I talked with a mortgage professional who was very good with his database marketing. He added names over time and developed friendly HTML newsletters to email his clients, acquaintances, and prospects. The keys to his success were a non - threatening, non - salesy informative newsletter and above all CONSISTENCY. One of his clients commented at their last face to face meeting that he was the nicest pest she had ever met.
In database marketing consistency is very much a key. But being helpful in giving relevant or interesting information to the reader (kind of like blogging) is very important. He said he rarely had anyone unsubscribe from the list. That too, shows he's offering something of value and keeping top of mind the company name, the individual's name, and the company's services and contact information.
We all should be so lucky by design to be labeled a nice pest!!

Many consider this spam as there are so many of these newletters......the database idea is great though.
Pat: I would never call you a pest. You are very NICE however : )
