How Does the Google Analytics Integration Work?

To use the Google Analytics integration, you do not need to do anything other than tick the check-box in the newsletter tracking options as well as in the settings (Step 5 --> Edit tracking options). 

The Google Analytics integration works via different tracking parameters which are then processed by Google Analytics. The following are attached to each of your links: the campaign name (utm_campaign = {Your campaign name}), the campaign source (utm_source = newsletter) as well as the campaign medium (utm_medium = email). 

If you want to set this as default, go to Email Settings --> Tracking --> enable Google Analytics.
