How to setup the Constant Contact integration
First, navigate to the home dashboard for the campaign where you'd like to connect the Constant Contact integration. Then, choose "Email --> Constant Contact" from the dark navigation bar on the left-hand side of your screen.
Next, click the link in the middle of the screen that says "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.
