Lovely way to give the snoopers the middle finger.

Fastmail for 10 years or more. It is completely reliable, never had a single problem. I think I pay $20.00/year for some storage and a very safe site without problems.

I forgot, they sold out to Opera at one time and I was looking around for another mail program. By the time I actually got around to choosing a couple to check out Opera sold it back to the original owners who have done a huge amount of work to make it even better than it was before.

I think Proton is wonderful. I don't have it but I looked at it recently when my husband wanted a secure mail site but he eventually went with Fastmail as well.

not free, around $60 / year. you can have extra alias emails, temporary or permanent, great feature for a number of reasons.
