Comments about Tuta as a Alternative to Gmail
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 :)8
Privacy-respecting company, and has open source client6
Does not support POP/IMAP, you will not be able to use it with Thunderbird or another email client.24
Really great privacy focused service1
Replaced successfully G.Calendar G.Contacts for me. Cheap privacy first services with no compromise on the ease of use.1
