Everytime i submit a new support case, i don't need a confirmation email. I can easily see all of my cases in the app itself. Also, when a case is closed, i get 2 emails. one telling me the case is closed (unsubscribe, please!), and another for a feedback.
I get you want feedback, but maybe some other way... i just automatically delete all these emails.
Can i just unsubscribe from them instead?
