I use them too. Their web ui and app are totally ugly crap but if you use it with thunderbird or another mail app it’s good.

Just switched and couldn’t be happier. Now I can use FairMail as a client and loving all the extra features.

I used a custom but generic sounding domain name which made the switch pretty seamless.

I’m only missing tag support on emails from them. In my ever growing archive, I came to realize, that tags are better suited for organizing than folders.

Ideally I would archive in yearly folders and also tag as much as I can.
