Doing business on the Internet means having to deal with hundreds, or thousands, or even millions of surfers.  And most of the surfers are impatient - aware of the fact that for each product, there are thousands of retailers with thousands of variations and options. Generally, the potential customers are in a hurry to do something or to go to some other site. But, while they are on your site, you can have them agree to receive a periodic eMail to provide them with useful information about your product and related topics that can benefit them.

This is where the power of communication lies. Once they are ready to give their eMail address to you, it means they are interested in dealing with you, they are not wary of hearing from you.

We generally get attached to people with whom we interact. Those people get imprinted in our subconscious, and if those people are likable, gain our respect and trust, we like doing business with them.
