Notifications Admin has a Suppression List for phone numbers and emails. Typically, users will be added to this list when they have reported message(s) as Spam, but this can happen for other reasons such as an error message being returned or invalid recipient information.
When users are added to the email suppression list, they are now removed from any subscription lists they may have previously subscribed to for that Organization. We also indicate that the phone numbers have “unsubscribed” on our callback webhook, so these users should be automatically unsubscribed from Web Central subscription lists.
Administrative users now have the ability to see users that have been added to the Notifications Admin service suppression list from the Subscribers screen.
