EasyMJML Builder

Features

Alternative builder to GrapeJS

Gives Mautic users a completely different editing experience, ideal for teams that want a more structured, MJML-based workflow.

Zero-migration setup

Opens existing Mautic email templates as-is, with no changes or conversion needed to start using it.

Layer tree

Displays the full email block hierarchy in real time, making it easy to navigate and reorganize nested sections without clicking around the canvas.

Cleaner, more stable output

Unlike GrapeJS, it doesn't inject unnecessary CSS classes into the email's HTML, producing leaner, more predictable code that is easier to maintain.

Full block editability

Every element - text, image, button, spacer, divider - is fully editable directly in the canvas, with complete control over content and styling.

Mature open source foundation

Built on Easy Email, a well-adopted MIT-licensed project with strong community support and proven stability.
