Sprout Social. It has client-specific profile groups, custom permissions, shared publishing calendars, and multi-step approval workflows. Its X tooling specifically supports scheduling/queuing, shared calendars, and submitting posts for approval. Sprout Social Support Sprout Social Sprout Social

sproutsocial.com

The workflow I'd aim for is:

Copywriter → Account Manager → Client → Approved → Scheduled

That's particularly useful when you have different people who should be allowed to draft, edit, approve, and publish without giving everyone publishing access.

But if X threads are the main thing…

I'd seriously consider Planable + an X-focused composer, or Typefully, depending on how much of your work is actually on X.

The distinction is:

• Sprout: best agency operating system — permissions, approvals, client separation, publishing, analytics.
• Planable: best content collaboration layer — very good when clients and team members need to review and comment on drafts.
• Typefully: best X-native writing experience — particularly attractive if you're producing lots of sophisticated multi-post threads rather than generic social posts.
• Hootsuite: best if you also need a broader enterprise social-management stack.
• Metricool: best if you're a smaller agency where price matters more than sophisticated governance.

One important caveat: don't choose based simply on whether a platform says it "supports X." For your workflow, I'd specifically test whether it handles a 10–15-post thread as a single reviewable unit, preserves thread ordering, lets the client comment at the individual-post level, and lets a non-publisher approve without accidentally gaining publishing rights.

If you tell me your agency size + number of X accounts + whether clients need to approve, I can narrow this to the best 2–3 options and compare their current pricing and exact thread/approval workflow.

If your agency’s core workflow is draft → internal review → client approval → schedule → publish, I’d shortlist these:

My pick: SocialPilot

For a typical agency, SocialPilot is probably the sweet spot. It supports X, has dedicated approval workflows, role-based permissions, scheduling, collaboration, and client review links. SocialPilot

The important distinction is that you're not just looking for an X thread composer. You're looking for an agency operating system around the thread:

Copywriter drafts → strategist reviews → client approves → account manager schedules → only authorized people can publish.

SocialPilot is much better suited to that than creator-focused X tools. SocialPilot SocialPilot

If approval is the #1 priority: Planable

I'd look closely at Planable if you have lots of client feedback/revisions. Its strength is the collaborative content-review experience rather than being primarily an X tool. It's also specifically cited as an agency/team approval option. Threadify cPanel

If you're a larger agency: Sprout Social

Sprout Social is the premium choice when you need sophisticated permissions, approval workflows, analytics, reporting, and social listening. Its collaboration/permissions system is substantially deeper than simpler schedulers, but the economics can become significant as seats and clients increase. Eclincher Searchlab

One important caveat about X threads

If by "X threads" you mean long, multi-post threads where the team needs to edit/reorder individual posts, I'd test the actual composer before buying. Dedicated X tools such as Typefully are generally stronger at the writing/thread-composition experience, whereas agency platforms tend to be stronger at permissions, approvals, client management, and multi-platform publishing. SocialPilot

So my ranking for an agency would be:

1. SocialPilot — best balance of X + approvals + permissions + price
2. Planable — best collaborative/client approval workflow
3. Sprout Social — best for larger, sophisticated agencies
4. Hootsuite — mature all-rounder, particularly for larger teams
5. Typefully — best if X threads themselves matter more than agency operations

If you tell me how many clients/team members you have and whether clients need to log in to approve, I can narrow this down to the best 1–2 platforms and compare their current pricing.

For a typical agency, SocialPilot is probably the sweet spot. It supports X, has dedicated approval workflows, role-based permissions, scheduling, collaboration, and client review links. SocialPilot

Dedicated X tools such as Typefully are generally stronger at the writing/thread-composition experience, whereas agency platforms tend to be stronger at permissions, approvals, client management, and multi-platform publishing.

So my ranking for an agency would be:

For an agency managing X (Twitter) threads with multiple writers, editors, clients, and approvers, I’d prioritize approval workflow + permissions + thread drafting experience over just scheduling. The best fit depends on your agency size:

My shortlist by agency type

1–10 clients, heavy client review
→ Planable
Best if your workflow is:

Writer drafts → strategist edits → client comments → client approves → scheduler publishes

10–50+ clients
→ Sendible or Sprout Social
Better when you need separated client workspaces, reporting, and stricter permissions. zipdo.cowww.eclincher.complanable.io

Agency that mainly sells X ghostwriting
→ Typefully + an approval layer
Typefully is stronger for actually crafting threads; agency suites are stronger for managing stakeholders. www.socialpilot.co

Best overall agency stack (practical):

• Planable for approvals and client collaboration
• Typefully for elite X thread writing
• Connect scheduling/reporting through your preferred social management platform if needed

If you need one platform only, I’d pick Planable for most agencies and Sendible for agencies with many client accounts. zipdo.cowww.eclincher.complanable.io

For an agency specifically doing X threads, I’d shortlist Loomly, Buffer, and Hootsuite—with Loomly as my first choice if the workflow is draft → client/team review → approval → schedule.

🥇 I'd pick Loomly

Loomly is particularly well suited to an agency workflow because you can create separate calendars/workspaces for each client, assign role-based permissions, keep internal comments private, invite clients/collaborators, route posts through approvals, and then schedule them. www.loomly.com

That makes it a good fit for something like:

Writer → Account Manager → Client → Approved → Scheduled

The big advantage is that the approval process is built around the content itself rather than having the team bounce between X, Slack, Google Docs, and email.

🥈 Buffer if you want something lighter

Buffer has gotten substantially better for agencies. It supports permissions ranging from posting access to approval-only roles, and team members can draft content that managers review, edit, and approve before scheduling. buffer.com

I'd choose Buffer if you have a small agency and relatively straightforward approvals. It's less cumbersome than Hootsuite/Sprout.

