No, you can't do it that way.
You can click on Design Studio>Emails to look at a list of emails, but those won't be in the marketing activities.
So you'd have to walk through each email in the system.
Yuck. Maybe I'll ask support if they can run a list.
Seems like something you should be able to see in reports....Idea time.
I have a "deliverability" report that shows me all emails sent in they system over the past six months to see if we have any issues or high number of unsubscribes. Many times I can tell that an email is operational because the unsubscribe rate is zero. You could do something similar and export the file and sort by the unsubscribe rate. It would at least give you a good starting place.
