Send a note to your new customers 

After they’ve made the decision to purchase their insurance from you, most new buyers will ask themselves if they made the best choice.  An effective way to handle this “buyer’s remorse” (post-purchase cognitive dissonance) is to send a short, handwritten note the day after the sale.  Thank them for their business, and congratulate them on making a wise decision.  Your note should also call attention to all the ways that the new customer can contact you---by e-mail, by phone, by fax. 

I call it the first service call.  

 PS--Another good retention strategy: make sure the new customer is immediately placed on your agency newsletter list.  Making 2 or 3 contacts in the first year, including an annual review, will help cement the business.
