Escape fragile tables
Replace nested table patches and scattered inline fixes with readable layout primitives.
HTML → MJML
Convert legacy HTML into clean MJML.
Paste table-heavy email HTML, rebuild it with responsive MJML structure, and leave with code your team can actually maintain.

Iterate without fear
Change sections and content without re-learning a one-off HTML structure every campaign.
Keep a clean source
Export MJML as the maintainable source while still producing compatible email HTML.
A SAFER MIGRATION
Don’t swap the source blindly.
Conversion is a starting point. Treat inbox rendering as the final acceptance test.

Replace the production source only after required inbox clients pass.
HTML to MJML questions
Can every HTML email be converted automatically?+
Most email HTML can be translated into a cleaner MJML structure, but heavily customized or client-specific markup still needs review. Always compare the compiled output before replacing a production template.
Does conversion preserve responsive behavior?+
The workflow rebuilds layout using responsive MJML primitives. Because legacy templates vary, preview the result at desktop and mobile widths and test it in the inbox clients your audience uses.
What should I do after converting HTML to MJML?+
Review section hierarchy, replace brittle inline overrides, validate the MJML, and run a final email-client test before sending.
