A company called Cinnabar was heavily into all kinds of technology to stay in touch with clients. The systems worked great, at first. When the company's booming business began to drop off, the President discovered that face-to-face interaction with clients was an extremely important part of the communication process. He asked his people to pay personal visits to clients. The results were a 50% growth in business within a couple of quarters after the change.
So, emails and websites are great, but don't forget to build the person-to-person contact into your company's communication mix.
