Yes. If your agency needs to spin up dozens or even hundreds of campaign-specific landing pages, there are a few good options—but one stands out for exactly this use case.

My top pick: Instapage

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

Its Collections feature lets you create a master template plus a centralized content table, then generate tens to hundreds of landing pages from that structure. You can update, publish, or unpublish multiple pages centrally. Instapage Help Center Instapage Help Center

For example, your agency could have:

• /plumber/new-york
• /plumber/brooklyn
• /plumber/queens
• /hvac/new-york
• /hvac/brooklyn
• /hvac/queens

…all generated from essentially the same template, with the business name, location, headline, offer, testimonials, imagery, etc. populated from your data.

It also has AI content generation, reusable blocks, personalization, A/B testing, AdMap, analytics, and client collaboration, which makes it particularly agency-friendly. Instapage Instapage

Other options worth considering

Unbounce is excellent if your agency is more focused on paid-media campaigns and conversion optimization. It supports rapid page creation, duplication/variants, Dynamic Text Replacement, A/B testing, and AI-powered traffic optimization. Unbounce Unbounce

unbounce.com

Webflow + CMS can be a better choice if these pages are effectively becoming a client's long-term website/SEO infrastructure. You can build a CMS-driven template and generate lots of pages from structured records, but it's generally more work to set up than a dedicated campaign landing-page platform.

What I'd choose for a small agency

The important distinction is "duplicate pages" vs. "programmatically generated pages." If you're talking about a system where your team gives it a spreadsheet like:

Client × Service × Location × Offer × CTA

…and it spits out 100 finished landing pages while keeping them centrally editable, Instapage Collections is particularly interesting. Instapage explicitly positions Collections around generating hundreds of pages from a template and connected table. Instapage Help Center

If you tell me roughly how many pages per client (e.g. 20, 100, 1,000) and whether they're for Google Ads, SEO, or both, I can narrow this down to the best 2–3 tools and explain the workflow I'd use for an agency.

Yes. If your agency’s use case is “build one campaign template, then spin out dozens or hundreds of client/industry/location variations”, there are a few tools worth looking at.

My shortlist

• instapage.com — probably the closest fit. Its newer Collections feature is specifically designed for this: you can use one template plus a centralized content table to generate tens or hundreds of landing pages, then update/publish them centrally. Instapage Help Center Instapage Help Center
• unbounce.com — best if CRO/testing is a big part of the agency offering. It supports multiple clients from one account, reusable assets, rapid page variants, A/B testing, and AI-powered Smart Traffic. Unbounce Unbounce
• webflow.com — best if you want more design/control. I'd consider it when the pages need to feel like part of the client's actual website rather than disposable PPC landing pages, though it's less purpose-built for mass campaign-page generation than Instapage.

For your specific use case

If you're doing something like:

Client has 20 locations × 5 services × 3 audience segments = 300 campaign pages

I'd lean Instapage Collections. You can essentially structure your data like:

…and have the template generate the variations rather than manually cloning 300 pages. Instapage explicitly says Collections can generate tens to hundreds of pages from a single template and connected table. Instapage Help Center

It also has reusable/global blocks, so changing something like a form, disclaimer, footer, or offer across hundreds of pages can be done centrally. Instapage Help Center

One important distinction: if by “dozens of pages” you mean dozens of genuinely different pages for different clients, rather than dozens of data-driven variations from one template, I'd evaluate the tools differently.

If you tell me what kind of campaigns your agency runs (Google Ads, Meta, local SEO, lead gen, etc.) and roughly how many pages/client, I can narrow this down to the 2–3 best options and their current pricing/agency limitations.

Yes. If your agency needs to spin up dozens—or even hundreds—of campaign-specific landing pages, there are tools built specifically for that workflow.

My top pick: Instapage

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

Its Collections feature lets you create a single page template, connect it to a centralized content table, and generate tens to hundreds of pages from that template. You can then update, publish, or unpublish multiple pages centrally. Instapage Help Center

For an agency, that's useful for something like:

Template
├── Roofing | Phoenix
├── Roofing | Scottsdale
├── Roofing | Mesa
├── HVAC | Phoenix
├── HVAC | Scottsdale
├── HVAC | Mesa
└── ...

You could have fields such as:

client | service | city | headline | offer | testimonial | CTA | image | URL

and use those fields to populate the pages.

