End-to-end encrypted emails, not massive collection of metadata to build advertising profiles, and, maybe this will sound strange, but I wanted to pay for these services because I want to show everyone that there is a paying market and you don't have to rely on advertising to be profitable in this space.

No service is capable of completely hiding IPs and still getting you the data. If you "threat model" includes hiding from Western governments, I'd recommend not using the internet.
