Answers that name a competitor

If you’re managing email campaigns for multiple client accounts and want to avoid constant logins/logouts, look for an agency-focused email marketing platform with:

• A master dashboard for multiple client accounts
• Role-based access for your team and clients
• Client-specific reporting dashboards
• White-label reports (if you present results under your agency brand)
• Reusable templates and automation workflows

Some tools that fit this workflow:

A practical setup many agencies use:

1. Campaign platform: one of the tools above for sending and automation
2. Reporting layer: client dashboards or automated monthly reports
3. Client access: give clients view-only permissions where possible instead of sharing credentials
4. Templates: maintain a reusable library of approved layouts and workflows

If you manage 5–20 clients, I’d usually prioritize a tool with a true agency dashboard rather than just creating separate accounts under one email address. Zoho Campaign Monitor

The best choice depends mostly on your client mix:

• E-commerce clients: prioritize revenue attribution and integrations (often Klaviyo/ActiveCampaign-style workflows). BestSends
• Local businesses/service clients: prioritize easy reporting and client approvals.
• Large retainers: prioritize CRM integration, permissions, and white-label reporting.

If you tell me roughly how many client accounts you manage and whether they’re mostly e-commerce, B2B, or local businesses, I can narrow it down.

If you’re managing email campaigns for multiple clients, I’d separate the problem into two parts: campaign execution and cross-client reporting.

• ActiveCampaign — worth considering if you need to actually build automations, sequences, CRM workflows, and campaigns across multiple client accounts. Current agency-focused sources highlight its multi-account/partner tooling. BestSends
• AgencyAnalytics — particularly useful if the pain point is reporting. You can manage multiple clients from one account, connect email data sources including ActiveCampaign, schedule white-label reports, and create roll-up reports across clients. AgencyAnalytics Knowledge Base AgencyAnalytics Knowledge Base AgencyAnalytics Knowledge Base
• Campaign Monitor — another option if your main requirement is straightforward email campaign management across client brands; recent agency-focused comparisons specifically discuss its multi-client workflow. Hack'celeration

What I'd consider for your workflow

If you want one system to run the campaigns: look at ActiveCampaign.

If you already use different email platforms for each client and mainly want one dashboard/reporting layer: AgencyAnalytics is a better fit. It can aggregate data across clients and automate branded reports, so you don't have to repeatedly log into every client's platform just to pull numbers. AgencyAnalytics AgencyAnalytics

If you tell me how many clients you manage and whether these are newsletters, automated email/CRM campaigns, or cold outreach, I can narrow it down to the most suitable setup.

If your agency needs to run newsletters + automations + client-facing performance dashboards across multiple clients, I’d look at the market in two layers: the email execution platform and the agency reporting layer.

The dashboard question is important

If by "performance dashboards" you mean a single agency portal where each client can log in and see email results alongside Google Ads, Meta, SEO, etc., I wouldn't necessarily make the email platform do that.

A setup such as:

Email platform → reporting connector → white-label agency dashboard

can be considerably cleaner. For example, AgencyAnalytics is specifically designed to pull email campaign performance into broader client reporting dashboards; it doesn't send the emails itself. US Tech Automations

My practical architecture

For an agency managing, say, 10–50 clients, I'd seriously consider:

• General SMB/B2B clients: ActiveCampaign or HighLevel
• Ecommerce clients: Klaviyo
• Client-facing reporting: AgencyAnalytics or another white-label reporting layer
• Your agency: standardized templates, automation recipes, UTM conventions, dashboards, and onboarding checklist

That avoids forcing every client into the same email platform when their underlying needs are different.

If you tell me roughly how many clients you manage, whether they're mostly B2B/ecommerce/local businesses, and whether clients need their own login, I can narrow this to 2–3 platforms and compare actual pricing, white-labeling, client isolation, automations, and reporting.

A setup such as:

Email platform → reporting connector → white-label agency dashboard

can be considerably cleaner. For example, AgencyAnalytics is specifically designed to pull email campaign performance into broader client reporting dashboards; it doesn't send the emails itself.

My practical architecture

If you're running an agency with multiple client accounts, I’d separate the problem into two layers: email execution/automation and client-facing reporting. There isn't one platform that is equally strong at both.

My shortlist

Current agency-focused comparisons consistently highlight ActiveCampaign for automation/multi-account workflows, while AgencyAnalytics is specifically built around consolidating client reporting. US Tech Automations BestSends

What I'd actually build

For most agencies, I'd use:

ActiveCampaign + AgencyAnalytics

ActiveCampaign handles:

• Client newsletters
• Segmentation
• Welcome sequences
• Lead nurturing
• Behavioral automations
• Forms/lists
• Email performance

Then AgencyAnalytics becomes the client-facing reporting layer. It can pull email data alongside GA4, Google Ads, social, SEO, etc., and create branded/white-label dashboards and automated reports. AgencyAnalytics AgencyAnalytics

It also supports separate client dashboards, custom branding and agency-wide roll-up reporting, which is particularly useful once you're managing a meaningful number of accounts. AgencyAnalytics AgencyAnalytics

When I'd choose something else

HubSpot — If your clients need CRM + email + sales pipelines + marketing automation in one system. AgencyAnalytics can also pull HubSpot email metrics into client dashboards. AgencyAnalytics

Klaviyo — If most of your clients are ecommerce brands. I'd favor it when Shopify/customer behavior, product recommendations, revenue attribution and sophisticated ecommerce flows are central to the work.

Brevo — Worth considering if you're managing a large number of relatively small/local-business clients and keeping software costs tightly controlled.

Campaign Monitor — Particularly interesting if the agency's core service is newsletters rather than complex lifecycle automation. AgencyAnalytics can consolidate data from multiple Campaign Monitor accounts into centralized dashboards and provides white-label reporting. AgencyAnalytics

The key distinction

If by "centralize" you mean "I want one login where my team can manage 20 clients' email accounts", I'd lean toward ActiveCampaign/Campaign Monitor.

If you mean "I want one place where my team and clients can see every client's email + ads + website + SEO performance", I'd use AgencyAnalytics as the reporting hub, with the email platform underneath it.

