Who HASN'T opened an email in the last "X" weeks, months, years?
I would like to be able to move my un-responsive (or non-active) clients to a separate list, or at least segment them in some way.
Is there a way to find out who hasn't opened an email (from a broadcast or AR) in the last 12 months, or last 2 years?
Is there a custom filter that I can use to find out, or any other way to know this? If not, could you consider adding this function?
