I've been using Mailfance (https://mailfence.com/) for around two years now and been very happy with them - the interface isn't the most beautiful thing ever, but it is simple to use and it works, and the pricing is reasonable (from free to 25,00€ a month depending on storage space needed).

I use my own domain and I do still have a separate Gmail account that I mostly use for newsletters, promotions, coupons, and other "semi-wanted spam" to keep things clean in my inbox.

Mailfence is in Belgium, so they're outside of the main Five Eyes but are still in a cooperating area and part of the Fourteen Eyes, which may matter depending on your precise personal privacy/risk levels, but for general personal privacy it's plenty for my use case.