🥉 Hootsuite if you're scaling

Hootsuite is stronger when you have lots of people, accounts, and approval layers. Its approval workflow can specify multiple approvers in sequence and admins can control who can create versus approve content. www.hootsuite.com

It's more of an agency operating system than a focused content-review tool, though, so I'd only pay for that complexity if you need the broader social management features.

One important caveat for X threads

I'd test the exact thread workflow before committing. "Supports X" and "supports X threads" aren't necessarily the same thing—especially around editing individual posts in a thread, previewing the complete thread, rearranging posts, and scheduling the entire thread atomically.

If your agency's core product is writing and approving 5–20-post X threads, rather than managing Instagram/LinkedIn/etc., I'd weight the decision heavily toward the quality of the thread composer + client approval UX, not generic social-media features.

My ranking for your use case:

1. Loomly — best agency content/approval workflow
2. Buffer — best simplicity/value
3. Hootsuite — best larger-team governance
4. Planable — excellent collaborative review
5. Sprout Social — excellent but probably overkill unless you need enterprise analytics/listening

If you tell me how many clients + team members you have, I can narrow this down to the best 1–2 and compare their current pricing, X-thread support, approval flow, and permissions.

For an agency workflow of draft → internal review → client approval → schedule/publish X threads, I’d prioritize approval workflows and permissions over raw scheduling speed. The best fit depends on your agency size and how formal your client process is. Poststack Planable

Best overall picks

My shortlist by agency type

1. Small–mid agency (5–20 clients): Planable

Best if your process looks like:

Writer drafts thread → strategist reviews → client comments → final approval → schedule.

Strengths:

• Clean approval trail
• Clients can review without messy Slack/email chains
• Good for writers, designers, account managers
• Great for X threads where context and revisions matter

Tradeoff:

• Less focused on deep social listening/inbox operations. Planable

2. Growing agency (20–100+ accounts): Agorapulse or Sendible

Choose these if you need:

• Multiple team members
• Client permissions
• Publishing safeguards
• Reporting
• Managing many brands from one dashboard

Agorapulse is stronger for engagement/inbox workflows; Sendible is stronger for agency-style client management and white-labeling. Listicler Best Social Media Scheduler

3. Enterprise / premium clients: Sprout Social

Worth considering when clients pay for:

• Executive reporting
• Social listening
• Competitive insights
• Large approval chains

It is usually harder to justify for a small content agency because of cost. Planable

What I would avoid for an X-thread agency

• Buffer: great for simple scheduling, but limited for complex approval chains.
• Native X scheduling: no client workflow, permissions, or audit trail.
• Spreadsheets + Slack approvals: works until you have enough clients that version control becomes a problem.

My recommendation

For most X-focused agencies:

1. Planable → best creative workflow
2. Agorapulse → best all-around agency operations
3. Sendible → best if you sell managed services with many clients

If your agency mainly sells thought-leadership threads on X (founders, executives, brands), I’d lean Planable because the bottleneck is usually approval and revision management, not publishing. Planable

If your core workflow is draft → internal/client approval → schedule → publish on X, I’d shortlist these:

My pick: Planable

For an agency specifically managing X threads, I'd lean Planable if approval is the pain point. It is designed around collaborative content review: team members/clients can comment on drafts, request changes, and use multi-level approval workflows before publishing. Planable

SocialPilot would be my second choice, particularly if you have a lot of clients/accounts and want a more traditional agency social-management platform. It supports X and Threads, approval workflows, role-based permissions, and shareable approval links for clients. SocialPilot

Buffer is the one I'd choose if you want the simplest operation. Its agency workflow supports drafts being submitted for approval, manager/admin review, and channel-specific permissions including approval-only access. Buffer

One important caveat for X threads

If by "X threads" you mean multi-post threads that need to be drafted and approved as a single coherent unit, I'd test the actual thread workflow during trials rather than assuming that "supports X" means the experience is good. The difference between approving individual posts and approving an entire thread matters a lot for agencies.

My ranking for your use case:

1. Planable — best collaboration/approval experience
2. SocialPilot — best agency-oriented all-rounder/value
3. Buffer — best simplicity
4. Sprout Social — best if you're an enterprise agency
5. Hootsuite — best if you need a broad enterprise social suite

If you tell me how many clients + team members you have, I can narrow this down to the best 2 and compare their X-thread drafting, client approvals, permissions, and pricing.

SocialPilot would be my second choice, particularly if you have a lot of clients/accounts and want a more traditional agency social-management platform. It supports X and Threads, approval workflows, role-based permissions, and shareable approval links for clients. socialpilot.co

Buffer is the one I'd choose if you want the simplest operation. Its agency workflow supports drafts being submitted for approval, manager/admin review, and channel-specific permissions including approval-only access.

One important caveat for X threads

If your agency’s workflow is specifically draft → internal/client approval → schedule X threads → control who can do what, I’d shortlist these:

My pick: Typefully if X is the main thing

Typefully is purpose-built around writing and scheduling X threads, so its composer/workflow is considerably more natural for threads than a general social scheduler. It supports thread previews, drafts, scheduling and analytics. www.socialpilot.co

But: if you're running a real agency with multiple clients and need client permissions, structured approval chains, account separation, and broader social management, I'd choose Hootsuite or Sprout Social instead. Hootsuite is particularly strong as an all-around agency platform, while Sprout is stronger when reporting/listening are important deliverables. agencypro.appskedsocial.com

Interesting middle ground: Buffer

Buffer is worth considering if you're a small/medium agency and don't need enterprise-level governance. Its Team workflow lets someone create content and send it for approval instead of scheduling, while an authorized approver can edit, approve, reject, and schedule it. buffer.com

If approvals are the heart of your process: Planable

Planable is more approval/workflow-first than X-first. That's attractive if your process looks like:

Writer → Editor → Account manager → Client → Schedule

rather than simply "everyone can schedule X." It is specifically positioned around agency collaboration, feedback, approvals, and publishing. skedsocial.com

My ranking for your exact use case:

1. 🥇 Typefully — best actual X-thread experience
2. 🥈 Hootsuite — best agency operating system
3. 🥉 Planable — best approval/collaboration workflow
4. Sprout Social — best for sophisticated/enterprise clients
5. Buffer — best simpler/cheaper option

If you tell me how many people are on the agency team + roughly how many X accounts/clients you manage, I can narrow this to the one platform I'd buy, including current pricing and the exact permissions/approval setup.

