Prerequisites

To get the most out of this guide, you’ll need to:

​
1. Install

Get the Resend Node.js SDK. 
npm install resend

​
2. Send email using HTML

Create a Server Route under server/api/send.ts. The easiest way to send an email is by using the html parameter. 
import { Resend } from 'resend';

const resend = new Resend(process.env.RESEND_API_KEY);

export default defineEventHandler(async () => {
  const response = await resend.emails.send({
    from: 'Acme <onboarding@resend.dev>',
    to: ['delivered@resend.dev'],
    subject: 'Hello world',
    html: '<strong>It works!</strong>',
  });

  if (response.error) {
    throw createError({
      statusCode: 500,
      message: 'Error sending email',
    });
  }

  return response;
});
