How to setup the Constant Contact integration
First, navigate to the campaign where you'd like to connect the Constant Contact integration, then click "Integrations" from the menu on the left side of the screen.
Click on Constact Contact in the list of available integrations.
Then click Connect Account.
In the window that appears, enter the username and password for the Constant Contact account that contains the campaigns that you would like to connect. Then, click "Save".
The integration will then be complete, and your client's Constant Contact metrics will then be imported and displayed within the dashboard.
