What is Modular Mail?
Modular Mail is a content management system for email. Your developer turns your HTML email templates into a library of modules, each with a simple form. Your marketing team builds campaigns by adding modules and filling in the forms, with a live preview beside them. When an email is ready, they export the HTML and send it from the email platform you already use.
The design lives in the template, so nobody can break it. The content lives in the forms, so nobody has to wait for a developer to change it.
How it works
Section titled “How it works”- A developer sets up a template once. They paste in the email’s HTML, split into a header, a footer and modules such as a hero, a product grid or a text block. They mark the parts that should change with a
data-mmattribute and give each one a field: text, an image, a link, a colour, a layout choice and so on. - They publish it. Publishing creates a version your team can build campaigns from.
- A marketer builds a campaign. They pick modules from the template’s library, drag them into order and fill in each module’s fields. The preview updates as they type, at desktop and mobile widths.
- The team reviews it. Reviewers comment on any part of the email and approve it. Statuses show where every campaign stands.
- The marketer sends a test and exports. Modular Mail compiles the email into one HTML file. Paste it into Klaviyo, Braze, Salesforce Marketing Cloud, Mailchimp or any platform that accepts HTML.
Modular Mail never rewrites the developer’s HTML. When it builds an email, it copies the template exactly as written and only swaps in the values from the form. Spacing, fonts, Outlook fixes and dark mode rules all reach the inbox unchanged.
Who it’s for
Section titled “Who it’s for”In-house email and CRM teams whose emails are built from custom HTML that their ESP’s visual editor can’t open. Marketers stop waiting in a developer’s queue for every banner swap.
Email developers who want to hand over a template without handing over the code. You decide what can change, how long each headline can be and which colours are allowed.
Agencies who build templates for clients. Clients build their own campaigns from your modules, and reviewers on the client side comment and approve for free.
E-commerce and content teams who fill emails from a Shopify store or a WordPress site. Pick a product or a post and its title, price, image and link fill the module.
What Modular Mail isn’t
Section titled “What Modular Mail isn’t”It isn’t an ESP. Modular Mail doesn’t hold your lists or send your campaigns. It sends test emails only. Your ESP still sends the real thing, so your audiences, flows and reporting stay where they are.
It isn’t a drag-and-drop email designer. Tools such as Stripo and Beefree are for designing each email from scratch. Modular Mail is for teams whose design already lives in a template and who want to keep it that way.