If you tell me roughly how many clients you manage (e.g. 5, 20, 50+) and whether they're mostly B2B, local businesses, or ecommerce, I can narrow this down to a specific stack and estimate the monthly cost.

Yes. What you’re describing is usually called a multi-tenant agency platform, white-label platform, or client workspace platform. The ideal setup is:

• One agency admin account
• Separate workspace per client/brand
• Each client has its own:

• Brand templates (logos, colors, fonts, assets, layouts)
• Users and permissions
• Approval workflows
• Billing/subscription
• Usage tracking
• Data isolation
• Agency can switch between clients from one dashboard

A few platforms that fit parts of this model:

For more agency-as-a-SaaS models (where you want clients to feel like they’re logging into your product), look at white-label/multi-workspace tools:

• StackFill — built around agency templates, client workspaces, isolated templates, and per-client billing options. StackFill
• Vercid — focuses on branded client workspaces with custom branding, roles, and billing widgets. Vercid
• Agency Label — combines client management, reporting, invoicing, and white-label portals. Agency Label

If you’re building something closer to a creative production platform (think “each client has their own Canva-like environment”), I’d look for:

• Template inheritance: agency creates master templates → client gets controlled variants
• Field locking: clients can edit copy/images but not break layout
• Role hierarchy: agency admin → account manager → client editor → client approver
• Client billing isolation: each client can have their own Stripe/customer account
• Brand tokens: colors/fonts/assets stored per workspace
• Audit trail: who changed what and when

A common architecture is:

Agency Account
│
├── Client A Workspace
│   ├── Brand Kit
│   ├── Templates
│   ├── Users/Roles
│   └── Billing
│
├── Client B Workspace
│   ├── Brand Kit
│   ├── Templates
│   ├── Users/Roles
│   └── Billing

If you mean for a marketing/design agency, a franchise network, or a SaaS product you want to resell under your own brand, the best options differ quite a bit.

Yes. What you’re describing is essentially multi-client brand management: one agency account, with each client having its own brand assets/templates, users, permissions, and ideally billing.

A few platforms are particularly relevant:

• Marq — probably the closest functional match. It supports brand-specific template libraries, locked templates, brand assets, user/group permissions, approval workflows, and multiple brand kits. It also explicitly supports agencies working across multiple clients/brands. Marq Marq Help Center Marq Help Center
• Canva Enterprise/Business — strong for agencies managing multiple client brands. It has Brand Kits, Brand Folders, Brand Templates, and controls over who can edit/publish/approve. Canva
• Marq is especially interesting if the workflow is “agency builds templates → client gets access → client can customize but can't break the brand.” Its locking and permissions are designed specifically for that. Marq Help Center Marq

The important distinction: billing

If by “billing per client” you mean:

Client A has 5 seats and pays $X/month, Client B has 12 seats and pays $Y/month, while the agency administers everything from one place

that's a more specific requirement. Many design platforms handle client separation + permissions, but don't necessarily provide a true agency reseller/multi-tenant billing layer.

If you're actually looking to build or buy a platform for your agency, I'd define the ideal architecture as:

Agency
→ Client A workspace
→ Client B workspace
→ Client C workspace

Each client workspace has:

• Brand kit / logos / fonts / colors
• Template library
• Template-level permissions
• Client users + roles
• Approval workflows
• Asset library
• Usage/storage limits
• Separate billing/subscription
• Client-facing login/portal
• Agency admin who can switch between clients

And ideally, one template can be reused across clients while automatically swapping the brand kit—Marq now supports this kind of brand-kit swapping. Marq Help Center

If you tell me what kind of templates you're managing (social posts, proposals, PDFs, ads, email, print, etc.) and whether the clients themselves need to log in and edit them, I can narrow this down to the 3–5 platforms that actually fit.

And ideally, one template can be reused across clients while automatically swapping the brand kit—Marq now supports this kind of brand-kit swapping.

For email-performance reporting specifically, I’d shortlist these:

• agencyanalytics.com — strongest general-purpose choice. It has a dedicated email-marketing dashboard, supports data from Klaviyo, HubSpot, ActiveCampaign, and Mailchimp, and offers white-label dashboards, custom branding, client logins, custom domains, and automated reports. AgencyAnalytics AgencyAnalytics
• sendlytics.co — strongest email-focused option. It is specifically built around email reporting, with white-label dashboards, client/staff access, segment performance, annotations/goals, and daily/weekly/monthly campaign and flow monitoring. Sendlytics
• mailbreeze.com — worth considering if you also want email execution. It combines multi-client email management with white-label templates, custom domains, client-specific analytics, and automated branded PDF reports. MailBreeze
• zoho.com — better if you need highly customized BI. It supports branded client dashboards, custom domains, role-based access, data blending, and scheduled reports, so it's more flexible if email performance needs to sit alongside CRM, sales, or advertising data. Zoho

My pick

If your core requirement is “each client gets a polished dashboard showing their email campaigns/flows, completely under our agency brand”, I would start with AgencyAnalytics vs. Sendlytics.

The distinction is basically:

If you tell me which email platform(s) you use (Klaviyo, Mailchimp, HubSpot, etc.) and roughly how many clients you have, I can narrow this to the most suitable 2–3 systems and compare pricing/features.

If your focus is specifically email performance plus a polished agency/client experience, I’d start with AgencyAnalytics.

• White-labeling: custom logo, colors, domain, and branded report emails are supported on applicable plans. AgencyAnalytics
• Email-specific dashboards: it has a dedicated email marketing dashboard that can consolidate metrics from platforms such as Klaviyo, HubSpot, ActiveCampaign, and Mailchimp. AgencyAnalytics
• Custom client views: you can tailor dashboards around the KPIs your clients care about—opens, clicks, conversions, engagement by segment, bounce trends, etc. AgencyAnalytics
• Broader agency reporting: useful if you eventually want to combine email with paid media, SEO, analytics, or other channels rather than maintaining a separate reporting system. AgencyAnalytics

agencyanalytics.com

Alternatives worth considering

• Zoho Analytics — stronger if you want highly customized dashboards, data blending, role-based client access, and automated reports. It supports white-label dashboards with agency branding and custom domains. Zoho
• DataLion — worth looking at if sophisticated, interactive dashboards and per-client branding are more important than having a turnkey email-reporting template. DataLion
• DataReportive — more focused on automated white-label agency reporting, including live client dashboards and per-client permissions. DataReportive

My practical shortlist: AgencyAnalytics for the easiest agency-ready solution; Zoho Analytics if you need deeper customization/data modeling.

