Users Unsubscribe From App Emails - What Happens?

Adding visibility into unsubscribes and providing a developer-managed way to handle them would be highly beneficial. Currently, there isn't a built-in way for me as the developer to: See which of my users have unsubscribed from emails - Receive notifications when someone unsubscribes - Manage or reset unsubscribe statuses myself from your app dashboard If a user accidentally unsubscribes.
