About the OpenEMM

The OpenEMM is the first open source application for professional email marketing. The code base has been developed since 1999 and is used in the commercial version by companies such as Conrad Electronic, DEVK, e.on, Freenet and Otto Group companies.

A completely new OpenEMM version has been available since 2019. This version is at the same development stage as the commercial software E-Marketing Manager. If you upgrade to E-Marketing Manager, only the functionality changes for you, but not the user interface. This makes the transition very smooth and easy.

Die Software bietet bereits jetzt mehr als 90% der Funktionalität, die eine Vielzahl der kommerziellen Produkte enthalten. Einige OpenEMM-Features bieten selbst die meisten kommerziellen Produkte aktuell nicht an, zum Beispiel MySQL-Support und eine Plugin-Schnittstelle.

The main difference to the EMM, which which is charged with varying costs, is that the OpenEMM is a simple single server solution. Whereas the EMM offers a larger range of functions with several channels and is operated on several servers for better performance. In the Software as a Service (SaaS) version of the EMM, in addition to an extended range of functions, you also benefit from the CSA Whitelisting.

On our website you will find some categories with free service and support, for example FAQs, OpenEMM Forum and the Download Center for the OpenEMM. The content is continuously updated with feedback from the OpenEMM community.
