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.
An agent stack treats email as a two-way primitive. Inbound has to arrive as structured JSON a tool call can consume, sends have to be safe to retry when a model loop repeats itself, and every action needs an audit trail. A provider without inbound parsing only solves half the problem.
Against inbound parsing into tool calls and model-generated sends that must not duplicate, React Email covers none of the capabilities this audience leans on (inbound parsing, idempotency keys, webhook coverage, event stream, batch sending, SDK breadth, and multi-tenant support), so it fits only where those needs are genuinely absent.
