Thrilled that received at reporting is possible now. When I pull the data though, I'm not sure I understand what I'm seeing so I'd like to pose it as a hypothesis, and there doesn't appear to be much documentation on the attribute itself.
The ticket email data only exists for tickets that have been updated since go-live of the attribute; older, closed tickets will not have data in that attribute until they are touched. Updates could include an running a one time touch automation, and then the ticket email data would update.
Is that correct, or is there some other reason that 8 of my top 10 support emails don't have tickets received in October (the report below is filtering out tickets where ticket email is NULL and selecting for only created in the last 2 months)? Am I wrong about how to reverse-populate the ticket email data with an automation?

I'll have to create a ticket for this concern to investigate further. Please wait for my update via email and let's start from there.
