If you think that personal note cards are a thing of the past, think again. Remember that feeling you got when a buddy or a family member sent you a handwritten thank you card that was actually delivered to your mailbox? I bet you got a shot of adrenaline and the feeling was amazing. I would be willing to be that your future or past clients will feel that exact same way. The power of a personal note card is difficult to understand, yet it is unquestionably, very powerful.
