Updating a service based on a specific flag in Profile details
E.g., there is a service named ABC opt-in, and on the Profile details page, there is a flag to mark/unmark the services available.
Is it possible to subscribe/unsubscribe from the service by setting the flag to true/false in the service checkbox on the Profile details page?
Checking the service option on the Profile details page will not help update the subscription history.
This will only be possible if the receiver has clicked on the unsubscription/subscription link in the email received.
