@tiefling I am moving my secure mail over to Posteo and I like it a lot. I have spent A LOT of time looking at providers. I went with Posteo over Proton and Tuta because it could connect with Thunderbird, has excellent and clear pricing, and good ethics. I like Tuta but it is too fiddly. Proton feels like it spends way too much time trying to upsell you. I’m finally created a Mailfence account and while it has a better UI than Mailbox.org, its pricing feels opaque.
