Email quick filter
Find the email using the content filter.
Look at the sales and revenue columns.
Then look at the re-opt-in sales column.
If the re-opt-in sales count is high relative to the sales, it indicates that the majority of the sales came from existing email subscribers who re-opted in for the lead magnet/webinar, and then purchased something before re-opting in to anything else.
