When I mean Unsubscribe, I mean from all communication. The action that is performed by clicking the 3 dots on Candidate profile and selecting unsubscribe from there.
We usually get a few people asking to be removed from mailing lists or requesting to not be contacted. Following the strict laws regarding this, we unsubscribe them from our database and make sure to apply the "Profile Status" filter and remove the unsubscribed ones when we search for candidates.
Currently, this process takes a couple of days to perform. Recruiterflow does have the capability to perform bulk actions. I don't know why unsubscribing is not one of them.
