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.
The question here is which one a backend engineer would rather operate. That means SDK depth in the language already in use, whether a retry can safely be replayed, how much the event log tells you when a customer says the email never arrived, and whether the pricing curve stays sane as volume grows.
Against password resets, receipts, and magic links shipped from application code, React Email covers developer experience, and does not cover SDK breadth, idempotency keys, event stream, and webhook coverage. Whether that gap matters depends on how central those are to the build.
