I set an export of unsubscribers data, i.e. event date, first and last name, email, ...
In this export I would like to add a column that identifies the delivery in which the profile clicked on "unsubscribe" and then unsubscribed via landing page.
I tried a lot of different export but I'm not able to find a way to add this information. For example I added tracking logs to additional data in the query but this column is filled with the delivery of the first unsubscribe. It's not so common, but can happen that a profile unsubscribed, then subscribed and unsubscribed again.
Has anyone an idea to accomplish this purpouse?
I'm quite surprised that there is not an easy way to collect this information.
