Install and Requirements

You will need to install @react-email/render and 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: 'smtp.forwardemail.net',
  port: 465,
  secure: true,
  auth: {
    // TODO: replace `user` and `pass` values from:
    // <https://forwardemail.net/guides/send-email-with-custom-domain-smtp>
    user: 'you@example.com',
    pass: '****************************'
  },
});

const html = render(Email({ url: "https://example.com" }));

const options = {
  from: 'you@example.com',
  to: 'user@gmail.com',
  subject: 'hello world',
  html
};

transporter.sendMail(options);

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 and create email templates with Node.js.
