MJML
Markup language for responsive email.
MJML is a markup language that compiles to table-based HTML that renders consistently in Outlook and Gmail. Vendor-neutral, broad framework integrations including mjml-react.
At an early stage the deciding factors are what the free tier actually covers, what the first paid invoice looks like, and how much of a founding engineer's week the setup costs. Feature depth that only matters at a million sends a month is noise until it is not.
Against a waitlist, a launch announcement, onboarding email, and the first transactional sends, MJML covers developer experience, and does not cover scheduling, SDK breadth, and webhook coverage. Whether that gap matters depends on how central those are to the build.
