Filter based on a minimum amount of emails sent and a period of time longer than 6 months?
I've recently found out "Was Sent E-mail" and "Was Delivered E-mail" are kept for only 3 months.
I was using these criteria on my Smart Lists, but now they're no longer enough... I tried to use "Member of Program", but it doesn't have any Constraints related to date or minimum of times.
What we need to do is detect users that received a minimum number of emails for an extended period of time, and if they didn't open any of these, they would be kept out of programs for at least 6 months before trying to send anything else again. Of course, the only maintainable way to do that is if the Smart list uses values based on time (X months, instead of specific date, which would require constant maintenance), and on minimum number of emails (instead of relying on specific programs or emails).
I tried looking for compatible criteria but couldn't find any that would help us achieve that... Do you have any tips or solutions?
Thanks, you all!
