Interactions are crucial to monitor because they tell you what worked and what didn't. Most businesses monitor the number of opens but fail to see other data such as the click rate, the trend of your subscribers in the list, their interest, their conversion into customers and more.
Spotzee allows you to see engagement based on their location and what subscribers are interested in. These interactions help predict your customer behaviour and understand them better. Understanding them better always helps in personalising campaigns accordingly.