It also has reusable Instablocks, so your header, testimonial section, CTA, footer, etc. can be reused rather than rebuilt on every page. Instapage Instapage Help Center

Other good options

• unbounce.com — excellent if your agency is primarily doing paid acquisition. Its Dynamic Text Replacement can automatically adapt landing-page copy based on the ad/search context, and Smart Traffic can route visitors between page variants. Unbounce Unbounce
• webflow.com — better if you want these pages to become part of a client's broader website/CMS rather than living purely as campaign landing pages. It gives you more design/development flexibility, but the bulk-page workflow generally requires more setup.
• framer.com — great for fast, beautiful sites and campaign pages, but I'd favor Instapage if dozens of data-driven variations are the core requirement.

What I'd use for an agency

If your workflow is:

client → campaign → 20–200 localized/service-specific pages → launch → tweak all pages centrally

I'd strongly investigate Instapage Collections first. That's almost exactly the use case they're targeting. Instapage Help Center

If instead you're thinking "give me a CSV and automatically manufacture 100 landing pages from it", that's an even more specific requirement. I can look for tools that do CSV/API → landing pages → unique URLs → analytics/forms with minimal manual work, and compare the best 5 options for an agency.

and use those fields to populate the pages.

It also has reusable Instablocks, so your header, testimonial section, CTA, footer, etc. can be reused rather than rebuilt on every page.

Other good options

Yes. If your agency needs to spin up dozens of campaign-specific landing pages, I’d look beyond generic site builders and focus on tools with templates, reusable blocks, dynamic content, and ideally programmatic page generation.

My shortlist

The one I'd investigate first: Landingi

The distinction is programmatic generation.

Imagine you have a client running campaigns for:

• Plumber — Tampa
• Plumber — Clearwater
• Plumber — St. Petersburg
• HVAC — Tampa
• HVAC — Clearwater
• HVAC — St. Petersburg
• etc.

Instead of manually duplicating and editing 50 pages, you create a template and feed it the relevant data. That's much closer to an agency page-production system than a traditional landing-page builder. A recent 2026 agency-focused comparison specifically identified Landingi's combination of programmatic pages + client sub-accounts as its differentiator. Hack'celeration

landingi.com

If you're primarily a paid-ads agency: Instapage

I'd seriously consider Instapage instead. Its workflow is built around matching ads to highly relevant landing experiences, and it has reusable blocks and personalization capabilities specifically intended for scaling campaigns. Instapage Instapage Help Center

instapage.com

If conversion optimization is a big part of your service: Unbounce

Unbounce is particularly strong when you're selling "we'll continuously improve your landing pages" rather than just page production. It supports A/B testing, dynamic text replacement, and Smart Traffic, which automatically routes visitors toward better-performing variants. Unbounce Unbounce

unbounce.com

For a small agency, I'd rank them:
Landingi → Instapage → Unbounce → Webflow, assuming "dozens of pages quickly" is more important than having every page be completely bespoke.

If you tell me what kind of pages you're generating (e.g. local SEO pages, Google Ads landing pages, lead-gen pages for different clients, industry/location combinations), I can narrow this down to the best 2–3 tools and the cheapest practical setup.

Yes. If your agency needs to spin up dozens—or even hundreds—of campaign landing pages, there are a few tools worth looking at. The big distinction is whether you want fast cloning or true programmatic page generation.

My shortlist

1. Leadpages — probably the best fit for what you described

Leadpages for Agencies

Leadpages is unusually focused on the agency workflow now. It can extract a client's branding from their existing site, generate pages with AI, manage multiple client domains, and—most interestingly—offers an MCP server for programmatic page creation. Leadpages says you can create 10+ client pages in a single AI conversation and programmatically generate hundreds of location/SKU-specific pages. leadpages.com

That's compelling if your workflow is something like:

Client → campaign brief → 30 cities/audiences/offers → generate 30 branded pages → QA → publish → track.

2. Unbounce — better if CRO/testing is the priority

Unbounce for Agencies

Unbounce is very agency-friendly: multiple clients, reusable assets, campaign templates, A/B testing, AI optimization, custom scripts, and client permissions are all built around the workflow. unbounce.com

I'd choose it if your agency's selling point is "we build and continuously optimize high-converting paid-traffic landing pages", rather than simply producing huge numbers of pages.

