# Send emails using Nodemailer with SMTP

> Learn how to send your first email using Nodemailer with SMTP.

## Prerequisites

Before you start, you'll need:

* A Resend [API key](/create-an-api-key)
* A [verified domain](/add-a-domain)

## 1. Install

Get the [Nodemailer](https://www.npmjs.com/package/nodemailer) package.

<CodeGroup>
  ```bash npm theme={"theme":{"light":"github-light","dark":"vesper"}}
  npm install nodemailer
  ```

  ```bash yarn theme={"theme":{"light":"github-light","dark":"vesper"}}
  yarn add nodemailer
  ```

  ```bash pnpm theme={"theme":{"light":"github-light","dark":"vesper"}}
  pnpm add nodemailer
  ```

  ```bash bun theme={"theme":{"light":"github-light","dark":"vesper"}}
  bun add nodemailer
  ```
</CodeGroup>

## 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:

```js index.ts theme={"theme":{"light":"github-light","dark":"vesper"}}
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);
```
