The safe way to access your personal mail.

Image from store GMX.com MailCheck
Description from store With the GMX.com MailCheck extension, you only need to log in once with your GMX.com-credentials in order to gain quick and simplified access to your inbox. From then on, you merely click on the envelope icon in your browser for instant access to all of your emails (e.g. gmx.com, mail.com, Outlook Live). No more searching for your email provider in a search engine then directing toward the sign-in page, and finally entering your login details—skip all of this with easy one-click login with MailCheck from GMX.com. Enable optionally the mail preview panel in MailCheck. Delete unread mails directly from your inbox. Access your inbox for writing new mails.

  • (2021-05-01) Nutrimex Nutrimex: Hi GMX support, I've installed your addon on my Yandex browser and I cannot connect any account. The app is always asking for enter a password (what I did so). What could you advise me to solve this ? What is the problem ? Thank you for your help.
  • (2021-04-18) louis berthaut: super extension ! Utilisé depuis plus d'un an pour GMX et hotmail, et marche impecc !
  • (2021-04-14) Andy Sanz: This MailCheck comes very handy by letting me know what's going on in my mailbox.
  • (2021-04-05) Carl Miller: Won't work if you refuse to give it permission to automatically read and change data on 11 different Google/Microsoft domains. There are mail checking extensions for Yahoo, Gmail, Hotmail, and Yandex that do not require this, so I'll use other services until GMX drops this requirement.

  • (2021-01-06) Afer Etis: Υποκαθιστά πολύ καλά την εφαρμογή Gmx mail app, που καταργήσατε. Λύνει τα χέρια. χωρίς να ανοίγετε το mail σας Μπορείτε να βλεπετε πληροφορίες για τα εισερχόμενα σας και να επιλέξετε πότε θα το ανοίξετε.
  • (2020-11-20) Mad Mario: Please add an option to adjust mailcheck interval so it would refresh even faster, also it doesn't refresh often, i need to check it manually everytime
  • (2020-10-04) Audio Expedition: Love GMX mail, used it over many years now, So its pleasing to see the phone app released, together with this handy extension making email access easier, Well done.
  • (2020-09-25) Tim Bales: Todo ok,gracias
  • (2020-09-07) Robert Hawkins: After fourteen years with hughesnet we finally built a new house and upgraded our internet service provider and I needed a fast reliable mailbox to move all my email to. I've been real pleased with GTX so far. With both the mobile and browser aps it makes it really easy and convenient to keep up with several now defunct hughesnet addresses.
  • (2020-09-06) Nickolaus Pacione: I had a mail.com account since 2000, though I had no idea GMX had been in play for more than 20 years. Buying up Mail.com allows my classmate to get moved in -- the website responds differently on Android or Chrome than it does on FireFox, Edge or Apple [the latter has features that will be effective in Apple too the feature is a goto for LibreOffice 7 and higher upgrades of Open Office.]
  • (2020-07-03) Gunawan F: Easy to use
  • (2020-04-11) Star Strider: This extension indicates unread mail in my GMX accounts. When it goes to "Page Not Found," I push the "Log In" button on the right end of the menu bar, log in, and there's my mail. No problem. I like the layout of GMX online better than the GMX Android app that I also use.

  • (2020-01-05) Abby Goutal: I also get taken to a "This page does not exist" (https://www.gmx.com/logoutlounge/free_ssl?status=login-failed&site=gmx&agof=97_L&pg=null&pa=-1&pp=___NULL&region=de) when clicking on the notification. Not useful at all.
  • (2019-12-26) Daniel G: Why is it that Firefox extension has these details and Chrome extension does not? Access your data for sites in the gmx.net domain Access your data for sites in the web.de domain Access your data for sites in the gmx.de domain Access your data in 6 other domains Access your data for localhost Access your data for accounts.google.com Access your data for web.de Access your data on 21 other sites Monitor extension usage and manage themes Display notifications to you Access browser tabs - - - - - What data is being accessed from those 21 other anonymous sites? What data is being accessed to those 6 other anonymous domains? Mysterious stuff!
