I'm trying to pull a contact list that includes last email opened. I looked at creating a custom field but I cannot figure out how to have it mapped to the last item in the campaign activity log. I just need a field with the email name, that's it. (We have multiple emails running at once so it would be a bit tedious to export a smart list for every email, so I'm looking for an alternative.
Or how can I update Last interesting moment to include ALL marketing emails sent?
