React Email

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.

A SaaS product sends on behalf of its customers, so the deciding factors are tenant isolation, whether suppressions can be scoped rather than global, and whether support can answer why one specific account did not receive one specific email. Lifecycle automation and transactional sending usually need to coexist.

Against trial expiry notices, dunning, onboarding sequences, and per-tenant transactional mail, React Email covers none of the capabilities this audience leans on (multi-tenant support, event stream, the suppressions API, scheduling, and webhook coverage), so it fits only where those needs are genuinely absent.
