Resend is an email API for developers, with a clean SDK, great deliverability defaults, and React Email for writing templates as components. It targets the transactional email that apps send — sign-ups, receipts, notifications — and also supports broadcasts.

Highlights

React Email for component-based templates
Strong deliverability defaults

Aimed at developers, not marketers

Transactional email

Resend is the developer's choice for sending email from an app: a clean API, React Email templates, and sensible deliverability defaults. It is not a marketer's campaign tool — for creator newsletters use Kit or beehiiv. When the job is reliable, code-driven transactional email, Resend is the modern default.
