Offer a lower cost plan for Proton Bridge Only
It's not worth the price for the base plan, in order to take advantage of Proton Bridge, for those who aren't heavy email users.
I don't need five domains. I don't need VPN, Increased storage, or any of these increases. I'd just really like to manage email in a desktop client. Either a lower plan would need to be available or I'd need to find an alternative to Proton. There's no one I'd prefer to do business with.
