Among the many interesting features that GMX Mail offers, you'll find the possibility of setting up a silent time frame in which you won’t be notified of any emails you’ve received. This feature can be especially useful when you’re out of the office and you don’t want to worry about work emails.
Another interesting feature is that you’re able to set up a PIN for your inbox. This option makes sure that no one else can read your emails if for some reason you misplace your smartphone.
GMX Mail is an excellent option for Android which offers you a wide range of features and a clear and easy-to-use interface.