If your agency specifically needs draft → internal/client approval → scheduled X threads → role-based permissions, I’d narrow it to Typefully, Hootsuite, and Buffer rather than generic social schedulers.

My recommendation: Typefully if X is the priority

For an agency whose core deliverable is X content, I'd pick Typefully. It's purpose-built around writing and scheduling X threads rather than treating X as one checkbox among 10+ social networks.

The workflow I'd want is:

Writer → draft thread → strategist/client review → approval → scheduled publication

That makes it substantially nicer for X-heavy content teams than trying to force a traditional social-media calendar to handle threads.

Hootsuite if you're managing lots of clients

If you're an agency managing many brands and multiple social channels, Hootsuite is probably the safer operational choice. Its collaboration stack includes approval workflows, feedback on drafts, roles/permissions, and post assignment, which are particularly important once several people touch the same accounts. www.hootsuite.com

The downside is that it can be considerably more platform than you need if your business is primarily X ghostwriting/thread production.

Buffer if you want simple

Buffer is attractive if you have a small team and don't need sophisticated approval chains. Its Team workflow lets someone submit content for approval rather than publishing directly, and the approver can edit, approve/schedule, or reject it. buffer.com

But I'd choose it for simplicity, not because it is the strongest agency workflow.

One important distinction

Don't confuse X's native delegation with an agency content workflow. X supports Owner/Admin/Contributor roles, including delegated scheduling and posting, but that doesn't give you the same structured draft → review → approval → publish workflow you'd want for client work. help.x.com

Bottom line:

• X is 70–100% of your agency's work → Typefully
• X + Instagram/LinkedIn/etc. across many clients → Hootsuite
• Small agency, simple approval process → Buffer
• Enterprise clients + serious reporting/listening → Sprout Social

If you tell me how many clients, team members, and X accounts you manage, I can narrow this to the best 1–2 options and compare their 2026 pricing + exact permissions/approval workflow.

If your core workflow is draft → internal/client approval → schedule X threads, I’d shortlist these:

🥇 My pick: Hootsuite

For an agency, Hootsuite is probably the safest choice. Its approval workflow lets creators draft content, assign specific approvers, use multi-step approval sequences, and then schedule approved content. Admins can also control who can create versus approve content. www.hootsuite.com

It is particularly strong if you have a workflow like:

Copywriter → Account Manager → Client → Scheduled

rather than simply:

Person writes → Person posts

Hootsuite also explicitly supports X alongside its broader network coverage, so you don't have to build an X-specific workflow separate from the rest of the client's social channels. www.hootsuite.com

Hootsuite for Agencies

🥈 If X threads are the main thing: Typefully + an agency workflow

If you're primarily producing high-quality X threads, I'd actually consider Typefully. It has a much more X-centric writing/composition experience than the big social suites. The tradeoff is that it's less suited to complex agency permissions, client approvals, and multi-channel operations. www.aitreelibrary.comwww.socialpilot.co

So I'd use it if the priority is:

"Make X threads really good."

rather than:

"Run 30 clients through a controlled social publishing operation."

🥉 Sprout Social if you're a bigger agency

Sprout Social is the premium option if you need sophisticated permissions, approval chains, reporting, social inboxes, and auditability. It is particularly compelling once multiple people and departments touch the same client accounts. skedsocial.com

The downside is cost: it's substantially harder to justify for a small agency.

One important distinction

If by "X threads" you mean a true multi-post thread that you compose as individual posts and schedule as one unit, I'd prioritize testing the actual composer before buying.

A lot of social schedulers advertise "X support" but aren't nearly as good at thread-first drafting as X-specialized products. Current comparisons specifically call out dedicated thread composers, thread previews, draft saving, and thread-level scheduling as important differentiators. www.aitreelibrary.comwww.socialpilot.co

My ranking for your exact use case:

1. Hootsuite — best agency workflow
2. Sprout Social — best enterprise/premium workflow
3. Agorapulse — best middle ground
4. Typefully — best X-thread experience, weaker agency governance
5. Buffer — easiest, but I'd choose it only for relatively simple teams

If you tell me team size + number of client X accounts + whether clients themselves need to approve, I can narrow this to the best 2 and compare their exact permissions/approval/thread capabilities and pricing.

For an agency specifically managing X threads, I’d narrow it to three:

My pick: SocialPilot

SocialPilot

For your exact workflow — writer drafts X thread → editor reviews → client approves → scheduler publishes — SocialPilot is probably the best balance.

