Structured + MJML in one editor
Drag-or-paste sections (hero, text, image, button, divider, footer) or jump to raw MJML. The structured schema persists alongside the rendered MJML so both views stay in sync.
Templates
MJML templates with a live preview that's actually live
Visual section editor, MJML source view, brand kit, version history, content checks — and a preview that renders the same MJML your recipients will receive.
Build templates with the structured section editor or paste raw MJML — whichever fits the moment. Mailbase applies your brand kit colors and logo, runs spam-content + link checks, and keeps a versioned history so you can restore an earlier draft.
Brand kit, applied automatically
Logo, primary + accent colors, sender signature — set once per workspace, applied to every template that uses the matching variables.
Content checks + link checker
Spam triggers, missing unsubscribe link, broken external URLs — all caught before send. Optimizer suggests readability and CTA clarity fixes you can apply with one click.
