Don't Forget to Market to Your Most Important List!
In it, Levinson suggests you market to 2 lists ... your customer list and your prospect list. He considered the customer list to be the most important. Why? Because these people have already purchased something from you ... which makes them at least twice as likely to buy something again!
He suggests you pay the most attention to this list and treat the people on it like royalty. Something I'm going to pay a lot more attention to in this down economy.