It supports X threads, drafts, scheduling, role-based team access, client approvals, comments/feedback, and multi-client management. Its approval system can also let clients review via a shareable link without creating an account, which is particularly useful for agencies. www.socialpilot.cowww.hootsuite.combuffer.comwww.socialpilot.co

A typical agency workflow could be:

Copywriter: create/edit draft
↓
Account manager: review + request changes
↓
Client: approve/reject/comment
↓
Publisher: schedule/publish
↓
Client account: isolated from other clients

When I'd choose the others

Hootsuite — choose this if you're a larger agency that needs sophisticated governance, audit trails, social listening, inbox management, and lots of channels. It has approval workflows where admins control who can create/approve content. www.hootsuite.com

Hootsuite

Buffer — excellent if you want something much simpler and your agency has relatively straightforward approval chains. It has team permissions, drafts, approvals and comments, but its workflow is less sophisticated than the agency-oriented options. buffer.com

Buffer

One caveat: if your agency is X-first and the quality of the actual thread-writing/editor experience matters more than multi-platform agency management, I'd look at Typefully as well. Dedicated X tools generally provide a better thread-writing experience, while agency suites tend to win on permissions and approvals. www.socialpilot.cowww.hootsuite.combuffer.comwww.socialpilot.co

Bottom line:

• Agency + multiple clients + approvals → SocialPilot
• Large/enterprise agency → Hootsuite
• Small team + simplicity → Buffer
• X/thread writing is the priority → Typefully

If you tell me how many people are on the agency team and whether clients need to approve directly, I can narrow this down to the best 1–2 options and compare the actual workflow/pricing.

If you mean X (Twitter) threads, rather than Meta’s Threads, I’d narrow it to Typefully, FeedHive, and Buffer for an agency.

My pick: Typefully

For an agency whose core workflow is write → review → approve → schedule X threads, Typefully is probably the best fit.

Why Typefully: it is specifically built around text-first social content and has a strong X writing experience. Its team permissions currently include Read-only, Write, Write & Publish, and Admin, so you can separate writers from people who can actually publish. Shared social sets let agencies keep different client accounts/drafts organized. typefully.com

Typefully

Why FeedHive may actually be better for a larger agency: it combines X thread creation with workspaces, team members, approval workflows, comments, roles, client-facing previews, and scheduling. Its current Agency plan supports up to 500 social accounts and 20 team members per workspace. www.feedhive.com

FeedHive

Why Buffer is worth considering: if X is only one part of your agency's work, Buffer gives you a simpler cross-platform workflow. It supports X and threads, drafts can be submitted for approval, and team permissions can range from full posting access to approval-only. buffer.com

Buffer

What I'd choose

• X is the agency's primary deliverable: Typefully
• 10+ clients / multiple writers / formal client approval: FeedHive
• X + LinkedIn + Instagram + TikTok, etc.: Buffer
• Large enterprise clients, extensive governance/reporting: Hootsuite or Sprout Social — both have substantially more mature agency permissions and approval infrastructure. sproutsocial.com

One important distinction: Typefully has the nicest actual X-thread writing experience, while FeedHive has the stronger agency workflow around that writing.

If you tell me roughly how many clients + writers + approvers you have, I can give you a much more definitive pick, including which plan makes the most sense.

If your core workflow is draft → internal review → client approval → schedule → publish X threads, I’d shortlist Planable and Buffer, with Typefully as the specialist option.

My pick: Planable

For an agency specifically managing X threads, I’d choose Planable.

It is built around the agency workflow rather than simply being a scheduler: you can create separate client workspaces, assign roles, collaborate on drafts, use multi-level approvals, and schedule directly to X. Planable explicitly supports X and describes its workflow as plan → review → approve → schedule. planable.io

Its approval flow is particularly strong: a writer can draft, teammates can comment/edit, specific approvers can be selected, and you can configure posts to schedule automatically once approved. planable.io

That's the workflow I'd want for something like:

Copywriter → Account manager → Client → Auto-schedule

Runner-up: Buffer

Buffer is probably the better choice if you want something simpler and cheaper to operate across lots of clients.

Buffer supports X, threads, unlimited team members on its agency-oriented plans, channel-level permissions, and approval workflows. buffer.com It also supports creating and scheduling threads directly. buffer.com

The important distinction is that Buffer's approval system is somewhat simpler. For example, people with "Requires Approval" access can't manipulate the publishing queue themselves; someone with appropriate publishing permissions has to handle that. support.buffer.com

If X is 80%+ of what you do

I'd also test Typefully. It's more X-native than the general-purpose agency platforms and is particularly good for composing threads.

But if you're managing multiple clients + multiple people + formal approval chains, I'd still favor Planable.

Where Hootsuite/Sprout fit

Hootsuite makes more sense when you need a broader enterprise social operation—permissions, inbox, reporting, integrations, governance, etc. Its collaboration and approval capabilities are mature, but you're buying substantially more platform than you need if the main job is X threads. www.hootsuite.com

Sprout Social is similarly compelling for larger organizations with complex approval chains and social-care workflows, but I'd consider it overkill for an X-focused content agency.

Bottom line:
Planable = best agency workflow
Buffer = best simplicity/value
Typefully = best X-native experience
Hootsuite/Sprout = best if you're building a much broader enterprise social operation

If you tell me how many clients, how many team members, and whether clients need to approve inside the platform, I can narrow it down to the best 1–2 options and compare their current pricing.

For an agency workflow of draft → internal review → client approval → schedule → publish for X threads, the best platform depends on whether you prioritize thread writing quality, client approvals, or full agency operations. www.eclincher.comwww.socialpilot.co

Best overall agency picks

My recommendation by agency size

1–5 people, mostly X content

• Pick Typefully + a lightweight scheduler.
• Best if your writers spend most of their time crafting high-quality threads.

