GMX is a subsidiary of United Internet AG, a publicly-traded German software company. It provides a host of online consumer software tools, including a news portal, cloud backup, file sharing, and the email service we’re reviewing now. GMX, the company, was founded in 1997 and soon after established itself as a leading local email provider in Germany. In 2007, it launched an English language version of its email service called “ GMX Mail,” targeted at users outside Germany. GMX Mail has been very successful, serving around 20 million users worldwide. We tested GMX Mail rigorously to give you a detailed, impartial review. Our review is based on specific criteria, including features, pricing, ease of use, customer support, security, etc. GMX Mail is completely free. It makes money from advertisements rather than charging customers directly. GMX, the company, offers paid email packages with stepped-up features than GMX Mail, including GMX ProMail and GMX TopMail. However, they’re explicitly for German users, not English-speaking foreigners. GMX Mail offers many features to give you a sound email experience, including; GMX Mail provides 65GB worth of email storage to every user. That’s enough to not worry about running out of storage space for some decades, at least for normal email users. For comparison’s sake, Gmail and Outlook offer 15GB of free storage. There’s no good email service that won’t let you attach files to send to people or receive such files. GMX Mail lets you do that, but the maximum file size attachable is 50MB. This size limit may seem small at face value, but consider that a formidable rival like Outlook allows just 20MB and Yahoo Mail 25MB.
