# 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)

<Steps>
  <Step title="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>
  </Step>

  <Step title="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);
    ```
  </Step>
</Steps>
