Good EU alternatives to Google's Gmail?

Hallo fellow Yuropeans! Due to the current state of affairs in the world, I am looking for decent alternatives to services I use on a day-to-day basis. So to start with, I am looking for a good alternative to Gmail. I was wondering if some of you have already used an EU alternative and what expierence you have with the service. Please don't post the link to europeanalternatives, I am aware of the existence of the site, but I am rather curious about your very own experience!
