Deleting Emails
You may search for an email address, domain or MD5 hash in your Opt-Out Lists, and either remove those records from your suppression files, or see the history of if/how they were added to your list eg. John opted out and now wishes to re-subscribe. You can search for his email and delete it from your Opt-Out List so he can be added back to your list. In both options below, any Global Opt-Out list that might be present in the account will also be searched.
