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.
Judged purely as an API. What the request contract guarantees on retry, how complete the webhook event coverage is, whether suppressions are readable and writable programmatically, and how much the message log retains when something needs debugging in production.
Against high-frequency programmatic sends where a missed delivery is a product failure, React Email covers none of the capabilities this audience leans on (idempotency keys, webhook coverage, event stream, the suppressions API, batch sending, and SDK breadth), so it fits only where those needs are genuinely absent.
