When it comes to deploying targeted marketing differentiated by customer/consumer segment you don’t have to worry as such about the fact that you need different messaging to be effective. Keep in mind that brands reach different audiences through distinct media or locations, if you will. For example, Coca-Cola has to speak to several audiences (e.g., consumers, investors, distributors, institutions, etc.). Coca-cola uses a distinct, relevant messaging for each audience. When was the last time you, as a consumer saw Cova-Cola marketing that was meant primarily for investors or distributors or institutions? Without the distinct messaging, Coke could not speak effectively to each audience, but because each audience is distinct the differentiation in messaging doesn’t cause confusion. Otherwise put, I think what is important is one audience-one message, not so much one product-one message.