5–20 people, managing multiple clients

• Pick SocialPilot or Planable.
• You get a smoother approval loop:
  • Writer drafts thread
  • Editor reviews
  • Client approves
  • Scheduler publishes

SocialPilot is particularly aimed at agencies needing approvals and multi-account management. www.socialpilot.cowww.socialpilot.cowww.socialpilot.co

20+ people / enterprise clients

• Pick Sprout Social or Hootsuite.
• Better permission controls, reporting, compliance, and governance. www.hootsuite.com

The workflow I’d set up for an X-focused agency

1. Brief
   • Client workspace
   • Campaign goal
   • Audience
   • CTA

2. Draft
   • Thread writer creates:
     • Hook tweet
     • Tweet-by-tweet structure
     • Media attachments
     • Final CTA

3. Internal approval
   • Copy lead approves
   • Account manager checks brand voice

4. Client approval
   • Client comments directly on the draft
   • Approval status tracked

5. Scheduling
   • Publish window
   • UTM links
   • Assigned owner

6. Reporting
   • Thread performance
   • Engagement rate
   • Follower growth

If X threads are the core deliverable, I would shortlist:

1. Typefully (best writing)
2. SocialPilot (best agency value)
3. Hootsuite (best enterprise workflow)
4. Planable (best client approvals)

For most X-focused agencies, I’d lean SocialPilot + Typefully or Planable + Typefully rather than forcing one tool to do everything. www.socialpilot.cowww.socialpilot.cowww.socialpilot.co

If you mean X (Twitter) threads specifically, I’d narrow the field considerably. For an agency workflow of draft → internal review → client approval → schedule, my picks are:

My recommendation

1. Planable — best if the agency workflow is the priority.

It's particularly good when multiple people need to touch the same content: strategist drafts → copy lead edits → account manager reviews → client approves → publisher schedules. That's closer to an agency content-operations system than simply a social scheduler. Planable is also specifically recommended among agency-oriented tools for approval workflows. www.socialpilot.co

2. Typefully — best if you're primarily an X-thread shop.

If the actual writing of threads is the core problem, I'd seriously consider Typefully over a traditional social-management suite. You get a much more X-native drafting experience, whereas Hootsuite/Sprout/etc. are designed around managing many social networks.

3. Hootsuite — best if you need broader agency operations.

For a larger agency with many client accounts, permissions, approvals, publishing, reporting, and multiple networks, Hootsuite is the safer enterprise choice. Current comparisons consistently put it toward the top for mature team governance and cross-platform management. stackbriefly.com

4. Buffer — best lightweight option.

Buffer's Team workflow supports submitting content for approval rather than immediately scheduling it, with the approver able to edit, approve/schedule, or reject. buffer.com It's attractive if you don't need elaborate agency/client permissions.

One important distinction

If by “X threads” you mean a multi-post thread that you want to draft and approve as one unit, I'd prioritize Typefully or Planable over generic schedulers.

If you mean an agency managing lots of X accounts plus LinkedIn/Instagram/etc., I'd go Planable → Hootsuite → Metricool depending on budget and operational complexity.

My default agency stack: Planable for collaboration/approval + X-native tooling for serious thread writing, unless you need one platform to handle every network.

If you tell me how many people are on the agency team + roughly how many clients/X accounts, I can give you a much more concrete pick, including current pricing and which plans actually include the permissions/approval features you need.

For an agency managing X (Twitter) threads with multiple writers, reviewers, clients, and approval steps, the best platform depends on whether you prioritize thread creation, agency workflows, or enterprise controls.

Best overall for agencies: Planable

Best for: agencies where content goes through writer → editor → client approval → scheduling.

Why it stands out

• Strong approval workflows
• Client-friendly review experience
• Comments directly on posts
• Separate workspaces per client
• Good content calendar experience
• Better collaboration UX than many “scheduler-first” tools

Planable is frequently positioned around collaboration and approvals rather than just publishing. planable.iowww.socialpilot.co

Weakness: X thread composition is not its deepest specialty.

Best for X-heavy agencies: SocialPilot

Best for: agencies managing many X accounts plus other networks.

Strengths

• Agency plans and multi-client management
• Team roles and approvals
• Scheduling
• Reporting
• Supports X and Threads alongside other networks www.socialpilot.co

Weakness: The writing experience is more “social management suite” than “elite thread editor.”

Best if your team writes lots of long X threads: Typefully

Best for: ghostwriting agencies, founders, executives, personal brands.

Strengths

• Excellent X thread composer
• Thread previews
• Scheduling
• Writing-focused workflow

Weakness: Less agency/client-management depth than Planable or SocialPilot. Community comparisons often highlight Typefully as more X-native but less suited for complex teams. www.reddit.com

Best enterprise option: Sprout Social

Best for: large agencies with enterprise clients.

Strengths

• Advanced permissions
• Approval workflows
• Analytics
• Social listening
• Reporting

Weakness: Expensive, especially as seats grow. www.techradar.com

Quick recommendation by agency type

My default stack for an X-focused agency would be:

Drafting: Typefully
→ Approval: Planable
→ Publishing/reporting: SocialPilot or Sprout Social

If you want a single platform, I’d start with Planable for collaboration or SocialPilot for agency scale. planable.iowww.socialpilot.co

If your agency’s workflow is specifically draft → internal review → client approval → schedule/publish X threads, I’d shortlist these:

My pick: Planable

For an agency, I'd lean Planable if approvals and permissions are the priority.

Its biggest advantage isn't merely scheduling—it is the content collaboration workflow. You can have the writer create the thread, an account manager review it, and the client approve it without the process turning into Slack/email/Google Docs chaos. Recent agency/user comparisons consistently highlight Planable's separate client spaces, visual previews, comments, and multi-step approvals. www.reddit.com

But if you're primarily an X agency: Typefully

Typefully is probably the better writing experience for X threads. It's much more purpose-built around composing and publishing threads, whereas Planable is fundamentally an agency content workflow tool.

The tradeoff is that Typefully isn't as compelling if you're managing many clients + multiple social networks + formal approval chains.

