I was asked the other day if the new Google Analytics 4 needs to be set up for traffic which needs to be manually ‘tagged’, such as emails.

Anyone having used the campaign utm tag can add a secondary dimension by clicking the “+” and selecting “Session Campaign” under “Traffic Source” as the secondary dimension. Otherwise, selecting “Session Source” and “Session Medium” as separate dimensions can look neat, like this:
