Earlier quoted context omitted.
Also german ones mailbox.org, posteo, tutanota and norwegian runbox. Mailbox has been around since early 90s ive been happy user for a longtime. You make good point that Swiss (German also) laws should protect your privacy more than US laws. That includes fastmail and icloud.
I would advise everyone to stay away from services that also provide and allow use of an email address on their (provider) domains i.e. user-name@service-provider.tld (e.g. name@mailbox.org) but don't have any free tier (even the bare minimum). So the moment you stop paying you are cut off and if you had been using email on their domain you might be less inclined to migrate away even if better competitors are around…
I was a FastMail user until Gmail’s launch and regret that I abandoned my free FastMail account and it was deleted. Not sure if I ignored email warnings and that was years before Twilio so there were no SMS reminders and iOS didn’t exist so there were no push notifications to try to give me a last chance! I wish I hadn’t lost years of personal email history, especially since there were probably photos there that I didn’t have anywhere else. Back in those days, data was expensive enough that they probably wouldn’t think of automatically archiving your account into a zip file in case you came asking for it later (when I asked, it was long gone). Now I wouldn’t hesitate to pay if I could resuscitate that account. Can’t really blame FastMail and now I use them for a business and love their service but it was a good lesson for me.
