I am trying to work out the engagement of our current customers. I need a snapshot of the last 6 months and track across all emails that have been sent. Is there any way of sorting which customers have opened all emails sent and which that haven’t opened any preferably by their account name?
You could try running a lead performance report
Was Sent Email in Past 180 Days IS ANY.
Opened Email IS ANY
then another list with NOT WAS OPENED.
