How to set up the Mailchimp integration
First, navigate to the campaign where you'd like to connect the Mailchimp integration, then click "Integrations" from the menu on the left side of the screen.
Click on Mailchimp in the list of available integrations.
Then click Connect Account.
In the window that appears, enter the username and password for the Mailchimp account that contains the campaigns that you would like to connect. Then, click "Save".
If you have multiple client Mailchimp accounts connected to your root Mailchimp account, you'll then be prompted to select the account to connect. Once you do so, the integration will then be complete, and your client's Mailchimp metrics will then be imported and displayed within the dashboard.
