You want to stay in touch with your customers. (Or as Jack Nicholson might say, "You need to stay in touch with your customers.")
The reason is simple: You want to turn transactions into ongoing relationships.
But that's not easy, especially when all you can think to do is send a "Thinking of you—hope you're doing well!" email that sounds like you're just fishing for business.
Want to stay in touch with customers without seeming obvious or gratuitous? It's easy. The key is to stay in touch in a meaningful and memorable way.
