That’s a really cool design. I appreciate the font and gradient stuff, nice job. You’re also including great recommendations.
If I would give feedback (as you requested) to something small it could be that self-hosted email option is not really deserving the ‘best privacy’ label in my personal opinion. I would phrase it as the ‘most verifiabile privacy’ but this could be a semantics thing as well. I feel like that’s the only benefit for self-hosting email like that: full verifiability
(And some threat modeling bits might also be nice to include here and there, but idk if it would fit).
Overall great stuff!
