Across all of our events we send close to 1000 unique event properties to CIO. They offer us the unique opportunity to leverage all of these properties to further personalize our email campaigns resulting in higher open and click rates. Other tools did not allow for this and it would require expensive additional development time to get all the relevant data to be available in our campaigns.

– Lucas van den Houten, Cofounder of StuDocu
