One of the best ways to show your business cares and provides personalized attention is to send a handwritten thank you note. I have found this to be a lost form of communication because technology has made it too easy to simply send a quick email or an e-card. Taking the time to handwritten a note let's your clients and potential new clients know your company is serious about your business relationship. It also separates you and/or your business from the multitude of gift baskets, cupcakes, fruit and sugar cookies sent to clients. It also allows you to get back to the basics.
For one, it's satisfying. Being able to express feelings clearly and concisely on paper is rewarding. Second, it's personable. You have to come up with the message unlike a card bought in a store or pre-made online. Third, it shows you care because time was taken to sit and pen a message.
Make it a priority to show your clients, business partner/associate, and employees how much they mean to you (although, this is a blog and typed on a computer #irony.)
