​
1. Install dependencies

Get the @react-email/components package and the Postmark Node.js SDK.

​
2. Create an email using React

Start by building your email template in a .jsx or .tsx file.

email.tsx
import * as React from 'react';
import { Html, Button } from "@react-email/components";

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

  return (
    <Html lang="en">
      <Button href={url}>Click me</Button>
    </Html>
  );
}

​
3. Convert to HTML and send email

Import the email template you just built, convert into an HTML string, and use the Postmark SDK to send it.

import { render } from '@react-email/components';
import postmark from 'postmark';
import { Email } from './email';

const client = new postmark.ServerClient(process.env.POSTMARK_API_KEY);

const emailHtml = await render(<Email url="https://example.com" />);

const options = {
  From: 'you@example.com',
  To: 'user@gmail.com',
  Subject: 'hello world',
  HtmlBody: emailHtml,
};

await client.sendEmail(options);
