This document summarizes three rules of event marketing according to Hans Janssen of DenkProducties. The rules are: 1) Have goals rather than tools, and recognize that people want to improve, not change; 2) There is no such thing as over exposure if the message is consistent and content drives marketing; 3) Be original, personal and generous to make marketing stick out through guarantees even without guarantees. The document provides background on DenkProducties which plans premium seminars and online learning programs in the Netherlands.
