I want an email service that doesnt expire/delete my account from inactivity. Instead of subscribing for everything i dont need, how about let us do a one time payment of lets say $5, $10. Just to make sure the account doesn't get disabled or even a grace period extension to something like 5 years of inactivity, permanently for that account.

Free accounts only store 1gb of data anyway, so the storage shouldnt take up a lot for a permanent account. Plus $5-$10 for 1gb sounds like it would pay for itself and be worth it for proton?
