Hi, I have created a Dynamic List with 2 criteria to be used as a supression list:

- Prospect email opens Prospect has not opened an email in the past 60 day(s)

AND

- Prospect list: Prospect is on list XXX

However the output of that dynamic list includes too many prospects, some of them I've checked manually to confirm they did opened emails in the past 60 days. (and are part of that list)

Do you know why this could be happening, any workaround?

Regards,

David.