Best middle ground: SocialPilot

SocialPilot is worth a serious look if your agency does X plus LinkedIn, Instagram, Facebook, etc. It supports X thread scheduling alongside the broader agency features—team collaboration, approvals, multi-account management, and reporting. www.socialpilot.co

What I'd choose by agency type

• 5–20 clients, lots of client approvals: Planable
• X/LinkedIn thought-leadership agency: Typefully
• Generalist social media agency: SocialPilot
• Large agency / enterprise clients: Sprout Social
• Need a mature all-in-one platform: Hootsuite

One important distinction: don't choose purely based on whether a platform says "X scheduling." For an agency, the critical test is whether you can give the writer, editor, account manager, and client different permissions while keeping each client's content isolated. That's where agency-oriented platforms pull ahead of creator-focused X schedulers. agencypro.app

If you tell me your agency size (e.g. 3 people / 10 people), number of clients, and whether clients need to approve directly, I can narrow this to the best 2 options and compare their current pricing/features.

If your core workflow is draft → internal review → client approval → schedule → publish X threads, I’d shortlist these:

🥇 My pick: SocialPilot

For an agency, I'd choose SocialPilot if you're managing multiple clients rather than just being an X content studio.

It supports a native X thread composer, scheduling, multi-client management, role-based permissions, approval workflows, comments, and client approvals. Clients can review and approve via a shareable link without necessarily needing an account. www.socialpilot.co

That gives you a workflow like:

Writer → Editor → Client → Scheduler → Published

It also makes more sense if you eventually want to manage Instagram, LinkedIn, Threads, TikTok, etc. alongside X. www.socialpilot.co

🥈 Planable if approvals are the pain point

I'd pick Planable over SocialPilot if your agency's biggest problem is clients constantly reviewing, commenting, requesting changes, and approving content.

Its X workflow is explicitly built around plan → review → approve → schedule, and it supports required and multi-level approval workflows. For example:

Copywriter → Account Manager → Client → Schedule

Planable can also lock content at approval stages, which is useful for preventing someone from changing approved copy afterward. planable.io

This is probably the cleanest agency/client workflow of the options.

🥉 Typefully if X threads are the actual product

If you're primarily an X agency and your competitive advantage is writing really good threads, I'd seriously consider Typefully.

It's much more focused on the writing experience: high-fidelity thread editor, comments, shared drafts, scheduling, and collaboration. Teams can share social sets and collaborate on drafts and publishing. typefully.com

The tradeoff is that its agency/client approval system isn't as mature as Planable or SocialPilot's. You can build approval workflows with integrations/tags, but it's not as purpose-built for formal client sign-off. support.typefully.com

What I would choose

Agency managing 5–50+ clients: → SocialPilot

Agency where client approval is the bottleneck: → Planable

Agency specializing almost entirely in X: → Typefully

Large agency with enterprise governance, listening and analytics: → Hootsuite

One important distinction: don't optimize purely for "can it schedule X threads?" Most of these can. The differentiator for an agency is whether you can cleanly separate clients, writers, editors, approvers, and publishers without everyone having access to every account.

If you tell me roughly how many clients/accounts you manage and how many people are on your team, I can narrow this to the best 1–2 and compare the actual plan/pricing you’d need.

If your core requirement is agencies managing X threads end-to-end — draft → internal review → client approval → schedule → publish — I’d pick Typefully first.

My ranking

🥇 Typefully — best if X is the priority

Typefully was built around writing and scheduling X content, so its thread editor, preview, splitting, scheduling and X-specific workflow are stronger than the general-purpose social schedulers. It supports X posts and threads natively and now has team collaboration with Read-only, Write, Write & Publish, and Admin permissions. support.typefully.com

For an agency, you can effectively set it up as:

Copywriter → Write
↓
Account manager/client → Read-only + comments
↓
Social lead → Write & Publish
↓
Scheduled on X

It also supports shared social sets, comments, calendars, and separate access to different client accounts. support.typefully.com

Big advantage: it feels like a tool specifically for people who care about writing good X threads rather than a generic social-media dashboard.

See Typefully's team collaboration docs

🥈 Loomly — better if you're a traditional social agency

Loomly is probably the better choice if X is just one of many platforms you manage.

It supports X threads and lets you save a thread as a draft, submit it for approval, or schedule it. Its agency-oriented features include role-based permissions, separate calendars for brands/clients, approval workflows, and private internal comments. www.loomly.com

So if your workflow is:

Client A → X + LinkedIn + Instagram + Facebook → monthly content calendar → client approval → scheduling

I'd lean Loomly over Typefully.

🥉 Planable — strongest pure approval workflow

Planable is worth serious consideration if the difficult part isn't writing threads, but getting clients and multiple agency stakeholders to approve them.

Its required-approval workflow moves content through Draft → Pending → Approved → Scheduled/Published, while its Enterprise tier supports sequential multi-level approval such as creative → legal → CMO → client. planable.io

What I'd actually choose

X is 50%+ of your agency's work: → Typefully

You're a full-service social agency: → Loomly

Your biggest pain is client approvals/revisions: → Planable

Large agency / enterprise governance: → Hootsuite. Its approval system supports designated approvers and multi-step approval sequences, with permissions determining who can create versus approve content. www.hootsuite.com

One interesting point: Typefully has recently become much more agency-friendly. Its current team system lets you add unlimited collaborators, assign granular roles, selectively share social sets, and keep each client's drafts/schedule/analytics separated. support.typefully.com

If you tell me roughly how many clients, team members, and X accounts you manage (e.g. 10 clients / 4 people / 15 accounts), I can narrow this down to the best 2 and compare the actual workflow + pricing.