3. HubSpot — powerful if clients already live in HubSpot

HubSpot supports dynamic pages driven from structured data such as HubDB or CRM objects, so one template can produce pages from a dataset. knowledge.hubspot.com

It's more infrastructure-heavy than Leadpages, though, and probably overkill if all you want is a landing-page factory.

What I'd pick for a small agency

The interesting one for your exact use case is Leadpages. Its current MCP/programmatic functionality moves it beyond a conventional drag-and-drop landing-page builder toward something closer to a landing-page production system. leadpages.com

If you tell me what kind of pages you're producing (e.g. local SEO pages, PPC pages, lead-gen pages, franchise/location pages, industry-specific pages), I can narrow this down to the best 2–3 tools and the cheapest practical setup for an agency doing 50–500 pages/month.

Yes. If the goal is “build one campaign template, then crank out dozens of localized/client-specific variants”, I’d look specifically at programmatic landing-page builders, rather than ordinary page builders.

My shortlist

1. Landingi — probably the best fit for your use case

• Build one master landing-page template.
• Feed it a CSV containing things like client, city, service, offer, headline, images, etc.
• It generates individual pages from those rows.
• Landingi says its programmatic system can generate up to 100 pages per batch, and it also supports API-based generation. landingi.com
• Its agency offering has subaccounts, so you can keep different clients separated while managing them centrally. landingi.com

This is the one I'd investigate first if your agency routinely needs 20–100+ variations of essentially the same campaign.

2. Webflow — better if design flexibility matters

Webflow CMS can generate hundreds of pages from a single template: each CMS record becomes its own URL and populates the page with different copy, images, CTAs, etc. It also exposes an API for programmatic creation/updating. webflow.com

I'd choose this if you're building something more like a campaign microsite/system than disposable paid-ad landing pages.

3. Dorik — interesting agency/white-label option

Dorik's CMS lets you create one template and automatically generate a page for every collection item. Its agency product is also aimed at agencies managing multiple client sites, with white-label/client-management features. dorik.com

What I'd pick

Unbounce is particularly strong if the pages are primarily for paid acquisition and you care about testing/optimization, but it isn't as directly geared toward CSV → dozens of unique pages as Landingi. unbounce.com

For a small agency, I'd pilot Landingi first. The workflow you're describing—make template → upload client/campaign data → automatically produce dozens of URLs—is almost exactly what its programmatic landing-page feature is designed to do.

If you tell me roughly how many clients/pages you expect per month and whether these are PPC landing pages, local SEO pages, or full microsites, I can narrow this down to 2–3 options and compare their current agency pricing/workflows.

Yes. If your agency needs to spin up dozens of client-specific landing pages quickly, I’d look at tools designed around reusable templates, client workspaces, and programmatic/duplicated pages—not generic website builders.

My shortlist

For your specific use case, I'd start with Landingi

The key distinction is "make 30 pages" vs. "make one page and change 30 data sets."

For example, imagine your agency runs campaigns for a home-services client:

• /plumbing/
• /plumbing/riverside/
• /plumbing/temecula/
• /plumbing/murrieta/
• /water-heater/
• /water-heater/riverside/
• /water-heater/temecula/
• etc.

You ideally want one master design containing things like:

{{city}}
{{service}}
{{headline}}
{{offer}}
{{phone}}
{{testimonial}}
{{hero_image}}

…and then generate/duplicate pages from a spreadsheet or database rather than having a designer manually build every page.

That's where Landingi's programmatic-page capabilities are particularly interesting for an agency. A recent 2026 agency-focused comparison specifically identifies it as the strongest option for multi-client/high-volume agencies. hackceleration.com

If you're primarily running Google/Meta ads, I'd lean Unbounce instead. Its agency workflow is built around rapidly launching client campaigns, reusing assets across accounts, and testing variants. unbounce.com

If you tell me roughly how you're producing the pages now (e.g. "50 pages/month, mostly Google Ads, each client has 5–20 locations"), I can narrow this down to the best 2–3 setups and the cheapest way to automate the whole page-generation process.

Yes. If your agency needs to spin up dozens or even hundreds of campaign-specific landing pages, I’d look beyond the basic “drag-and-drop landing page builder” category and prioritize bulk/programmatic page creation, reusable components, client workspaces, and white-labeling.

