And even beyond seven years free data harvesting too!

Just as likely a glitch as anything, just can’t take the risk it would happen again as a main daily email personally. Glad you’re experience has been different.

I didn’t like Tutanota and am currently trying out Proton mail. I went through a stretch where I had not logged in to Tutanota (the site) for like 4-6 weeks (was checking from my phone mostly) and it deleted my account for inactivity…which being an encrypted, privacy focused website meant the recover process was super difficult.

Ultimately I decided they were a bit too fringe and not fully cooked yet and went with Proton Mail.

Honestly all these are great suggestions for today, but this area is moving so fast I almost would suggest holding off six months to a year or so for a better solution to rise to the top. Their capabilities grow daily, and you may put in the work to get this set-up and have a much more capable solution appear soon afterwards. Just a thought though, if it’s mainly for a fun experiment then try some of these out!
