Structure and content, separated
Like a CMS separates themes from posts, we separate email structure from content. Your team edits text, images, and links, not styling, spacing, or code.
A content management system for email campaigns
Manage email content. Not email code.
Modular Mail is a CMS for email. Your templates are set up with defined content areas, and your team fills in the fields to build campaigns. The structure is protected. The brand stays consistent. No code required.
The problem
Email campaigns shouldn't be this hard
01
Stuck with generic templates
Your ESP's drag-and-drop builder is fine for basics, but the emails look like everyone else's. You want custom designs that match your brand, but that means HTML and support from developers.
02
Waiting on technical help
Every campaign needs someone technical to set it up, tweak it, or fix what broke. You're stuck in a queue, waiting for changes that should take minutes.
03
Afraid to touch the code
Maybe you have HTML templates, but you're scared to edit them. One wrong click and the layout breaks, the mobile version is ruined, or the whole thing looks wrong in Outlook.
That's why we built Modular Mail. Your templates are set up with reusable modules and defined content areas. Your team edits what matters. The design never drifts.
How it works
How an email CMS works
The structure is set up once. Your team manages the content.
1. Set up your template structure
Share your brand guidelines, existing templates, or Figma designs. Convert them into a template system with defined modules and content fields, like configuring a CMS theme.
- Use your own developer or agency to set up templates
- Or let our team handle setup as a one-time project
- Custom builds quoted based on complexity
- Your brand guidelines baked into every module
2. Your team manages content
Your team sees content fields: text, images, links, CTAs. They don't see HTML. They select modules, fill in fields, reorder sections, and preview. It's content management, not code editing.
- Edit content fields, not code
- Select and reorder modules with drag-and-drop
- Preview across desktop and mobile instantly
- AI-generated alt text for accessibility
- Structure is protected, content is flexible
3. Export to any email platform
Export production-ready HTML and upload to Mailchimp, Klaviyo, HubSpot, Salesforce, or any ESP. We're a CMS, not an email platform, so there's no vendor lock-in.
- Works with the ESP you already use
- One-click HTML export
- Send tests directly to Litmus, Email on Acid, and other testing tools
- No vendor lock-in, ever
Features
Why Teams Choose Modular Mail
A streamlined way to create and manage HTML email campaigns. Build with reusable modules, keep your brand consistent, and export ready-to-send code for any ESP.
Your template system is configured
Your templates are set up with defined modules and content fields, like configuring a CMS. You start managing content on day one.
Build campaigns in minutes
Drag modules, fill in content fields, reorder sections, and preview. AI suggests alt text for images automatically. If you've used any modern design tool, you'll feel right at home.
Export to any email platform
Modular Mail doesn't lock you into one ESP. Export clean HTML and upload to Mailchimp, Klaviyo, HubSpot, Salesforce Marketing Cloud, or anywhere else.
New modules when you need them
Need a new layout for a product launch or seasonal campaign? We can build additional modules for you, so your template system grows with your needs.
Every email on-brand, automatically
Your colours, fonts, spacing, and structure are baked into the modules. No matter who builds the campaign, it'll look exactly right.
Who it's for
Who uses an email CMS?
Teams who need professional email output without the technical overhead or the risk of things breaking.
Marketing teams without developers
You don't need a developer to publish a blog post. You shouldn't need one to send an email campaign. Once the structure is set up, your team manages the content.
- Professional HTML templates set up for you
- Build campaigns without any technical knowledge
- No more waiting on dev for content changes
Agencies who hand off to clients
You build templates for clients. Modular Mail lets you convert them into a managed content system. Clients edit content fields, your structure stays protected. Set up templates yourself or let us handle it.
- Build each client's template library once
- Let clients self-serve campaign creation
- Protect your work with structured modules
Teams with templates they can't use
You've got perfectly good templates sitting unused because they're 'just HTML.' Modular Mail makes them editable—without rebuilding anything. Your team gets a visual editor; your templates stay exactly as designed.
- Unlock existing templates without rebuilding them
- Marketing edits content; design stays locked
- Brand-safe output every time
We used to wait 3-5 days for dev to update our email templates. Now my team builds campaigns in an afternoon. Same custom designs, zero technical dependency.

FAQ
Frequently asked questions
Everything you need to know about getting started with Modular Mail.
Do I need a developer to use Modular Mail?
Not for day-to-day use. Once your templates are set up, your marketing team can build campaigns without any technical knowledge. For the initial setup, you can either use your own developer or agency, or we offer professional template conversion as a project-based service.
What if I don't have email templates yet?
That's fine. We offer professional template development as a service, building your template system from scratch based on your brand guidelines or reference designs. We also offer Figma-to-HTML conversion. Pricing depends on complexity. Contact us for a quote.
How much does template setup cost?
It depends on who does it. If you have a developer or agency, they can set up your templates directly and you just pay the monthly subscription. If you'd like us to handle setup, we offer professional template conversion as a service. Pricing depends on complexity, contact us for a quote. We can also be your ongoing email development partner for new modules and template updates.
Can I get new modules added later?
Yes. As your needs evolve, your developer can add new modules, or we can build them for you as a project-based service. New layouts for product launches, seasonal campaigns, or whatever you need. Your template system grows with you.
How is this different from Stripo or Beefree?
Stripo and Beefree are email builders. They let you construct emails from scratch with full editing freedom. Modular Mail is more like a CMS: your templates define the structure, your team fills in content fields. If you need full creative freedom, use a builder. If you need consistent campaigns from established templates, use a CMS.
Why wouldn't I just use Mailchimp's email builder?
Mailchimp's builder is fine for generic templates, but limited if you want custom HTML designs. And if you do upload custom HTML, your team probably can't edit it safely. Modular Mail gives you custom designs that anyone can edit without breaking.
How does Modular Mail work with my existing ESP?
Modular Mail is completely ESP-agnostic. Build your campaigns in our editor, then export clean HTML and upload it to Mailchimp, Klaviyo, HubSpot, Salesforce Marketing Cloud, or any platform that accepts custom HTML. No integrations required.
