In my previous post I Need A Website, I mentioned the importance of your web site collecting contact information. One of these pieces of information is an email address. The reason for this is so you can send periodic emails to your prospective customers. The reason you do this is so you can build a relationship with them. Then when they’re ready to buy what you sell you’ll still be fresh in their mind, they will feel like they know you and will be more likely to buy from you. Here is a video by Aweber, which is the auto responder I use, that will explain the importance a little more.
