I would think that a report for showing Contacts activity would be very helpful. It should show your contact, the number of campaigns sent to them and the number of opens. If I have a contact that is not opening their emails, I need to check if they are not seeing them. Or are just ignoring them.

Thank you for your feedback @EdwardS33! I too believe having a report for Contacts activity would be very beneficial to our users. I have opened up your idea for voting.
