1. Install dependencies

Get the @react-email/render package and the MailerSend Node.js SDK.

npm install @react-email/render mailersend

2. Create an email using React

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

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>

3. Convert to HTML and send email

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

import { render } from '@react-email/render';
import { MailerSend, EmailParams, Sender, Recipient } from "mailersend";
import { Email } from './email';

const mailerSend = new MailerSend({
  apiKey: process.env.MAILERSEND_API_KEY || '',

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

const sentFrom = new Sender("you@yourdomain.com", "Your name");
const recipients = [
  new Recipient("your@client.com", "Your Client")

const emailParams = new EmailParams()
  .setSubject("This is a Subject")
