Here's a simple way to use postcards to attract new customers. The next time you're at an industry convention, buy 25 postcards that represent the place you're visiting. Think of a clever headline that ties in with the picture on the card. For example, a real estate agent sent a Nashville postcard that showed horses running though a pasture that has a headline reading, "Don't horse around when you want to sell your home fast."
Write a brief message telling your prospective customers that you're attending the industry event to learn how to better serve them. Let them know you'll be in touch when you return, and when you do, start making follow-up calls.
