I want to delete cold subscribers that haven't opened emails from me for 90-days+, only. The problem with doing this in bulk currently, is that the CK system also includes subscribers that have also been on my list for less than 90-days, too. For me, it's pointless deleting these people so early on - even if they haven't currently opened any emails. Doesn't give us marketers enough time to engage and figure out if they are 'real' subscribers, or not. So, it would be helpful to be able to delete cold subs from a certain DATE RANGE. I'm sure I'm not the only person that would appreciate this.
