Send emails with Deno Deploy

Learn how to send your first email using Deno Deploy.

Prerequisites

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

• Create an API key
• Verify your domain

1. Create a Deno Deploy project

Go to dash.deno.com/projects and create a new playground project.

2. Edit the handler function

Paste the following code into the browser editor:

main.ts

import { Resend } from 'npm:resend';

const resend = new Resend('re_123456789');

Deno.serve(async () => {
  try {
    const response = await resend.emails.send({
      from: 'Acme <[e-mail]>',
      to: ['[e-mail]'],
      subject: 'Hello World',
      html: '<strong>It works!</strong>',
    });

    return new Response(JSON.stringify(response), {
      status: response.error ? 500 : 200,
      headers: {
        'Content-Type': 'application/json',
      },
    });
  } catch (error) {
    console.error(error);
    return new Response(null, {
      status: 500,
    });
  }
});
