Is there a way to show us the top people who open every email and the people who have never opened a single email without going through each contact one by one?
Thanks for reaching out to the Communinty with your great question! At this time we unfortunately do not offer cumulative open reports. This is definitely a feature request I would be happy to submit for you. However, in the meantime here is a helpful post we have in the Community on how to create an un-open report for a time frame. I apologize for any inconvenience this may cause.