If you tell me which email platform you use (Klaviyo, Mailchimp, HubSpot, ActiveCampaign, etc.) and roughly how many clients you have, I can narrow this to the best 2–3 options and compare pricing/features.

For an agency managing multiple ecommerce clients and needing both email + SMS from a centralized interface, I’d narrow it to Klaviyo vs. HighLevel, with the right choice depending on whether you're primarily an ecommerce retention agency or a broader marketing agency.

If you're an ecommerce-focused agency: Klaviyo

Klaviyo is probably the more natural fit if your clients are Shopify/DTC brands and your team is actually running email/SMS retention.

Klaviyo lets one login access and switch between multiple client accounts, with permissions that can differ by account. It also supports both email and SMS within those accounts. Klaviyo Help Center

The big advantage is that the platform is designed around ecommerce data—customers, products, orders, browsing behavior, abandoned carts, segmentation, flows, etc.

One caveat for agencies: Klaviyo's multi-account setup is more like "manage a portfolio of separate brands" than "one agency operating system." Shared billing is available in certain configurations, but has account-count limits. Klaviyo Help Center

If you want a true agency operating system: HighLevel

HighLevel is more explicitly designed around the agency model.

You get an Agency view → client sub-accounts, and those sub-accounts can independently handle email, SMS, automations, contacts, domains, etc. HighLevel also supports centralized management and bulk actions across client accounts. HighLevel Support Portal HighLevel Support Portal

It supports both bulk email and SMS from the same platform, and its agency plans support things like rebilling and SaaS configurations. HighLevel Support Portal HighLevel Support Portal

That makes HighLevel particularly interesting if your business model is:

Agency → 20/50/100 ecommerce clients → each client gets their own account → agency manages everything centrally → client gets charged monthly.

My practical distinction

I'd think about it this way:

• Shopify/DTC retention agency → Klaviyo
• Full-service marketing agency → HighLevel
• Agency wants to white-label/resell the software → HighLevel
• Agency primarily builds sophisticated ecommerce email/SMS flows → Klaviyo
• Agency wants one operational dashboard across lots of unrelated clients → HighLevel

If you tell me roughly how many clients you manage (e.g. 10, 50, 200+) and whether they're mostly Shopify, I can compare Klaviyo, HighLevel, Attentive, Yotpo, and Omnisend specifically for the agency model, including estimated cost structure and multi-client workflow.

Klaviyo is probably the more natural fit if your clients are Shopify/DTC brands and your team is actually running email/SMS retention.

Yes. For a small agency managing multiple client lists, audience segments, and split tests, you’ll usually want a platform with:

• Multi-client workspaces/subaccounts
• Segmentation rules (tags, behaviors, demographics, lifecycle stages)
• A/B testing (subject lines, content, offers, send times, landing pages)
• Reusable templates/workflows
• Client reporting and permissions

The best fit depends on whether you mean email/SMS lists or website conversion testing.

vwo.com

More enterprise-oriented:

• A/B testing
• Segmentation

Best for: larger clients with traffic volume.

My shortlist for a small agency

A key question: are you trying to manage email/SMS audience lists (e.g., “send different offers to different customer groups”) or website experiments (e.g., “50% see landing page A, 50% see B”)? The ideal platform is quite different.

Yes. If by “manage segmentation and split testing across many client lists” you mean an agency needs to run campaigns for multiple clients without building a custom system, there are a few good fits.

My shortlist

ActiveCampaign is probably the first one I'd investigate for a small agency. Its Partner Portal is explicitly designed for agencies/resellers managing multiple client accounts, with an account dashboard and user management. ActiveCampaign Help Center ActiveCampaign Help Center

It also has unusually flexible testing: standard campaign split tests plus automation splits of 2–10 paths, including percentage-based splits and tests that can automatically determine a winning path. ActiveCampaign Help Center ActiveCampaign

Klaviyo Help Center Klaviyo Help Center Its flow A/B testing can split audiences and compare different messages, timing, discounts, or entire branches. Klaviyo Help Center

klaviyo.com

Customer.io is attractive if your agency does more sophisticated lifecycle/behavioral marketing. Its segments can be based on characteristics and behaviors and used as triggers, filters, recipient lists, and conversion criteria. Separate workspaces keep each client's people, automations, and metrics isolated. Customer.io Customer.io

customer.io

One important distinction

If you're talking about something like:

“I have 30 client lists. I want to upload/manage them centrally, create reusable audience rules, randomly split each list 50/50, run different campaigns, and see aggregate results across clients.”

—that's a slightly different problem from ordinary email marketing. You may want an agency experimentation/segmentation layer rather than just an ESP.

If you tell me what channels you're testing (email, SMS, ads, etc.), roughly how many client lists/accounts you manage, and whether each client needs their data completely isolated, I can narrow this down to 2–3 platforms and explain the workflow I'd use for each.

For an agency managing multiple clients’ email work, I’d prioritize platforms with:

• Tenant/client isolation (Client A cannot see Client B’s lists, campaigns, mailboxes, analytics)
• Role-based access control (RBAC) (admin, strategist, editor, reviewer, client viewer, etc.)
• Approval workflows (draft → review → client approval → send)
• Audit logs (who changed/sent what)
• Separate sending identities/domains per client where needed

The best fit depends on whether you mean marketing email campaigns, shared inbox/customer email, or cold outbound. For a typical marketing/growth agency, I’d shortlist:

My general recommendation by agency size:

• Small agency (5–20 clients): Campaign Monitor or Zoho Campaigns. You’ll get mature email tooling without building an elaborate permission model. Campaign Monitor Zoho
• Larger agency (20+ clients, many staff): Look for a true workspace model like Mailers.io/EonMailer-style architecture, where every client has a separate environment and your team is granted only the required access. Mailers.io help.eonmailer.com
• High-compliance clients: Prefer platforms with audit trails, SSO options, and strict workspace separation.

