In-app messaging. Email sends. Content creation. There are so many things that we do to promote different features of our product. But after awhile, users tend to tune them out especially if they are not relevant. It can be challenging if not impossible to figure out how to re-engage your customers especially when you have a new product that would benefit them. Using usage data from SQL or MixPanel, you can cater your messaging toward the segment of customers who are a great fit for your latest product release or your latest product marketing campaign. In this session we will walk through how to do this through developing a hypothesize, pulling usage data in SQL, and running a campaign based on this data.
