1 template: onboarding, transactional mail, digests and announcements. MJML source, compiled HTML with inline styles, tables and VML where Outlook's Word engine needs them. All free and downloadable without signup.
A four-email onboarding series built in MJML: welcome, activation, trial ending, day-14 check-in. Built for Outlook, Gmail and Apple Mail, and it holds up in dark mode. The first email is free.

Every email starts as MJML and compiles to nested tables with conditional comments for
Outlook and VML for buttons — the structure the Word rendering engine can actually draw.
Dark mode is handled with prefers-color-scheme plus [data-ogsc]
fallbacks for Outlook.com, which rewrites colours instead of reading media queries.
The previews on each card are browser renders of the compiled HTML at 600 px, in a light and a dark inbox and at phone width. They are not captures from the mail clients themselves — where a client applies its own colour inversion we say “partial” in the support table and explain what differs.
Compiled HTML with inline styles that pastes straight into a sending service, the MJML source with a shared theme partial, and a preview page. Node is only needed if you want to rebuild the MJML — the compiled HTML works without any build step.
