Is there is a way to make the default unsubscribe page shows two options.
When a recipient clicks on the unsubscribe link, the page will show two options. 1. Unsubscribe from this service. 2. Unsubscribe from all the services (black list).
You can make it.
Ex: If you are going to create unsubscription page using webapp there you can create two checkbox.
Please let me know how you are unsubscribing.
