Hello @DebraG71 ,
The easiest method for a contact to resubscribe to you, would be through one of your sign up forms.
If they’re unable to get signed back up through a sign up form, you can request our Review team do a manual override of the unsubscription. You’ll need to get an email directly from the contact explicitly stating they want to be resubscribed. Then you’ll need to call into the Review team, and follow their processes from there.
Since there are a number of legal and Compliance-related elements to unsubscribing and resubscribing, we have to make sure one of these two processes is followed.
