# Resend

The Resend destination sends transactional emails using the **Resend API**. All recipient and content information comes from your incoming data. You can send one email per row or one email per group when using Group By.

<Note>
  You need a **Resend API key** from [resend.com/api-keys](https://resend.com/api-keys). Make sure to verify your sending domain in Resend so emails can be delivered.
</Note>

### Setup