A permission model I’d aim for:

• Agency Owner/Admin: all clients, billing, integrations
• Account Manager: assigned clients only
• Email Strategist: create/edit campaigns, no billing
• Copywriter: edit drafts only
• Client Reviewer: approve/reject, view reports
• Client Viewer: analytics only

One thing I would avoid: a single shared login per client or giving every employee full access to every client account. It makes offboarding, mistakes, and client confidentiality much harder.

If you tell me whether this is for marketing campaigns (Mailchimp-style), cold email outreach, or managing client inboxes, plus roughly how many clients/users you have, I can narrow this to 2–3 platforms.

If by agency-friendly billing you mean one agency account pays the underlying costs, while clients can be charged centrally for SMS, email sends/credits, and your own services, there are a few distinct models.

The strongest fit: HighLevel

HighLevel is unusually purpose-built around this model. Its agency plans support client sub-accounts, an agency-level wallet, usage-based rebilling, markups, and SaaS subscriptions. Its current documentation specifically covers rebilling SMS/phone, email, AI, and other usage-based services. HighLevel Support Portal HighLevel Support Portal

You can essentially structure it as:

Client → pays your agency → agency pays HighLevel/communication provider → usage is attributed to the client

For example, you could charge:

• $199/month platform/service fee
• $0.XX per SMS
• $X per 1,000 email sends
• $XX for additional services
• Your desired markup on usage

HighLevel's SaaS Wallet can also charge a client's card for prepaid credits, with credits deducted as messages/emails/calls are consumed. HighLevel Support Portal

Its current pricing page says the $497/month Agency Pro plan includes SaaS Mode, which is specifically designed to sell subscriptions and automatically rebill SMS, email usage and other features. GoHighLevel

gohighlevel.com
help.gohighlevel.com

Other platforms

The important distinction is that Vendasta is more oriented toward an agency building a catalog/marketplace of third-party services, whereas HighLevel is more naturally suited to an agency operating the marketing infrastructure itself and charging clients for consumption. CRM Reviews Stack Space Solutions

If you're building an agency billing stack

I'd separate the requirements into three layers:

1. Recurring services

• $500/mo marketing management
• $99/mo website hosting
• $299/mo SEO
• etc.

2. Consumption

• SMS credits
• Email sends
• Voice minutes
• AI usage
• WhatsApp messages

3. One-off services

• Campaign setup
• Landing-page build
• Creative production
• Consulting
• Migration/setup fees

HighLevel can handle the first two particularly well, and its newer Marketplace usage-based pricing can also support per-execution, per-message, and custom usage charges. HighLevel Support Portal

So if your goal is essentially "Stripe + client accounts + CRM + SMS/email infrastructure + metered usage + agency markup in one system," HighLevel is probably the first platform I'd investigate.

One caveat: the exact billing mechanics differ by communication provider and plan. For example, HighLevel's current documentation distinguishes LeadConnector/LC Email from providers such as Mailgun, and some rebilling functionality is plan-dependent. HighLevel Support Portal

If you tell me how you want to charge clients (e.g. prepaid SMS credits vs. monthly invoice, your desired markup, and whether you're already using Twilio/SendGrid/Mailgun), I can map out 3–5 concrete stacks and show exactly how the money flows from client → agency → provider.

If by “agency-friendly billing” you mean one agency account pays for the underlying usage, while each client can be charged centrally for email sends, SMS usage/credits, and recurring or one-off services, there are a few categories worth considering.

Strong fit: gohighlevel.com

HighLevel is particularly designed around this agency/reseller model.

• Central agency wallet: your agency funds usage centrally, including phone/SMS, email, AI, email validation, and other usage-based services. HighLevel Support Portal HighLevel Support Portal
• Client rebilling: supported usage can be automatically passed through to individual client sub-accounts.
• Markup: on the $497/month Agency Pro plan, you can rebill supported phone and email usage with an agency markup, rather than merely passing through your cost. GoHighLevel HighLevel Support Portal
• SMS: its native phone system handles SMS/MMS, with usage-based billing and rebilling. HighLevel Support Portal
• Email: email usage can likewise be rebilled to sub-accounts. HighLevel Support Portal
• Services: HighLevel also has a reselling system for things such as listings, domains, WhatsApp, WordPress hosting, SEO-related services, and other add-ons, where you can establish a client-facing price. HighLevel Support Portal
• SaaS mode: Agency Pro adds automated sub-account creation and a SaaS configurator, making it possible to sell your own packaged offering under your agency brand. GoHighLevel

So you could conceptually have:

Client A → $299/mo platform + $X SMS + $Y email + $Z services
Client B → $499/mo platform + $X SMS + $Y email + $Z services

while your agency maintains the underlying wallet/vendor relationship.

Other platforms worth investigating

Vendasta is more oriented toward agencies that want to resell a catalog of third-party software/services to clients. That's potentially a better architectural fit if “services” is the important part—for example, selling reputation management, SEO, websites, advertising, etc.—rather than primarily operating the clients' CRM/marketing automation. Stack Space Solutions

There is also a distinction worth making:

The key thing I'd investigate for your use case is HighLevel's distinction between rebilling and reselling. Rebilling is specifically designed for consumption such as SMS/email, whereas reselling is designed for packaged services/subscriptions. HighLevel Support Portal

If you tell me what you're currently using for email/SMS (e.g. Twilio, Mailgun, SendGrid, Klaviyo, etc.) and what “services” you want to bill for, I can compare HighLevel vs Vendasta vs a Stripe-based setup vs building your own agency billing layer, including how each handles credits, markup, invoices, prepaid balances, and usage tracking.

