I recently was updating my database and needed to acquire the birthday of my past clients. I decided to send 50 of them a birthday card, even though it was not their birthday. The message simply stated: “Happy birthday and hope you have a blessed day.” Then I wrote a P.S. “If this is not your birth-day, please visit my web site and help me update your file.” Out of the 50 past clients, 21 updated their file and 6 said thank you for it was their birthday that month. Great way to keep in touch.
