Deliver Value With Each Follow-Up
Calling a customer just to check in or to make sure they got your last call or e-mail is a bad idea. Not only are these calls irritating, they do nothing to build a relationship with the customer. You need to have a compelling reason for the call, such as an important update about their quote, something you forgot to mention before, or a great success story from another client you feel applies to them.
For example, you could say: “I was thinking about another customer of mine who was in a very similar situation as you and [how your agency benefited them] and I thought you might find that information helpful.”
