Email as a first-class output — design once, export email-ready HTML

[vnunez85]

Instatic already has a visual canvas, design tokens, and a publisher that outputs clean HTML and CSS. It feels like a natural extension to add email as an output format.

The idea: let users design an email template on the same canvas they use for pages, then export it as a downloadable HTML file with inlined, email-client-compatible markup (tables, inline styles, the whole ugly-but-necessary stack). No sending, no SMTP, no campaign management — just design and download. Users can then drop that HTML into whatever ESP they already use (Campaign Monitor, Mailchimp, etc.).

On the implementation side, two approaches come to mind:

• MJML — a markup language that compiles to responsive, email-client-safe HTML. The canvas could output MJML components instead of semantic HTML, then compile to the final inlined output on export.
• React Email — since the admin is already React, this could slot in more naturally. Components render to email-safe HTML with the same DX the rest of the editor already has.

Either way, the publisher already knows how to transform canvas output into clean markup — email would be a second compilation target rather than a ground-up feature.

Right now anyone designing emails has to jump to a completely separate tool. If the canvas could export email-safe HTML alongside its current static page output, Instatic becomes the one place for both web and email design.

Would love to hear if this is on the radar or if there's a plugin approach that could get there.
