When going over the designs for his website, a client of mine said, "If we put our newsletter on our website, why do we need to e-mail it to people too?" My answer: "Because they don't know it's there!" It's a very common question, and a common misconception. Just because you build a website doesn't mean that anyone knows it's there. And it's not a guarantee they'll come. In fact, people are fickle. You have to beat them over the head to make them visit your site, and then you have to make it easy for them to read your site, navigate your site and anticipate what they're looking for.
