Businesses and Trillions of dollars are built and made from marketing tips and strategies.
Customer focus is first. Answer the need ("What's in it for them"). Then,
give them a reason to come back for more (i.e. opt-in). After that,
make them feel important (which they are), and give them offers and
opportunities that they would be "Crazy" to pass on. But, be sure to
deliver much more that the customer expects.
