A Better Email Builder for Salesforce Marketing Cloud

Supercharge your workflow with reusable modules, live previews and effortless exports to Email Studio.

The Problem

Why Real-World SFMC Users Struggle

Even with SFMC's powerful marketing capabilities, creating emails can still be challenging. Here are some common pain points and why a modular approach can help:

Steep Learning Curve & Poor UX

SFMC's email builder can feel unintuitive and sluggish, making it hard for marketers to assemble and preview campaigns efficiently. When working with complex designs, teams often have to rebuild layouts manually because the builder still relies on table-based structures, costing hours of extra work.

Rigid Design & Component Limits

Email Studio imposes a 250-component limit and a 10,000 character cap per block, which forces sophisticated designs to be broken across multiple sections. Pardot users have even less flexibility, as there's no native drag-and-drop editor or API for importing templates.

Limited Styling Flexibility

Customising the look and feel of your emails is difficult: you can't select your own web-safe fonts, bold text inside buttons or prevent Salesforce's auto-generated classes from overriding your styles. Maintaining brand consistency often requires hand-coding.

Code Bloat & Accessibility Issues

The builder generates verbose HTML with nested <span> tags, no CSS reset and missing accessibility attributes such as a <lang> tag. This bloat makes templates harder to maintain and can negatively affect deliverability and compliance.

Mobile & Rendering Limitations

Emails built in SFMC don't always render consistently on mobile devices or across different clients. Reviews note that column spacing and layout elements can break unexpectedly, requiring additional testing and fixes.

Slow, Clunky Workflows

Setting up triggered campaigns and segmentation in SFMC can be cumbersome. Without a modular approach, even small content changes often require developer assistance, so campaign updates take days rather than minutes.

The Solution

How Modular Mail Solves SFMC's Email Builder Challenges

Even if you rely on SFMC for automation and CRM, you can enhance your workflow with a flexible, modern builder. Here's how Modular Mail addresses common challenges while keeping your Salesforce workflows intact.

Intuitive, fast-moving editor

Say goodbye to inefficient interfaces. Modular Mail's visual drag-and-drop builder is designed for non-technical marketers, so you can assemble and preview campaigns quickly and confidently. There's no code to learn and no table-based layouts to wrestle with.

Flexible design with no limits

Instead of working around a 250-component cap or splitting designs into tiny fragments, you build with reusable modules that can be mixed and matched freely. Each module is coded to respect SFMC's constraints, giving you the design flexibility you need without breaking the platform.

Full control over styling

Choose your own web-safe fonts, bold your button copy and set global tokens for colours, spacing and typography. Because the design system lives in Modular Mail, you control every detail of your brand without worrying that SFMC will overwrite your settings.

Clean, accessible code by default

Behind the scenes, Modular Mail outputs streamlined HTML with a proper CSS reset, semantic markup and all necessary accessibility attributes. That means lighter emails, better deliverability and peace of mind around compliance.

Reliable mobile & client rendering

Each module is tested across major email clients and mobile devices, so your layouts stay consistent wherever they're opened. Plus, you can preview responsive behaviour before exporting, reducing last-minute fixes.

Faster production without developer bottlenecks

With a central library of approved blocks and one-click exports back into SFMC, routine updates no longer require developer intervention. Marketing teams can build and revise campaigns at their own pace, shortening production cycles and freeing up technical resources for more strategic work.

How It Works

From SFMC Template to Campaign in 3 Simple Steps

Set up once, then accelerate every campaign. Here's how Modular Mail enhances your SFMC workflow.

Upload Your Design System

A developer uploads your master HTML template (or Figma design) and defines reusable modules using simple mm-editable tags. This one-time setup takes 1-2 hours. Our expert team can help convert existing SFMC templates.

Build Campaigns Visually

Build campaigns visually with approved modules; your design remains intact while content is flexible

Export Clean HTML to SFMC

One-click export generates production-ready HTML that respects SFMC's formatting and component constraints. Upload to Email Studio or any ESP—your emails will render consistently across all major email clients and devices.

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?

Converting your first template typically takes a couple of hours. Once set up, your team can reuse modules and build campaigns quickly using familiar designs.

? 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.
