React Email is an open-source library that lets you design transactional emails with React components, rather than with legacy email HTML, notoriously painful. Made by Resend, it provides ready-made components that handle compatibility across often-finicky email clients.

What is React Email used for?

React Email is used by developers to build maintainable, consistent email templates: you write your emails as reusable React components, with a previewable render, then send them via a service like Resend. No more nested-table HTML and client-specific hacks: the library abstracts that complexity.

React Email for whom?

React Email is aimed at technical teams sending transactional emails (confirmations, notifications) that want to treat them as modern code. It is a developer tool, not a no-code marketing platform like Brevo.

How much does React Email cost?

React Email is entirely free and open source, under the MIT license. The library and its components are free, with no paid tier. Any costs concern the chosen sending service (like Resend), not React Email itself.