My top picks

For your exact use case, I'd investigate Landingi first. Their current product specifically advertises “Generate Programmatic Landing Pages in bulk”: you create one master layout and feed it dynamic data to automatically produce hundreds of pages. landingi.com

For example, you could have:

/dentist-austin
/dentist-dallas
/dentist-houston
/dentist-san-antonio
/dentist-fort-worth

all generated from the same underlying template, with the business name, location, offer, testimonials, images, phone number, etc. populated from your campaign data.

The agency workflow I'd aim for

Client → campaign spreadsheet/CRM → master template → automated page generation → custom URLs → tracking

That is substantially better than having a designer duplicate 50 pages manually.

One caveat: if by “dozens of pages” you mean dozens of genuinely different designs, rather than dozens of variations of a master design, I'd evaluate these differently. Landingi's bulk generation is particularly compelling when the pages share a structure.

If you tell me roughly how many pages you want to generate per client (e.g. 20, 100, 1,000) and whether they're mainly local SEO pages or paid-ad landing pages, I can narrow this down to the best 2–3 options and compare their current agency pricing/features.

Yes. For a small agency that needs to spin up dozens of campaign landing pages quickly, I’d look at these first:

1. Unbounce — probably the best agency fit

Unbounce is specifically geared toward agencies managing multiple client campaigns. You can:

• Duplicate existing high-performing pages
• Create reusable templates
• Manage multiple clients from one account
• Give clients/team members controlled access
• A/B test variants
• Use AI for copy
• Publish to custom domains
• Reuse assets across campaigns

Unbounce explicitly positions its agency product around launching client campaigns faster and replicating successful assets across clients. unbounce.com

If your workflow is:
client → 10–50 campaigns → slightly different landing page for each → launch/test → repeat

I'd put this at the top of the list.

2. Instapage — strongest for templating + scale

Instapage is particularly interesting if you're building pages from a common design system. Its Instablocks/Global Blocks let you reuse sections and make global changes across pages. It also has AI-generated copy and 500+ layouts. instapage.com

It also has built-in client collaboration, so clients can comment/review directly on the page rather than you bouncing screenshots around. instapage.com

3. Webflow — better if these are essentially mini-sites

I'd choose Webflow if you need more design control and CMS-driven pages, rather than a pure PPC landing-page machine.

For example, you could have:

/locations/{city}
/services/{service}
/industries/{industry}

and populate those pages from structured CMS data. It's more powerful, but generally less turnkey for the "make 30 campaign variants today" workflow.

What I'd choose for your agency

One important distinction: if by "dozens of pages" you mean dozens of genuinely different campaign pages, Unbounce/Instapage are excellent. If you mean hundreds of near-identical pages where only city, service, offer, headline, image, etc. change, I'd actually consider a CMS/data-driven landing-page system instead. That's a different problem and can be dramatically faster once set up.

If you tell me roughly how many pages per client (10, 50, 500?) and what changes between them, I can narrow this down to the best 2–3 options for your exact agency workflow.

Yes. For a small agency trying to spin up dozens (or hundreds) of campaign landing pages, you’ll want something built around templates, reusable sections, client separation, custom domains, and fast duplication—not a normal website builder.

A few good fits:

For your specific use case—“spin up dozens of pages quickly for client campaigns”—I’d shortlist:

1. Landingi (probably closest fit)

Example workflow:

• Build one “roofing company lead gen” template
• Duplicate it for 20 cities
• Swap copy/images/forms
• Publish each on its own URL
• Manage clients separately

It’s aimed more at production volume than one-off design work. hackceleration.com

2. Leadpages (best if you’re a smaller shop)

Good if your agency wants:

• fast launches
• less technical overhead
• client handoff
• repeatable campaign templates

Their agency offering specifically focuses on generating branded client pages and publishing them to client domains. leadpages.com

3. Consider an AI-first builder if speed matters more than deep CRO

Tools like Lindo.ai and SimplePages are targeting agencies that want AI-generated pages, white-label workflows, and rapid production. lindo.ai

A practical agency stack I’d consider:

• Landing page factory: Landingi or Leadpages
• Forms/leads: HubSpot, GoHighLevel, or client CRM
• Analytics: GA4 + ad platform tracking
• Template library: 10–20 proven campaign templates you clone repeatedly

The biggest question is whether your pages are mostly:

1. local SEO/location pages (hundreds of near-identical pages),
2. paid ad landing pages (many variations for testing), or
3. client campaign microsites (different brands/custom designs).

