How to determine if a contact has already been part of the Campaign
Hello All,
We are running a campaign every day, where every ( Author + Book Name ) is picked up with the logic of (current date - 15 days ) and passed through a campaign.
The issue with this is same ( Author + Book Name ) combination might also show up the next day too, when the campaign is run.
1. How can we ensure that (Author + Book Name ) is uniquely passed through the campaign once
2. Same Author with a different Book Name should be allowed though
Request if somebody can suggest the rule to filter this
Regards,
Dipendu
