Faster campaign production
Build campaigns in hours instead of days. Reusable modules and a visual CMS interface let marketers work independently.
Email Template CMS for Salesforce Marketing Cloud
Protect your email design system while giving marketers the freedom to update content. Build campaigns with reusable modules, preview instantly, and export to SFMC.
If SFMC Content Builder keeps breaking your email templates, you are not alone. Marketing teams report spending hours troubleshooting template issues, needing developers for every change, and dealing with rigid design limits. Modular Mail is an email template CMS that works alongside Salesforce Marketing Cloud. It gives you structure protection and content flexibility without the developer bottleneck.
The Problem
Common SFMC Content Builder Challenges
SFMC is powerful for automation and CRM, but Content Builder and Email Studio have limitations that slow down email production. Here is what teams run into:
Content Builder Learning Curve
Content Builder can feel unintuitive for marketers who just want to update copy or swap images. The interface is complex, previews are slow, and teams often need training just to make basic changes. An email CMS with simple content fields solves this.
Template Breaking and Component Limits
Content Builder has a 250-component limit and templates can break when updated. Blocks get duplicated, layouts shift unexpectedly, and Journey Builder edits require creating new versions. A CMS approach keeps your template structure protected.
Brand Consistency Problems
Content Builder auto-generates CSS classes that override your styles. You cannot use custom web fonts, and button styling is limited. Maintaining a consistent email design system requires hand-coding or external tools.
Developer Dependency
Most Content Builder changes require developer help. Marketing teams cannot update templates without risking broken layouts. An email CMS separates content from code so marketers edit fields while developers control the structure.
Rendering Issues Across Clients
Emails built in Content Builder do not always render consistently in Outlook, Gmail, or mobile clients. Column spacing breaks, images scale incorrectly, and teams spend hours testing and fixing issues that a pre-tested module system would prevent.
Slow Production Cycles
Campaign updates take days instead of hours because every change goes through developers. Journey Builder is rigid for email edits. With an email CMS, marketers make content updates independently while the design system stays intact.
The Solution
How an Email CMS Solves Content Builder Limitations
Modular Mail is a CMS layer that sits alongside SFMC. You keep using Salesforce for automation and sending while gaining a proper email design system with protected templates and editable content fields.
Content fields, not code
Marketers edit text, images, and links through simple content fields. No code knowledge required. The CMS interface shows exactly what can be edited, so teams build campaigns confidently without touching HTML.
Protected template structure
Your email design system stays locked. Developers define the module structure once, and that structure cannot be broken by content editors. No more duplicated blocks or shifting layouts when templates are updated.
Your design system, your rules
Define global tokens for colors, fonts, spacing, and typography. Your brand guidelines are built into the system, so every email stays on brand. No more SFMC overwriting your styles or limiting your font choices.
Clean HTML that works everywhere
Export production-ready HTML with proper CSS resets, semantic markup, and accessibility attributes. The code is optimized for email clients, so you get better deliverability and consistent rendering without manual cleanup.
Pre-tested modules
Every module is tested across Outlook, Gmail, Apple Mail, and mobile clients before you use it. Preview responsive behavior in the editor, then export knowing your layouts will render correctly everywhere.
Marketing independence
With a central library of approved modules and one-click SFMC export, marketing teams update campaigns without developer help. Production cycles shrink from days to hours, and developers focus on strategic work instead of routine edits.

FAQ
Frequently Asked Questions
Can I continue using Salesforce Marketing Cloud with Modular Mail?
Absolutely! Modular Mail is ESP-agnostic. You build your emails in Modular Mail and export clean HTML that you can upload directly into SFMC or any other ESP. You don't need to replace your existing tools, just supercharge your email production.
How does Modular Mail handle SFMC's 250 component limit?
SFMC's 250-component limit applies to its built-in drag-and-drop editor. When you use Modular Mail, you build your email outside of SFMC and export a complete HTML file. That means you're not restricted by the number of content blocks inside Email Studio, and you can design as many modules as you need while still respecting Salesforce's formatting guidelines.
How long does it take to migrate from SFMC's email builder?
It varies by template complexity—from a few hours for simpler designs to a day or two for templates that need restructuring. We'll help you scope this during onboarding so there are no surprises.
How do I ensure my emails render consistently?
Modular Mail gives you control over your HTML rather than generating it for you. Your developer defines the code for each module and can follow modern best practices and accessibility guidelines. Once built, those modules can be reused and will render consistently across major email clients.
Can non-technical users really build emails without breaking them?
Yes. Only the text, images and links are editable. Layout and styles are locked by the developer, so marketers can confidently update content without touching code.
What if I need help migrating my templates?
Our team offers onboarding assistance and can convert your existing designs, including Figma files or SFMC templates, into modular templates. We're available to support you throughout the process.
Do I lose any SFMC features like AMPscript or personalization?
Not at all. Modular Mail exports HTML that works with all SFMC features. You can add AMPscript, personalization strings, and dynamic content after importing the HTML into SFMC. Modular Mail handles the design and structure; SFMC handles the sending and personalization.
How does pricing compare to SFMC?
We offer transparent, scalable pricing with a 14-day free trial. Plans are designed to be accessible for teams of all sizes.
Can I use this for Pardot too?
Yes. You can build and export modular templates for Pardot just as you would for SFMC, giving your team a consistent workflow across platforms.
