React Email
Build emails with React components.
React Email provides a component library and dev server for authoring emails as React components. Built and maintained by the Resend team. The de facto standard for code-driven email in React stacks.
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, React Email 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.
