Email editor

The email template editor is a visual, block-based editor built on MJML. You compose your message from blocks and let the editor handle producing email that renders reliably across clients.

How it compiles

When you save, the editor compiles the MJML source into responsive HTML. It stores both the MJML source and the block tree, so you can reopen and keep editing visually later while EngageApp always sends the compiled HTML.

What you can add

• Merge fields — insert {{ variable }} placeholders (e.g. {{ first_name }}) that resolve per contact at send time.
• Images — pull from your Assets library so media is CDN-backed and reusable.
• Buttons and links — add clear calls to action.

Preview before saving

Use the preview to check how blocks render and how merge fields fill in before you save. Saving compiles and stores the template, ready to reference from a campaign.

Where it is used

This editor produces the content sent by the Email channel. Author here, then reference the template from a campaign's send message step.
