Since the "opt-ous" number on the reports page of a particular email tells the number of recipients scrubbed prior to send (due to a previous opt-out), it would be ideal to also include an "Unsubscribed" number that shows how many recipients unsubscribed via this particular email. Opt-outs and unsubscribes, as defined by Blackbaud, are two different entities. Opt-outs precede the current/particular email. Unsubscribes are a result of the current/particular email.
