Service integration is a long-term and deep integration of the partner into the look and feel of GMX or 1&1. In the process, the user remains in the environment of the portal. For example, the integration takes place through a sub-domain or interfaces such as XML. At the same time, the focus is on the added value for the user.

The partner content is also upgraded through the close relationship with the portal magazines. A proprietary navigation point, as well as the use of tools such as the drop-down menus or interactive contents, round off the partner offer.