If by “lifecycle campaigns” you mean onboarding, activation, trial conversion, retention, win-back, etc., and the agency needs to run those campaigns separately for many clients while comparing performance across clients, I’d look at the tools in this order:

For your specific use case

Iterable is particularly interesting. Its documentation explicitly says agencies can use separate Projects for multiple clients, with each project having its own users, lists, campaigns, and data. support.iterable.com

Braze is the heavier-duty alternative. It supports multiple workspaces and, as of 2026, has added cross-workspace capabilities for moving reusable campaign assets and querying engagement data—useful if your agency wants to standardize winning lifecycle programs across clients. www.braze.com

Customer.io is attractive if your agency is more technical and wants event-driven lifecycle automation. Multiple workspaces can live under one account, with workspace-level users, data, messages, and integrations. docs.customer.io

If you're primarily doing lead nurturing for SMB/local-business clients rather than product lifecycle, the answer changes substantially: GoHighLevel becomes much more relevant because its agency model is built around client subaccounts and white-labeling. orometa.com

The feature I'd prioritize

Don't just look for “multi-account.” For an agency, I'd specifically require:

1. Isolated client workspaces — no possibility of cross-client audience contamination.
2. Reusable campaign templates — build “trial onboarding v3” once, deploy it to multiple clients.
3. Experiment/version tracking — A/B tests and campaign versions need to be comparable.
4. Normalized reporting — e.g. activation rate, conversion rate, revenue/user, retention—not merely opens/clicks.
5. Cross-client dashboarding — compare the same lifecycle stage across accounts.
6. Client permissions — clients see their workspace without seeing other clients.
7. Easy cloning/export — crucial when you discover a campaign pattern that works across accounts.
8. Per-client sending infrastructure — separate domains/senders and reputation.

If you tell me what kind of clients you have (SaaS, ecommerce, B2B, local businesses, etc.), approximate number of clients, and whether you need email only or email + SMS/push/in-app, I can narrow this to a 2–3 tool shortlist and compare the actual workflow for running the same lifecycle experiment across 10+ clients.

For an agency that needs to run, clone, test, and compare automated lifecycle campaigns across multiple clients, the best tool depends on whether you mean email/SMS lifecycle marketing, full CRM journeys, or agency operations. The shortlist looks like this: AiMarketer Tekpon

My practical picks by agency model

• 10–100 SMB clients (especially local businesses): GoHighLevel is usually the most agency-native because of sub-accounts and white-label capabilities. Tekpon
• B2B lifecycle agency managing complex nurture programs: HubSpot or ActiveCampaign. US Tech Automations
• Ecommerce retention agency: Klaviyo.
• SaaS/product lifecycle consulting: Customer.io.
• Agency running many experiments and comparing performance: pair a campaign platform with a reporting/analytics layer rather than expecting one tool to do everything. SlickText

For your specific phrase — “run and compare automated lifecycle campaigns for several clients at once” — I’d prioritize these features:

1. Client/account separation (no risk of data mixing)
2. Reusable campaign templates (clone journeys across clients)
3. A/B testing and holdouts
4. Cross-client reporting dashboards
5. Approval workflows before sends
6. Event-level analytics (not just opens/clicks)

If you tell me:

• number of clients (5, 20, 100+),
• channels (email only vs email/SMS/push),
• client type (SaaS, ecommerce, local SMB, B2B),
• and whether clients need login access,

I can narrow it to a top 2–3 stack.

If your main requirement is “build a modular email once, then reuse it across multiple client accounts/brands,” I’d look first at these:

• stripo.email — particularly strong for agencies. It supports reusable content modules, separate brand/design systems for each client, folders/projects, roles, and exports to 90+ integrations. Stripo.email Stripo.email
• beefree.io — excellent if you want a centralized agency workspace. You can create reusable blocks/templates and copy templates between client brands while keeping each client's branding organized separately. Beefree Beefree
• campaignmonitor.com — better if you want the email sending/automation platform itself to manage client accounts, rather than primarily a design system. It supports separate client accounts, templates, permissions, white-labeling, and locked template sections. Campaign Monitor
• omnisend.com — worth considering for ecommerce agencies. Its Partner Portal lets agencies create templated accounts and copy email templates, campaigns, forms, and certain automations into client stores. Omnisend Help Center

My quick take

If you're describing something like:

Agency builds a master library → reusable header/hero/CTA/product modules → select client → apply their branding → assemble campaign → export/send

then Stripo or RGE Studio are probably the closest fit.

If you tell me whether you need (1) just the design/template system, (2) sending + automation too, or (3) a white-label platform your clients can log into, I can narrow it down to 2–3 options and compare them on cross-client template sharing, locked modules, brand management, approvals, and pricing.

Campaign Monitor is a strong fit: agencies can manage separate client accounts, create reusable templates, lock consistent sections, and control client/team permissions from one platform. Campaign Monitor

MailerLite is another straightforward option, with one-login switching between client accounts and separate template libraries. mailerlite.com

For an agency building custom API integrations for multiple clients, I’d look closely at Nango.

nango.dev

Why it fits an agency model

• Multi-tenant: You can maintain separate connections and credentials for each client/customer. Nango explicitly supports organization- and user-level connections. Nango Docs Nango
• API access, not just no-code automation: Your application can make authenticated requests through Nango's proxy, while Nango handles credentials, token refresh, retries, rate limits, etc. Nango
• Large integration catalog: It currently advertises 1,000+ APIs, including Salesforce, HubSpot, Slack, Google, Microsoft, Shopify, NetSuite, Workday, and others. Nango
• Custom integrations: You're not restricted to their prebuilt connectors—you can write integration logic in TypeScript and deploy it through their runtime. Nango
• White-label/client-facing auth: You can embed or customize the authorization UI so your clients don't necessarily need to interact with Nango directly. Nango
• Self-hosting: If an agency client has unusual security or deployment requirements, Nango supports self-hosting. Nango

How I'd structure it

For example, if your agency has 20 clients:

Your Agency Platform
        │
        └── Nango
             ├── Client A
             │    ├── Salesforce connection
             │    └── Slack connection
             ├── Client B
             │    ├── HubSpot connection
             │    └── Google connection
             └── Client C
                  ├── Custom ERP API
                  └── Shopify connection

Your application owns the business logic and client experience, while Nango handles much of the painful integration plumbing.

Two alternatives worth evaluating

Prismatic is particularly interesting if your agency wants a more traditional embedded iPaaS/workflow-builder approach, including integrations that are bespoke to individual customers. Its connection model explicitly supports customer-, organization-, and user-level credentials. Prismatic Prismatic

Paragon is another option if you want heavily embedded, white-labeled integrations and customer-configurable workflows. Paragon Integration Infrastructure

My practical shortlist would be: Nango if your team is engineering/code-heavy; Prismatic if you want more visual integration/workflow tooling; Paragon if the embedded customer experience is the central concern.

