Many of us are migrating from US services to EU based ones, so I would like to give a warning, services like #mailbox and #posteo are great, very good value for money, based in Germany, private and secure, however there is a clause that can make you pause, if you fail to pay and don't do it within 30 days your account will be deleted.

From mailbox T&Cs | Cancellation policy

"Your account with mailbox.org is a prepaid account. If you do not deposit credit, or if the deposited credit runs out, then your account will be deleted after 30 days (Section 6 of our General Terms and Conditions). After another 30 days we delete all the Data that we stored for you (Section 5 of our General Terms and Conditions)."

It may not seem terrible, but if it is your main or only email account you may lose everything if you are unable to top up your account for some reason (like going on vacation to the US and being detained for no reason)

This is probably not an issue for many, but I think that it is something worth mentioning because some may not be aware while signing (although this bubble is likely to read the TOS in full) , services like #tuta and #protonmail at least have a free backup plan.
