​
1. Install dependencies

Get the @react-email/components package and the Plunk Node.js SDK. 
npm install @plunk/node @react-email/components

​
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>
  );
}

export default Email;

​
3. Convert to HTML and send email

Import the email template you just built, convert into an HTML string, and use the Plunk SDK to send it. 
import Plunk from "@plunk/node";
import { render } from "@react-email/components";
import { Email } from "./email";

const plunk = new Plunk(process.env.PLUNK_API_KEY);

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

plunk.emails.send({
  to: "hello@useplunk.com",
  subject: "Hello world",
  body: emailHtml,
});
