I am trying to update a filtered group, which is filtered on "All Subscribers". I want to exclude subscribers with status "Unsubscribed" from All Subscribers which cant be selected in the filter, when creating the group.
The goal is to have a filtered group with subscribers that is "Active"
Any ideas of how to achieve this?
As far as i know, it can be done by creating a measure, but i am not sure how to do this.
