What React Email is

React Email is a library of email components for JavaScript and TypeScript developers building messages with React. Its ready-to-use pieces include headers, footers, buttons, images, and layouts; styling can use Tailwind or inline CSS. The editor examples show rich text, columns, buttons, images, theming, custom extensions, and export to email-ready HTML. The project says it can be introduced incrementally into most codebases.

A CLI development server watches template files and rebuilds them when they change. A render utility converts React components into an HTML string for use with an email service provider. Documented sending integrations include Resend, Nodemailer, Mailgun, SendGrid, Postmark, AWS SES, Azure Communication Email, MailerSend, Scaleway, Plunk, Lettermint, eusend, and Brevo. The project also describes a link linter, an email-client compatibility checker, and a spam score tool. Its components are said to be tested with Gmail, Apple Mail, Outlook, Yahoo! Mail, HEY, and Superhuman. React Email is open source under the MIT license and is brought to you by Resend; the project began as an open-source project in 2022. The CLI's static preview files are not hosted with sent emails, so production assets need another source URL.

Who it suits

React Email suits JavaScript and TypeScript developers who want to build email layouts from React components and add the library to an existing codebase incrementally. It also fits teams that need HTML output for a documented sending integration and want tools for checking links, compatibility, or spam scores.

What it does well

Reusable components cover headers, footers, buttons, images, and layouts.
Supports Tailwind and inline CSS styling.
CLI server watches files and rebuilds templates.
Render utility converts components to email-ready HTML.
Documented integrations include Resend, Mailgun, SendGrid, and Brevo.
MIT-licensed and open source.

What to know first

CLI preview static files are not hosted for sent emails.
Components must be rendered to an HTML string for provider use.

Limits

The project is free and open source. Files in the CLI preview's static directory are served for preview but are not hosted for sent emails; production assets need another source URL.

Getting started

Open https://react.email/.
Add React Email incrementally to a JavaScript or TypeScript project.
Build a message with the copyable components and Tailwind or inline CSS.
Use the CLI development server to preview templates as files change.
Render the components to an HTML string for an email service provider.
Configure a documented sending integration.

Verdict

Choose React Email if you build emails in JavaScript or TypeScript and want reusable React components, a local rebuild workflow, and HTML output for a sending provider. Look elsewhere if you need preview-directory assets to be hosted automatically with sent emails; production assets require another source URL.
