Agree. Most promotions target new users, but long-time subscribers should get something too.

Even small loyalty perks like storage boosts, renewal discounts, or feature credits would show appreciation and help retain users who have supported Proton for years.

They sort of already do, as long as they keep grandfathering subscribers into the rate they are paying now, even as rates for new subscribers rise. Over time, that may end up being a significant discount if they keep honoring that.

At least fee features such as scribe, lumo Plus, etc.

I've gotten several free Drive storage upgrades as a continued subscriber

A credits discount would be nice from them, I would purchase

They used to once upon a Time you would see little deals in your inbox little upgrades for your mail I miss that too but I understand I mean there giving away free services without stealing our data they have to make income to be able to create the technology and sustain themselves so I get it that said I do miss it.....
