LAW OF 29

An unwritten law used by some marketers, which explains that on an average, the customer won’t buy a good or service until the commodity has been exposed to a promotional marketing message 29 times. While the number differs, the Law of 29 advocates believe the "in your face" style is the best way to attract customers to buy a product or service. The law is the idea behind drip marketing, a direct marketing approach of sending several marketing messages to potential clients within the certain period.
