Hi Phuong,OK, so it makes sense. In my first post, I advised to check
the exclusion tab of the delivery, it should have shown to you the
blacklist excluded count.In Adobe Campaign Classic, it is possible to
unselect the blacklist exclude rule in a specific delivery exclusion tab
of the target delivery. But I don't know whether it is possible as a
workaround in ACS. And probably it is a bit risky for GDPR legal, you
must check and recheck again RegardsJS
