Send React Emails Code Example in 2024

Send React web app emails with HTML, CSS, and JSX templates, examples, and SMTP production-ready integration.

Install and Requirements

You will need to install @react-email/render og nodemailer npm dependencies:

npm install @react-email/render nodemailer

Source Code and Example

Create your email template with a .jsx or a .js file:

// email.jsx
import * as React from 'react';
import { Html } from '@react-email/html';
import { Button } from '@react-email/button';

export function Email(props) { const { url } = props;

return ( <Html lang="en"> <Button href={url}>Visit our website</Button> </Html> ); }

In this example, we use the Nodemailer library and its official sponsor Forward Email to send and preview outbound mail.

You will need to Generate Password to send outbound mail – please follow our Send Email with Custom Domain SMTP Guide.

// app.js
import { render } from '@react-email/render';
import nodemailer from 'nodemailer';
import { Email } from './email';

const transporter = nodemailer.createTransport({ host: '', port: 465, secure: true, auth: { // TODO: replace user and pass values from: // <> user: '', pass: '****************************' }, });

const html = render(Email({ url: "" }));

const options = { from: '', to: '', subject: 'hello world', html };


Run the app to send the email:

node app

Now you can go to My Account → Emails to see your real-time email delivery status, email deliverability logs, and HTML/plaintext/attachment previews.

P.S. 🎉 You can also preview emails in browsers and the iOS Simulator og create email templates with Node.js.