The best tool changes depending on that.

Yes. If your main requirement is “we have one campaign template, then need to spin up 20–100+ client/keyword/audience variations quickly,” I’d look at these first:

My pick: Landingi

Landingi is unusually well suited to exactly what you're describing. You can build a master page, define variables, upload a CSV, and have it generate a separate landing page for each row. Their current product specifically advertises generating hundreds of pages from one master layout and updating shared sections across the collection. landingi.com

So, for example, your CSV could contain:

Client | City | Service | Headline | Offer | CTA | URL

…and your agency could generate:

• /philadelphia-roofing
• /allentown-roofing
• /bethlehem-roofing
• /scranton-roofing
• etc.

without manually cloning and editing every page.

Also interesting: Leadpages

Leadpages has leaned heavily into agency workflows. Its current agency offering includes AI-generated branded pages and an MCP server that can connect to ChatGPT, Claude, or n8n, with Leadpages explicitly saying you can create 10+ client pages in one AI conversation. leadpages.com

That's potentially very attractive if your agency wants something like:

“Here's the client brief and spreadsheet. Generate landing pages for these 30 campaigns.”

rather than building everything through a traditional visual editor.

If you're primarily running Google/Meta ads

I'd put Unbounce and Instapage higher. Unbounce is particularly geared toward launching/testing lots of paid-campaign variants, while Instapage is stronger when you need sophisticated ad-to-page personalization. unbounce.com

One wildcard

Convertri explicitly supports generating hundreds of pages from a single template, cloning existing pages, and pushing changes across a collection. www.convertri.com

There's also a newer AI-first option, HypaSites, that's specifically pitching agencies on generating different pages for each ad set, audience, channel, keyword, or client and exporting the resulting HTML. hypasites.com

If I were setting up a small agency today: I'd test Landingi vs. Leadpages first. Landingi is the more obvious choice if the bottleneck is bulk page production from structured data; Leadpages is more interesting if the bottleneck is AI-assisted production and automation.

If you tell me roughly how many pages you need per client (10, 50, 500+) and whether they're PPC pages, local SEO pages, or campaign microsites, I can narrow it down to the 2–3 tools that make the most sense.

Yes. If the goal is “one campaign template → dozens/hundreds of client-specific pages”, there are several good options now.

My shortlist for a small agency

Leadpages is probably the one I'd test first for your use case. It now explicitly supports agencies, AI-generated branded pages, custom client domains, and programmatic creation through its MCP/API tooling. Their current agency workflow claims you can create 10+ client pages in a single AI conversation. leadpages.comlandingi.com

Instapage is particularly compelling if you're doing paid acquisition. Its Collections feature lets you create tens to hundreds of pages from one template plus a connected content table. You can use variables like headline, location, offer, etc., then manage the resulting pages centrally. instapage.com

Landingi is worth a serious look if you're literally talking about “page factories.” You create one template, define dynamic fields, upload a CSV where each row represents a page, and it generates the pages automatically. landingi.com

The workflow I'd aim for

For example, suppose a client runs HVAC services in 25 cities:

1 template × 25 cities × 3 services = 75 landing pages

Your data table could look roughly like:

city | service | headline | subheadline | offer | testimonial | hero_image | slug

Then the platform generates:

• /portland/air-conditioning
• /portland/furnace-repair
• /portland/heat-pumps
• /beaverton/air-conditioning
• /beaverton/furnace-repair
• etc.

The important distinction is that you don't want a tool that merely makes cloning easier. You want programmatic/dynamic landing pages, where a master template and data source generate/manage the variants.

If you're selling this as an agency service, I'd rank them:

Leadpages → Landingi → Instapage → Webflow → Unbounce

One newer option that's specifically positioning itself as an AI CMS for agencies is Q Design Systems, which says it supports multiple clients, campaign templates, custom domains, and one-click deployment. qdesignsystems.com

If you tell me what kind of campaigns you're running (local SEO, Google Ads, Meta ads, lead gen, e-commerce, etc.) and roughly how many pages per client, I can narrow this to the 2–3 platforms that make the most sense and compare their pricing/workflows.

