Email filter Question
I have a question regarding filters within the Campaign feature. Here is the scenario.
We have an email that we want to send as part of a campaign, we will call it "Email A". Now, we only want to have "Email A" sent to our customers if:
A) They have not received "Email B" in the past 45 days.
B) They have not received Email C this year.
How could this be setup as a filter within this campaign? Thanks in advance for any assistance.
