How Can Machine Learning Impact the Success of Marketing Campaigns?

Machine learning is not a new phenomenon. It has co-existed silently for years and has made noise only recently. Take for example the act of looking up things online, using a search engine. This is possible because of the underlying machine learning principles that are at work here. But, that does not mean that it is still the same at this point. What I want to say is that machine learning has improved since then, and is advancing at a swift pace.
