I'm currently running an analysis on our DB to see if the volume of email sent or the frequency of our email promotions is negatively impacting our DB.
It seems that it's not possible to run reports on following data points and I want to check with the community if this is correct / somebody has work-arounds:
1- has unsubscribed (in general - not just from emailing) in a given time period -> it looks like we can only run this filter for last 90 days. Is that correct?
2- was part of a given segment in a given time period -> it looks like we cannot see the evolution of segments. Is that correct?
3- I can see who has unsubscribed from an email in a given time period or the min. number of emails a group has received in a given time period but I cannot see if the group has unsubscribed after email #1, #2,#3 etc. so in other words I cannot determine if the frequency of emails has led to the unsubscribe. Is that correct?
