Marketing is all about the customer. The more you understand each customer and their preferences, the easier it is to engage them with individualized messages, offers, promotions, and even individualized prices and products. Machine learning empowers marketers to use the growing volume of customer data to gain deep insight into customers and markets – insight far beyond what marketers could gather via their intuition and/or simplistic analyses like recency, frequency, monetary value (RFM). This insight can then power relationship-building strategies that build customer loyalty, advocacy, and brand value.
