GMX Reviews 

The new UI is terrible, Unread emails and Inbox count are tied to each other (broken).

Unless there is a back-end performance, logistics, or capacity issue - revert back to the previous UI version.

Customer Service does not appear to exist to provide this feedback to.

The new email interface is unreadable and customer service appears to be non-existent.

The new webmail page which changed this week 8th June 2026 is absolute rubbish, please return it to the previous version

Used GMX for many years. Never had a problem until yesterday afternoon. Without warning, their email layout totally changed within minutes from the usual professional and easy to use layout, to something looking like a kindergarten or disney layout for children, plus extremely clunky and difficult to use. No warning, no explaination given, and no reply from 'customer service', which appears to be non-existant. The new layout cannot be changed either, so you are either stuck with it or have to change email provider. I am not happy with this treatment from an essential provider.

The new interface, hate it, why cant you just let things be, the old interface was fine!

Worst email ever! The captchas are stupid. You can do it right a thousand times, and you still can't get your account started. It doesn't autosave passwords in your phone: in other words, even if you have a password that you've used before, it is always incorrect. I finally gave up and went somewhere else. Why go through the trouble to try to set up an account only to be told you can't get one?

They delete your email account while there is activity on that account. Al data lost. NOT TO TRUST

TERRIBLE SERVICE
Worst email ever. A lot of time it won't even load. My partner is locked out of hers for some reason and 'CUSTOMER SERVICE' IGNORE literally dozens of emails from her. They expect people to pay for this?! I would NEVER give them a penny! Did the same thing to me and I had to pay someone to hack into it to get access!!!

Had an account for years without one single issue and had always used the same password but now suddenly my account was blocked by gmx (probably due to my vpn which is unacceptable in any case) and was FORCED by them to change my password to something of 12 characters, it wouldn't accept anything less, which now throws my password system out of wack and I insist on CONTROLLING MY OWN D**D PASSWORDS!

This makes me look for an alternative and just CLOSE the account with gmx because this is ridiculous. They have no right to force me to use a 12 character pw when my 9-character pw has always worked before. Worst thing? There was absolutely NOTHING WRONG in my account, the "suspicious" activity WAS MYSELF, brainiacs.

I'll be out of their hair very soon, looking for a solution as of NOW. They would deserve zero stars if that was an option. Still hoping for that option on trustpilot beceause it is NEEDED for some of these companies and providers.

In UK, I cannot even pass registration stage after 2 days of clearing cookies, cache, browsers, VPN, WiFi, etc.
They obviously don't want new customers, try a different email provider

Blocked my account after one week and 3 emails. Despite contacting them it is still blocked. I wish that I had read the revues in here before I signed up.

Like many others I find I have been locked out of my account as my username/email address is not recognised even though colleagues are still sending messages to that address. The help desk just claims they are overloaded and have provided no solution. I wish I had never used them and will take my email elsewhere.

GMX has zero customer support. Used it for years through Apple Mail, until it was unable to connect to the server. So the only way for me to access my email is through a browser. Very disappointed.

emails take a long time to load. spam filter not working properly.

0 stars, worst service in the world. They blocked my business email account and don't respond to customer support emails. I've been ignoring them for a month!!!

Have to say i have had no problems with this this website good experince with this website

Absolutely disgusted by them locking my friends account and making his business suffer . All he ever did with this email provider was to send emails between clients dealing with his real estate. He is now moving away from this rubbish provider and i wanted to warn everyone else . DON'T USE THEM. They don't even reply to any message sent to their customer services. I have warned you . PROTON EMAIL IS BRILLIANT

I have been using gmx.com as my email address for many years until one morning I was no longer able to access my account. I am therefore unable to receive any emails and have lost everything in that account. I have filled in their form for customer support over 10 times and have not heard back from them. I have also written to their Karlsruhe address. Again no response. Really disappointing and would not use them again.

gmx account may seem to work for a while but then you will get a problem and thats it, no support

it will lock you out your account or not let you log in
so do not use them for important email needs as you may not be able to get in your account one day and they will not help you.

I've never encountered anything like gmx mail. I opened an account several weeks ago, and after moving all of the mail I had saved from a different account, they blocked me for, " irregular activity", or something like that. It was very hard to find a way to contact them, but AI led me to the contact form. They did not so much as acknowledge my message, and its been several weeks now. No response, nothing. My important documents are locked in that account. I would say AVOID GMX EMAIL. What a shame that they do this to people. I have never dealt with anything like this before.
