When sending campaigns using Sendloop, you can easily include the required Google Analytics tracking code in your emails' links.
To do this, open up the specific email campaign you're interested in, and navigate to its Options page. Make sure that you've checked the box next to Enable Google Analytics.
Once you've enabled this feature, Sendloop automatically adds the required
utm_ parameters to all of the links included in your email so that you can track activities using Google Analytics.
