How is AI used in Marketing Automation?

"Technology is a great slave, but a poor master" The above line is a common phrase in any discussion involving AI. It doesn't seem that the discussion is one to be resolved anytime soon. With the concept of self learning technologies taking precedence in a digital driven world, AI finds special usage in Marketing Automation. Marketing refers to the process of promotion of a particular enterprise's products through research, analysis and interpretation of consumer data. In short, it is the art of convincing a consumer to buy something they do not need.
