Prerequisites

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

​
1. Install

Get the Nodemailer package. 
npm install nodemailer

​
2. Send email using SMTP

When configuring your SMTP integration, you’ll need to use the following credentials:
  • Host: smtp.resend.com
  • Port: 465
  • Username: resend
  • Password: YOUR_API_KEY
Then use these credentials to create a transport:
index.ts
import nodemailer from 'nodemailer';

async function main() {
  const transporter = nodemailer.createTransport({
    host: 'smtp.resend.com',
    secure: true,
    port: 465,
    auth: {
      user: 'resend',
      pass: 're_xxxxxxxxx',
    },
  });

  const info = await transporter.sendMail({
    from: 'onboarding@resend.dev',
    to: 'delivered@resend.dev',
    subject: 'Hello World',
    html: '<strong>It works!</strong>',
  });

  console.log('Message sent: %s', info.messageId);
}

main().catch(console.error);

​
