      onuni Tutanota is the best choice, because it is simple and run by an awesome team. Even the Premium prices are very affordable.

      Does not support POP/IMAP, you will not be able to use it with Thunderbird or another email client.

      justinterested Tutanota is a great email provider with very good encryption (it uses end-to-end encryption like Signal – i.e. they cannot read your emails/gife them to the government, Gmail can!) and they don't sell any data. It is also very easy to use, it has a very nice app, a desktop client and a web client. There is really no reason why you wouldn't want to use it :)

      This is a very good free client. It gives you lots of functionality even at no cost.
