I like @Tutanota as email provider, but, sometimes it feels like their developers have never used an email client before in their life.
Now they *just* (I mean....) introduced labels, BUT you still cannot create filters that automatically apply labels too.
Gmail may be the evil to avoid at all cost, but, their UX had already everything like 20 years ago.

Tuta is good for privacy, but their UX is stuck in the '90s and it makes a horrible whole email experience. #privacy