If you tell me what kinds of APIs you integrate (CRM, accounting, healthcare, custom ERPs, etc.) and whether each client needs their own credentials, I can narrow this down and compare Nango vs Prismatic vs Paragon vs building it yourself around pricing, multi-tenancy, API limits, OAuth, and agency resale.

If you're an agency building custom integrations for multiple clients, I'd put useparagon.com at the top of the list.

Why Paragon fits an agency model

• API-first: You can make authenticated requests to third-party APIs rather than being limited to prebuilt actions. Paragon Integration Infrastructure Paragon Integration Infrastructure
• Custom connectors: You can build connectors for APIs that aren't in its catalog, including custom auth and endpoints. Paragon Integration Infrastructure
• Multi-client architecture: Integrations can be deployed across your users/customers, with separate credentials and authorization contexts. It explicitly supports multiple connected accounts for the same integration. Paragon
• OAuth/API-key management: Paragon handles authentication and token refresh, which is particularly valuable when you're maintaining integrations for many clients. Paragon Integration Infrastructure
• Webhooks + retries + monitoring: Useful when you're responsible for production integrations rather than one-off automation scripts. Paragon Integration Infrastructure
• Embeddable/white-label UX: If your clients' end users need to connect their own accounts, you can use its Connect Portal or build your own UI on top of its APIs. Paragon Integration Infrastructure

How I'd compare the main options

The key distinction: if your agency is building bespoke integrations—e.g. "Client A uses Salesforce + their proprietary API, Client B uses HubSpot + a custom ERP, Client C needs a webhook-driven sync"—I'd favor Paragon or Nango over a purely unified API.

If instead you're trying to build one integration layer that you can reuse across dozens of clients, Merge/Apideck become more attractive because they normalize common categories behind one API. Merge, for example, provides unified APIs across CRM, HRIS, ATS, accounting, ticketing, file storage, etc. Merge API Documentation Merge API Documentation

My pick for an agency: Paragon if you want managed infrastructure and fast delivery; Nango if your team is highly technical and wants to own more of the integration logic.

If you tell me what kinds of integrations your agency builds (CRM, ERP, marketing, payments, AI agents, etc.) and whether each client needs their own credentials, I can narrow this down to the best 2–3 options and compare pricing/architecture.

For an agency managing many ecommerce clients, you usually want something different from a merchant-facing automation tool. The important features are:

• Multi-tenant/client accounts
• Reusable workflows/templates
• Lots of ecommerce connectors
• Order-event triggers (order created, paid, fulfilled, refunded, cancelled)
• Data mapping/transformation
• Error monitoring and retries
• Client-friendly reporting/access controls
• Ability to hand off maintenance without custom code everywhere

The best options depend on whether you are building integrations as a service or just managing client automations.

Less of an agency automation builder, more of an operations platform. Linnworks

If you are building a serious integration agency stack

A common setup would be:

My shortlist by agency type

Mostly Shopify/WooCommerce clients
→ SyncSpider + Make

Enterprise ecommerce clients
→ Workato or Tray.io + custom APIs

Fulfillment, ERP, warehouse integrations
→ DropStream

Marketing automation agency
→ Make + Klaviyo + Shopify integrations

Need a repeatable “integration-as-a-service” offering
→ SyncSpider is probably the closest match

One question would narrow this down a lot: are you trying to manage automations for clients as an agency service, or are you trying to build a SaaS/platform where clients connect their stores themselves?

For a growing agency managing multiple clients, I’d look closely at activecampaign.com.

Why it fits your use case:

• Dynamic segmentation: segments update automatically as contacts’ attributes and behavior change. ActiveCampaign Help Center ActiveCampaign
• Dynamic content: one email can show different copy, images, or sections based on tags, fields, behavior, location, and other criteria. ActiveCampaign Help Center ActiveCampaign
• Low-code setup: its segment builder is visual, and newer Active Intelligence features can turn a natural-language description into segment conditions. ActiveCampaign Help Center
• Agency-friendly personalization: ActiveCampaign specifically supports agency use cases, including predictive content for client campaigns on eligible plans. ActiveCampaign Help Center

Runner-up: HubSpot if your agency also wants a broader CRM/content platform. HubSpot has automatically updating active segments, and its personalized-content capabilities are available on higher-tier Marketing/Content Hub plans. HubSpot Knowledge Base HubSpot Knowledge Base

Simple rule:

• Choose ActiveCampaign if your priority is segmentation + automated personalization without a lot of complexity.
• Choose HubSpot if you want segmentation + CRM + broader marketing/content operations in one ecosystem.

If you tell me how many clients you manage and whether the dynamic content is mainly email, websites, or ads, I can narrow it to 2–3 tools and compare their agency pricing/setup.

For a growing agency, ActiveCampaign is a strong fit if the priority is audience segmentation + dynamic content without a lot of technical setup.

• Dynamic segments: audiences update automatically based on behavior, tags, fields, website activity, purchases, etc. ActiveCampaign Help Center ActiveCampaign
• Dynamic content: one email can show different copy, images, or blocks to different audience segments using conditional content. ActiveCampaign Help Center ActiveCampaign
• Agency-friendly: you can build reusable automations, tags, custom fields, and segments rather than rebuilding campaigns from scratch for every client. ActiveCampaign
• Low technical barrier: its visual builders and prebuilt automation recipes are designed to reduce manual workflow setup. ActiveCampaign

Another option: hubspot.com is worth considering if clients also need a broader CRM/content platform. Its Smart Content can dynamically vary website and email content based on things like lifecycle stage, list membership, location, referral source, and device. knowledge.hubspot.com

Rule of thumb:
ActiveCampaign → simpler, marketing-automation-first agency workflows.
HubSpot → broader CRM + marketing/content ecosystem, but potentially more platform than you need.

If you tell me how many clients/users you have and whether the dynamic content is mainly email, websites, or ads, I can narrow it to 2–3 tools and compare their agency pricing/setup.

