I have not really used them, although I have their cheapest account hanging around. Not able to make a recommendation, but maybe someone else can comment.
They offer a bunch of extra stuff like cloud, video conferencing, calendar etc. but I’ve never touched it.
In my opinion the interface is terrible and the settings are not so user friendly, in the settings menu is a kinda sub-settings menu which seems to be embedded from a subsystem…? But if you’ve got everything setup and provided you’re using your own email client, the service is top notch.
Never had a problem, maintenance and stuff like this was always communicated clearly and early. They split the parent company behind mailbox.org into its own one and even this one was very nice communicated.
I’d love to try providers like Purelymail because I think 30€ per year for my few mails is a bit overkill but the money is well spent on people knowing what they are doing and most important, the servers are all hosted in Germany.
YMMV but I’m happy with them and would definitely recommend them!
For basics they are fine. Their cheapest plan is not the old cheapest. They added some new plans and now on cheapest plan there's literally no support (not even email or ticket) and many features simply cut off - no personal domain either.
IMHO one must not consider a paid email provider if it doesn't support custom domain, no matter how cheap that plan is.
UX is pathetic and there's no sign of that being fixed.
