Marketing management is a business function concerned mostly with acquiring customers at scale. Marketing managers grow the profits of a firm primarily by increasing the quantity of products sold, but also by adjusting the price at which those products are sold:
Profit = (Price-Cost)*Quantity
In theory, marketing managers could grow profits by getting existing customers to buy more. Research, however, has shown that loyalty programs are not generally as feasible or as profitable as acquiring new customers. This goes against the conventional wisdom that it is cheaper to keep a customer than to acquire a new one.
