Agree. I am using the German email provider mailbox.org They even report how often the government forces them to release info with a search warrant. However, I have yet to find an email provider that mimics Gmail's tagging system (=> you can give n many tags to a single email and that email is only kept once on the server). I often think that Google's "Don't do evil" motto is stretched way too often these days.
> However, I have yet to find an email provider that mimics Gmail's tagging system IMAP does support keywords, which are basically tags. Probably some good IMAP-Client supports this? There is also JMAP as a modern alternative to IMAP in development. Fastmail released a beta-interface for this, which also includes tag-support AFAIK. And finally, Outlook surprisingly seems to support tagging, but they call it categorie…
I have used Thunderbird and Evolution mainly. They cannot really do that afaik.
> Probably some good IMAP-Client supports this? The Gmail clients do that (at least the last version's I remember 3 years ago). Haven't seen any other FOSS that does so too. That is what made going away from Gmail kind of "hard".
Currently I'm using K9 on Android and the web client by mailbox.org based on OX AppSuite. Both are ok, but usability could be better.