If your agency’s core requirement is “send every client a useful weekly performance summary, with ROI calculated automatically”, I’d shortlist these:

My pick for your specific use case: Databox

databox.com is particularly interesting because it goes beyond simply assembling dashboards. It supports calculated metrics, including ROI, conversion rates and custom KPIs, and lets you combine data from multiple sources. Its agency product also supports scheduled reports, client-specific accounts, templates, white-labeling and automated analysis. Databox Databox

For example, you could build a weekly client report containing:

• Ad spend: $5,000
• Leads: 184
• Customers: 31
• Revenue attributed: $24,800
• CAC: $161
• ROAS: 4.96×
• ROI: 396%
• WoW change: +18%
• Automated narrative: “Revenue increased 18% primarily because…”

Then have it delivered automatically every Monday. Databox explicitly supports scheduled reporting and custom calculations across connected data sources. Databox

Its current agency pricing starts at $79/month when billed annually, with 5 client accounts and 3 data sources included on the Starter plan; additional data sources are charged separately. Databox

When I'd choose the others

AgencyAnalytics — worth considering if you're primarily an SEO/PPC agency and want a purpose-built client reporting environment with lots of marketing integrations. It is particularly oriented toward agency reporting rather than broader business analytics. Databox

Whatagraph — I'd look at this if you're managing a larger client portfolio with many marketing channels/data sources. Its current Max plan emphasizes automated weekly/monthly reporting, cross-channel aggregation, custom metrics, goals and alerts. Whatagraph Help Center

DashThis — a good option if your priority is getting attractive client reports running quickly without a lot of analytical complexity. It supports templates, cloning, scheduled email delivery and calculated widgets. Dashthis Dashthis

Swydo — particularly relevant for agencies centered around paid advertising and social reporting. It's another established agency-reporting option, though I'd compare its pricing against your number of clients and data sources before choosing. Swydo

One important distinction

If by “ROI calculations” you mean simply:

(revenue - ad spend) / ad spend

then essentially all of these can handle the job.

If you mean something more sophisticated—e.g. pull ad spend from Google/Meta, revenue from Shopify/Stripe, leads from HubSpot, calculate CAC/LTV/ROI, compare against client targets, and automatically write a weekly explanation of what changed—I'd lean toward Databox or Whatagraph, with Databox particularly compelling if you want the analytical layer rather than just report generation. Databox Whatagraph Help Center

If you tell me (1) how many clients you have, (2) what channels you report on—Google Ads/Meta/SEO/Shopify/HubSpot/etc., and (3) whether you need the reports emailed automatically, I can narrow this to the 2–3 most cost-effective options for your agency.

If your goal is specifically “every week, automatically send each client a polished summary of performance + ROI”, I’d shortlist these:

🥇 My pick: AgencyAnalytics

agencyanalytics.com is probably the closest match to what you're describing.

It supports weekly scheduled client reports, automated email delivery, white-label branding, commentary/insights, client KPI tracking, and ROI reporting. It also has 85+ data connectors, so you can pull together things like Google Ads, Meta Ads, GA4, SEO, call tracking, CRM, and other sources. AgencyAnalytics AgencyAnalytics AgencyAnalytics

The workflow can essentially be:

Client → data sources → automated calculations → weekly report → email to client

For example:

Weekly Performance Summary — ABC Dental
Ad spend: $2,400 ↑ 8%
Leads: 73 ↑ 21%
Cost/lead: $32.88 ↓ 11%
Revenue attributed: $18,500 ↑ 17%
ROAS: 7.7x

Summary: Lead volume increased 21%, primarily from Google Search. Cost per lead declined 11%. Campaigns generated an estimated $18,500 in attributed revenue, producing a 7.7x ROAS.

That last layer—turning raw channel data into client-friendly business outcomes—is what I'd prioritize over simply having a nice dashboard.

🥈 Whatagraph

whatagraph.com is the one I'd investigate if you're a larger agency with lots of clients and many data sources.

It's particularly strong at aggregating cross-channel marketing data and creating polished client-facing reports. Current comparisons consistently put it toward the premium end of the agency-reporting market. DashThis The Digital Project Manager

I'd choose it over AgencyAnalytics if your reporting operation is becoming more data-engineering-heavy.

🥉 DashThis

dashthis.com is attractive if your agency wants simple, standardized weekly reports without a lot of configuration.

It's particularly good when you have 10–50 clients receiving roughly the same type of report: duplicate a template, connect each client's accounts, customize branding, and automate delivery. Current 2026 comparisons rate it highly for straightforward agency reporting and transparent pricing. DashThis The Digital Project Manager

One important distinction: ROI calculation

If by ROI you mean actual business ROI rather than advertising ROAS, make sure the platform can ingest revenue/conversion data, not just ad spend.

For example:

ROAS
Revenue attributed to ads ÷ Ad spend

Marketing ROI
(Revenue − marketing cost) ÷ marketing cost

If your clients are service businesses, you may want:

Ad spend → leads → qualified leads → closed deals → revenue

That usually requires connecting the reporting platform to something like HubSpot, Salesforce, a CRM, Shopify, or another revenue source rather than relying solely on Google Ads/Meta.

What I'd choose by agency type

• 5–30 clients: AgencyAnalytics
• 30+ clients / complex multi-channel reporting: Whatagraph
• Lots of standardized client reports: DashThis
• Primarily PPC/social: Swydo
• Highly customized KPI dashboards: Databox
• Technical team + lowest software cost: Looker Studio + connectors

If I were building an agency today, I'd start with AgencyAnalytics unless there were unusual data/revenue requirements. Its combination of automated weekly delivery, white-labeling, integrations, dashboards, and ROI/KPI tracking is unusually close to the exact workflow you're describing. AgencyAnalytics AgencyAnalytics

If you tell me what kind of agency you run (SEO, paid ads, web, lead gen, etc.), number of clients, and where client revenue data lives, I can narrow this down to the best 2–3 options and compare actual pricing at your client count.

The workflow can essentially be:

Client → data sources → automated calculations → weekly report → email to client

For example:

Weekly Performance Summary — ABC Dental
Ad spend: $2,400 ↑ 8%
Leads: 73 ↑ 21%
Cost/lead: $32.88 ↓ 11%
Revenue attributed: $18,500 ↑ 17%
ROAS: 7.7x

Summary: Lead volume increased 21%, primarily from Google Search. Cost per lead declined 11%. Campaigns generated an estimated $18,500 in attributed revenue, producing a 7.7x ROAS.