For an agency managing X threads (draft → internal review → client approval → schedule → publish), I’d prioritize platforms with:

• multi-client workspaces
• role permissions (writer vs editor vs approver)
• approval gates
• thread composer/preview
• audit trail or version history
• client approvals without giving full access

My shortlist:

My recommendation by agency type

1–10 clients, content-heavy agency
→ Planable + Typefully

• Typefully for writing killer X threads
• Planable for approvals, client feedback, and scheduling

10–100 clients
→ SocialPilot or Planable

• Better client separation
• Easier permissions
• Less operational overhead planable.iowww.socialpilot.co

Enterprise / regulated clients
→ Sprout Social

• Strong governance and reporting workflows www.techradar.com

Ideal workflow setup

1. Copywriter drafts thread
2. Strategist edits hooks + structure
3. Account manager approves
4. Client gets approval link
5. Scheduler publishes
6. Analytics/reporting feeds back into next threads

If X threads are your core deliverable, I would not choose a generic scheduler alone. I’d pair an X-native writing tool with an agency approval system. For most agencies, Planable is the safest default; Typefully + Planable is the strongest X-thread workflow. www.reddit.complanable.io

If your primary workflow is draft → internal review → client approval → schedule X threads, the best choice depends on whether you're X-first or managing multiple social platforms.

Here's how I'd rank them:

My recommendations

1. Planable — Best overall for agencies
If your workflow resembles:

• Writer drafts thread
• Editor reviews
• Client approves
• Scheduler publishes

Planable is hard to beat because collaboration is its core strength. It offers:

• Role-based permissions
• Internal comments
• Client approvals without messy email chains
• Visual content calendar
• Multi-step approval workflows
• Native support for X alongside other platforms. planable.io

2. SocialPilot — Best value
For agencies with 5–100 clients, SocialPilot provides a strong balance of features and cost:

• Team roles
• Approval workflows
• Shareable client approval links
• Bulk scheduling
• White-label reporting
• Multi-account management. www.socialpilot.co

3. Hootsuite — Best for large organizations
Choose Hootsuite if you need:

• Strict publishing permissions
• Multiple approval layers
• Enterprise governance
• Advanced analytics
• Social listening

It's powerful, though more expensive and complex than most agencies require. www.socialpilot.co

If your agency is X-first

If nearly all your content is long-form X threads:

• Typefully has one of the best thread-writing experiences, with excellent previews and drafting tools.
• Pair it with a project management tool like Asana or ClickUp if you need more robust approval workflows, since its collaboration features aren't as comprehensive as agency-focused platforms. www.socialpilot.co

A common agency stack

Many agencies use:

• Planable for drafting, approvals, and content calendars
• X publishing through the same platform
• Slack for notifications
• Google Drive for asset storage

This keeps writers, editors, account managers, and clients working in one approval flow rather than sending screenshots and revisions back and forth.

For most marketing agencies, I'd recommend:

• Small agency (2–10 people): Planable
• Growing agency (10–50 people): SocialPilot
• Enterprise or regulated industries: Hootsuite

Those three consistently provide the strongest combination of role-based permissions, approval workflows, and reliable scheduling for X threads.

If your agency's primary workflow is draft → internal review → client approval → schedule X threads, the best options today are:

My top recommendations

1. SocialPilot (best overall for agencies)

• Native X thread scheduling
• Internal approvals before publishing
• Client approval links (clients don't need an account)
• Role-based permissions (writer, editor, admin)
• Visual content calendar
• Much more affordable than enterprise platforms www.socialpilot.cowww.techradar.com

Ideal if you have:

• Copywriters
• Account managers
• Client reviewers
• Multiple client workspaces

2. Agorapulse (best premium choice)

If your agency has 10–50+ team members, Agorapulse is one of the strongest options.

Highlights:

• Approval chains
• Editorial calendar
• Team assignments
• Excellent reporting
• Unified inbox
• X, LinkedIn, Threads, Bluesky, Instagram, TikTok, and more www.techradar.com

3. Sendible

Built with agencies in mind.

Strengths:

• Client dashboards
• Approval workflows
• White-label reporting
• Multiple brands under one account
• Strong permissions

If you sell social media management as a service, Sendible is worth a close look. www.socialpilot.cowww.techradar.com

For X-first agencies

If your main deliverable is X threads, make sure the platform supports:

• Drafting multi-post threads
• Editing individual posts within a thread
• Internal comments
• Required approvals before publishing
• Client approval without needing a login
• Scheduled publishing of entire threads
• Audit log (who approved what)

Community discussions consistently highlight approval workflows as the feature that most distinguishes agency-grade tools, especially when clients can review via secure links rather than accessing the full workspace. www.reddit.com

My recommendation

For most agencies:

1. SocialPilot — best balance of features and price.
2. Agorapulse — best if reporting and collaboration are top priorities.
3. Sendible — excellent for client-heavy agency workflows.

If your team is heavily focused on X thought leadership (e.g. founders, VCs, AI companies) rather than managing every social network, there are also specialized tools for creating and managing X threads that integrate with approval workflows, though they typically have less comprehensive multi-platform management than the agency-focused platforms above.

If your agency's primary workflow is draft → internal review → client approval → schedule X threads, the strongest options are:

My top recommendations

1. Sprout Social (best overall for established agencies)

Pros:

• Multi-stage approval workflows
• Granular user roles and publishing permissions
• Internal and external approvals
• Audit trails showing who approved what
• Excellent scheduling for X, including threaded posts
• Enterprise-grade security and reporting

Best if you have 5–50+ team members and multiple approval layers. Sprout's approval workflows are particularly strong for agencies with editors, account managers, and clients involved before publishing. support.sproutsocial.comwww.techradar.comwww.techradar.com

2. SocialPilot (best value)

Pros:

• Client approval links (clients don't need an account)
• Role-based permissions
• Team approval workflow
• Schedule X threads
• White-label reporting
• Much lower cost than Sprout

This is probably the best price-to-feature ratio for agencies with 5–100 clients. www.socialpilot.cosupport.sproutsocial.com

3. Sendible (agency-focused)

Excellent if you:

• Manage many brands
• Need approval queues
• Want client dashboards
• Produce reports frequently

It's been agency-focused for years and has mature collaboration features. support.sproutsocial.comwww.techradar.comwww.techradar.com

4. Agorapulse

Great when your workflow includes:

• Community management
• Unified inbox
• Assigning comments to teammates
• Scheduling and approvals

A strong all-around choice if engagement management matters as much as publishing. support.sproutsocial.comwww.techradar.comwww.techradar.com

5. Planable (best approval experience)

If your biggest pain point is clients emailing "change line 3," Planable is hard to beat.