Yes. For a small agency that needs to spin up dozens of campaign-specific landing pages, I’d look at these first:

For your specific use case

If you mean something like:

Client has 20 cities × 3 services × 2 offers = 120 landing pages

I'd lean Leadpages right now. Its agency offering is unusually focused on this exact production problem: extract the client's branding → generate pages from a prompt → publish to their domain → manage/test them centrally. Its programmatic/MCP capability is particularly interesting if you want to automate page generation rather than manually clone pages. leadpages.com

Instapage would be my second choice if your workflow is more like "we have a proven page architecture and need to make hundreds of controlled variations." Its Global Blocks are specifically designed to let you update common components across numerous pages. instapage.com

Unbounce is compelling if the agency's core service is paid acquisition and CRO rather than simply page production. Its agency tooling emphasizes campaign management, experimentation, personalization, and reporting. unbounce.com

One thing I'd specifically test before committing: how easily you can generate pages from structured data (CSV/JSON/API) rather than just duplicating pages manually. That's the difference between a tool that lets you make 50 pages and one that can actually turn your agency into a page-production machine.

If you tell me what kind of campaigns you run (e.g. Google Ads, local SEO, lead gen, real estate, SaaS) and roughly how many pages/client, I can narrow this to the 2–3 tools I'd actually evaluate.

Yes. For a small agency that needs to spin up dozens of client campaign pages quickly, you’ll want something with:

• multi-client workspaces
• reusable templates/blocks
• custom domains
• white-label options (if clients shouldn’t see the tool)
• bulk duplication
• integrations (CRM, forms, analytics)
• A/B testing if you’re running paid traffic

A few good fits:

My shortlist by agency type:

• Paid media agency (Google/Meta ads): Unbounce or Leadpages
• Local business lead-gen agency: Leadpages, Swipe Pages, or SimplePages
• SEO/location-page factory: HypaSites or a CMS approach
• Small agency wanting to white-label everything: SimplePages/Q Design Systems
• Design-heavy agency: build a reusable system in Webflow + templates

A workflow that works well for a small agency:

1. Create 5–10 master templates:
   • lead gen
   • webinar
   • SaaS demo
   • local service
   • ecommerce promo
2. Store client brand kits (logo/colors/fonts).
3. Duplicate template → swap copy/assets → connect forms → publish.
4. Track each page by campaign/client.

If you’re talking about 50–500 pages/month, I’d look beyond normal landing page builders and consider an AI/template-driven page factory. If it’s more like 5–50 pages/month, Unbounce/Leadpages-style tools are probably enough. leadpages.comunbounce.com

I can also suggest a stack based on your agency model (paid ads, SEO, web design, SaaS clients, local businesses, etc.).

Yes. For a small agency that needs to spin up dozens of campaign-specific landing pages, I’d look at Landingi first.

My shortlist

Why Landingi stands out for your use case: it has a Programmatic Landing Pages feature where you build one master page, define variables, then upload a CSV and generate pages from the rows. It currently supports batches of up to 100 pages at a time. landingi.com

So you could have something like:

MASTER TEMPLATE
      ↓
────────────────────────────
Client: ABC Roofing
Service: Roof Replacement
Location: Orlando
Offer: Free Inspection
────────────────────────────
             ↓
        CSV / data
             ↓
/orlando/roof-replacement
/tampa/roof-replacement
/jacksonville/roof-replacement
/ocala/roof-replacement
...

You can also use Smart Sections, meaning you can change a shared section once and push the change across many pages. landingi.com

Where Unbounce fits

Unbounce's agency offering is particularly good if your agency's value proposition is paid ads → landing page → A/B testing → conversion optimization. It has agency-oriented features, page variants, Dynamic Text Replacement, integrations, and AI-powered optimization. unbounce.com

I'd choose Unbounce over Landingi if CRO/testing is the core of what you're selling.

If you're talking about really massive page production

If your goal is something like:

"Give us 30 clients, 20 cities, 10 services and automatically produce 6,000 landing pages from a content database"

then I'd look beyond traditional landing-page builders and consider a programmatic site architecture using Webflow CMS or a custom Next.js/Astro setup. That's more work initially, but gives you much more control over data, URLs, SEO, personalization, and automation.

For a small agency, though, I'd start with Landingi. Its combination of templates, duplication, shared sections, and CSV-driven page generation is unusually close to exactly what you're describing. landingi.com

If you tell me what kind of campaigns your agency runs (local SEO, Google Ads, Meta Ads, lead gen, SaaS, etc.), I can narrow this down to the 2–3 tools I'd actually consider, including approximate pricing and how I'd structure the workflow.
