I have the requirements to send an announcement to 14,000+ students who are in the subscribers role and in a group {role-unparsed}-subscriber. I need to filter out 800 because they cancelled their admission.

What you suggested on October 18, 2018 at 7:33 am will not work for us. I’m looking for a filter on the participants array so they don’t get the message in the online system and by email.

Is there anything I can do?

Thank you.