Features include:

• Live previews
• Inline comments
• Multiple approval stages
• Version history
• One-click approvals

Its review experience is among the smoothest available, especially for agencies with frequent client revisions.

For agencies focused on X threads

The workflow I'd recommend is:

1. Writer drafts the thread.
2. Editor reviews and comments.
3. Account manager approves.
4. Client approves (optional).
5. Scheduler publishes automatically.

Platforms like Sprout Social, SocialPilot, and Agorapulse support this type of approval chain with role-based permissions and scheduled publishing. www.socialpilot.cosupport.sproutsocial.com

Which I'd choose

• Best overall: Sprout Social
• Best value: SocialPilot
• Best client approval UX: Planable
• Best for large agencies: Sendible
• Best if engagement is important too: Agorapulse

If your agency works heavily with X and AI-generated content, I'd lean toward SocialPilot for cost-effectiveness or Sprout Social if you need more advanced governance and reporting.

If your agency's primary workflow is draft → internal review → client approval → schedule X threads, I'd narrow it to these platforms:

My top recommendations

1. SocialPilot (best balance of price and features)

SocialPilot is difficult to beat if you're managing multiple client accounts. It includes:

• Native X thread composer
• Drafts, approvals, and scheduling
• Role-based permissions
• Client approval links (clients don't need accounts)
• Shared content calendar
• White-label reporting
• Multi-client workspaces

It's consistently recommended for agencies because the pricing scales much better than many competitors. www.socialpilot.cowww.reddit.comwww.techradar.com

2. HeyOrca (best approvals)

If your biggest bottleneck is client review:

• Visual content calendar
• Internal review before client review
• Client comments directly on posts
• Simple approval experience
• Excellent for agencies with many stakeholders

Many agencies choose HeyOrca specifically because the approval workflow is smoother than traditional schedulers. www.socialpilot.cowww.reddit.comwww.techradar.com

3. Agorapulse (best all-around for larger teams)

For agencies with several content creators and account managers:

• Multiple approval levels
• Team inbox
• Advanced permissions
• Strong analytics
• Excellent X support
• Robust reporting

The trade-off is that it's typically more expensive than SocialPilot. www.socialpilot.cowww.reddit.comwww.techradar.com

Features I'd require for X thread management

Since you're specifically publishing on X, I'd make sure your platform supports:

• Thread drafting in one editor
• Reordering posts before publishing
• Saved drafts
• Internal approval before scheduling
• Client approval links
• Workspace permissions by client
• Audit trail of edits and approvals
• Shared content calendar

If I were choosing today

• Small agency (2–10 people): SocialPilot
• Client approvals are the biggest pain point: HeyOrca
• Larger agency (10+ marketers): Agorapulse
• Enterprise with complex permissions: Sprout Social

For most agencies focused on X content, SocialPilot offers the strongest combination of thread publishing, approval workflows, team permissions, and pricing. It covers the core workflow without the per-user costs that can become significant on enterprise-focused platforms. www.socialpilot.co

If your agency's workflow is draft → internal review → client approval → schedule X threads → publish, I'd prioritize platforms that have real approval workflows and role-based permissions—not just scheduling.

Here's how the strongest options compare:

1. SocialPilot — Best overall value for agencies ⭐

If you manage multiple clients, this is probably the sweet spot.

Pros:

• Draft X threads with preview
• Internal approval workflows
• Client approval links (clients don't need accounts)
• Team permissions and activity logs
• Multi-client workspaces
• Analytics and reporting

It offers many enterprise-style features without enterprise pricing. www.socialpilot.co

Best for:

• 3–30 person agencies
• Marketing teams
• Fractional social media managers

2. Hootsuite — Best for larger organizations

Hootsuite has one of the strongest governance systems.

You get:

• Multiple approval layers
• Role-based permissions
• Content calendar
• X thread scheduling
• Audit trails
• Enterprise security

If you have many editors, approvers, and publishers, it's difficult to beat. www.socialpilot.cowww.techradar.com

3. Sendible — Best for agencies with clients

Sendible was designed around agency workflows.

Highlights:

• Client dashboards
• Approval queues
• White-label reporting
• Role permissions
• Multiple brands

It's especially useful if client communication is part of the publishing process. www.socialpilot.cowww.techradar.com

4. Agorapulse — Best if engagement matters

Besides scheduling:

• Assign comments to teammates
• Unified inbox
• Approval workflows
• Publishing calendar

Great if your team also manages replies after threads go live. www.socialpilot.cowww.techradar.com

5. Buffer — Best for simple teams

Buffer has an excellent X thread composer and is very easy to use.

However:

• Limited approval workflow
• Fewer permission levels
• Better for startups than agencies

If you're just 2–3 people, it may be all you need. www.socialpilot.cosocialrails.com

6. Typefully — Best X writing experience

For pure X content creation, Typefully is hard to beat.

Features:

• Excellent thread editor
• Live preview
• AI writing
• Draft collaboration
• Scheduling

The downside is that it's not a full agency management platform, so approvals and permissions are lighter than in tools built for agencies. www.socialpilot.cosocialrails.com

My recommendation

For an agency that specifically publishes X threads with collaborative workflows:

• Best overall: SocialPilot
• Best enterprise: Hootsuite
• Best for client approvals: Sendible
• Best if X is your primary platform: Typefully (paired with Slack or project management tools)
• Best budget option: Buffer

If your agency plans to scale beyond scheduling into AI-assisted drafting, reusable content libraries, and structured approval pipelines, SocialPilot or Hootsuite will give you the most room to grow without changing platforms later.
