# Mailchimp Transactional

> Provider ID: `MailchimpTransactional`

## Getting Started

Mailchimp Transactional (formerly Mandrill) is a paid add-on available to Mailchimp Standard plan users and above. It uses a separate API key from the Marketing API.

### API Key Setup

<Steps>
  <Step title="Enable Transactional Email">
    In your Mailchimp account, navigate to **Automations > Transactional Email** and purchase a Transactional block if you haven't already.
  </Step>

  <Step title="Generate a Transactional API Key">
    Open the Transactional section and navigate to **Settings > SMTP & API Info**. Click **+ New API Key**, give it a label (e.g. `Strata Integration`), and copy the generated key.
    See also the [Mailchimp Transactional Guide](https://mailchimp.com/developer/transactional/guides/quick-start/#generate-your-api-key)

    <Note>
      Transactional API keys are separate from Marketing API keys. A Marketing API key will not work with the Transactional API.
    </Note>
  </Step>

  <Step title="Configure the Integration in Strata">
    Select Mailchimp Transactional in the [Strata Integration Catalog](https://app.connectstrata.com/integrations). Enter your Transactional API key to connect.
