I'm working on creating an email that will be sent to a Data Extension in Salesforce marketing cloud. There are however 4 other data extensions that each contain specific subscribers. In the email, there is a banner that will be different depending on whether or not the subscriber is in one or the other data extensions. This part is working perfectly.
The next part, though, is that I'd like to be able to track in Google Analytics based on which version of the banner someone sees - or in other words in this case which DE they are in. However, all of my coworkers say that this is impossible and I'm not really sure where to begin looking. It seems, though, that this would be a simple matter of using a custom attribute? But perhaps I'm under-thinking how the UTM source etc. are being passed to GA.