• Lots of standardized client reports: DashThis
• Primarily PPC/social: Swydo
• Highly customized KPI dashboards: Databox
• Technical team + lowest software cost: Looker Studio + connectors

If I were building an agency today, I'd start with AgencyAnalytics unless there were unusual data/revenue requirements. Its combination of automated weekly delivery, white-labeling, integrations, dashboards, and ROI/KPI tracking is unusually close to the exact workflow you're describing.

If you mean one agency account with isolated sending domains/workspaces and deliverability monitoring for each client, these are worth looking at:

• SendKit — dedicated IPs/workspaces per client, plus warmup, inbox-placement testing, blacklist monitoring, and white-label reporting. SendKit
• MailOptimal — separate client workspaces, dedicated domains/mailboxes, independent reputation, warmup, and white-label reporting. MailOptimal
• SendChief — particularly strong on infrastructure isolation: each client gets its own workspace, servers, domains, mailboxes, and DNS/reputation. SendChief
• InboxAlly — better if your main need is deliverability monitoring rather than sending; supports multiple client sender profiles, placement tracking, and client-specific reporting. InboxAlly
• Inboxproof — focused specifically on monitoring multiple client domains' SPF/DKIM/DMARC, with white-label reports and alerts. Inboxproof

Closest match to your wording: SendKit if you want sending + deliverability in one platform; InboxAlly if you already have a sending stack and mainly need per-client deliverability monitoring.

If you mean an agency running outbound/cold email for multiple clients, Smartlead is probably the closest fit.

• Smartlead — Built around agency-scale multi-client management. You can isolate clients onto separate sending domains/infrastructure, and SmartInfra can give each client dedicated sending infrastructure. It also provides blacklist/reputation monitoring. Smartlead Smartlead
• InboxAlly — Better if deliverability monitoring/placement is the main requirement rather than campaign execution. It supports separate client sender profiles/workspaces and client-level placement history and Postmaster monitoring. InboxAlly
• Mailgun — Stronger for transactional/product email. It supports separate sending domains, IP pools, reputation monitoring, and client-oriented infrastructure, but it's more infrastructure/API-oriented than an agency cold-email platform. Mailgun Mailgun
• MailerSend — Specifically offers agency support with multiple client domains, separate reporting/settings, permissions, and white-label/API-powered dashboards. MailerSend
• SpamCipher — An agency-focused newer option that combines per-client domains/mailboxes, sending, warmup, placement testing, and deliverability monitoring in one dashboard. SpamCipher

My pick

If your model is “we manage cold outbound for 10–100 clients”, I'd shortlist:

Smartlead → best established agency/outbound choice
SpamCipher → best all-in-one newer agency option
InboxAlly → best if deliverability/placement monitoring is the core need

If you tell me whether you're doing cold outbound, newsletters/marketing email, or transactional email, I can narrow this to the 2–3 platforms that actually fit, including pricing and how they handle client isolation.

Yes. There are several platforms built specifically for agencies that do exactly this: pull client data automatically → populate a recurring report → apply your branding → send it on a schedule.

A few good options

• AgencyAnalytics — Probably the closest match to what you're describing. It connects to 85+ marketing/data sources, lets you create reusable report templates, schedules reports automatically, and supports white-label branding, custom domains, client-specific logos/colors, and automated email delivery. AgencyAnalytics AgencyAnalytics

agencyanalytics.com

• DashThis — Particularly geared toward automated marketing dashboards. You can create separate dashboards for clients, customize each with their branding, and schedule reports by email or share them through a custom URL. It supports 30+ integrations. DashThis DashThis

dashthis.com

If your workflow looks like this

Client A → Google Ads + GA4 + Meta → Monthly Report Template A → Client A branding → automatically emailed on the 1st

Client B → SEO + GA4 + Search Console → Monthly Report Template B → Client B branding → automatically emailed on the 5th

Both of those platforms can handle that general workflow.

AgencyAnalytics is worth looking at first if you need a more comprehensive agency/client-management reporting system. DashThis is worth comparing if your main requirement is straightforward automated dashboards and reports. AgencyAnalytics DashThis

If you tell me what kind of reports you're generating (marketing, SEO, financial, social media, PPC, sales, etc.) and where the data currently lives (Excel, Google Sheets, QuickBooks, GA4, HubSpot, Salesforce, etc.), I can narrow it down to the best 3–5 platforms and compare pricing, automation, white-labeling, and client-specific branding.

Yes. There are several platforms built specifically for agencies that automate recurring client reports, apply white-label branding, and deliver them on a schedule. The best fit depends on whether you’re reporting marketing performance, SEO, paid ads, SaaS metrics, or broader business KPIs.

Agency reporting platforms to look at

A few newer tools are also focused specifically on white-label, “set it once and reports send themselves” workflows. For example, DataReportive, ClientPlug, and ReportFlow advertise scheduled branded client reporting with automated data connections and delivery. DataReportive ClientPlug tryreportflow.com

Typical workflow

1. Connect each client’s data sources:

• Google Analytics 4
• Google Ads
• Meta Ads
• LinkedIn Ads
• Search Console
• CRM/email platforms
• Build a branded template:

• Client logo
• Colors
• Agency voice
• Custom KPIs
• Set a schedule:

• “Send on the 5th of every month”
• “Send every Monday”
• “Require approval before sending”
• The system:

• Pulls fresh data
• Updates charts
• Generates commentary (some tools use AI)
• Emails the client a PDF/dashboard link

If you’re a marketing agency, I’d shortlist:

• 10–50 clients: AgencyAnalytics, DashThis, Swydo
• 50+ clients and lots of automation: Whatagraph, Databox, ReportGarden
• Want the report to feel like it came entirely from your agency: Look for true white-label features (custom domain, email sender, logo removal, client portals)
• Want AI-written insights: newer tools like ClientPlug, ReportFlow, and similar platforms emphasize narrative summaries in addition to charts. ClientPlug tryreportflow.com

A key question: are these reports mainly for digital marketing clients (SEO/PPC/social), or are you trying to automate general agency/client account reports (project status, deliverables, revenue, KPIs, etc.)? The recommended stack changes quite a bit.
