# Mailchimp Transactional Emails

The Mailchimp destination sends emails using **Mandrill** (Mailchimp Transactional API). All recipient and content information comes from your incoming data—no Mailchimp list or audience is used. You can send one email per row or one email per group when using Group By.

<Note>
  You need a **Mandrill API key** from Mailchimp: Account & Billing → Extras → Mandrill. This is separate from the Marketing API key. Verify your sending domain in Mandrill so emails can be delivered.
</Note>

### Setup

<Steps>
  <Step title="Credentials">
    Create a Mailchimp destination and complete the **Credentials** step:

    * **Mandrill API key** (required): Your Mandrill API key from Mailchimp.
    * **From email**: Sender address for outgoing emails. Must be a verified domain in Mandrill. Defaults to [noreply@less.tech](mailto:noreply@less.tech) if empty.
    * **From name**: Display name for the sender.
  </Step>
