How to set up 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.
Next, either search Constant Contact in the upper right search box, or click the Email category, then click Constant Contact.
Then click Connect New 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.
