# Mandrill

### Connection <a href="#connect" id="connect"></a>

When you're setting up your first workflow with Mandrill, you'll need to add your API key so that Mandrill is a connected app within MESA. Mandrill is a paid Mailchimp add-on so you must have it [enabled in your Mailchimp account](https://mailchimp.com/help/add-or-remove-transactional-email/).

1\. You can locate your [API key](https://us4.admin.mailchimp.com/account/api/) by clicking your Account bubble, located at the top right on the Mailchimp Dashboard. Then, locate **Account and Billing** and click on it.
