The wave of CRM is CDP. Customer Data Platform. The key is that it isn't just your basic account data, but all the behavioral data across various system interactions both online and off (if applicable). Shopping Cart abandonment email campaigns are pretty benign. But the outrage around the targeted ad for baby/pregnancy products that made the news from Target a few years ago is just the start for what more insightful data signals can give you. I don't really care about most retailers knowing what I buy. I do care about them reselling that data to big aggregators that know everything I buy, where I go and when, and join that what sites I visit and what mail I get. It is too much and can be abused.
