What content management software (CMS) are you using? It should have it's own "Newsletter Subscription" widget that you can add/download/plugin to the side of every page on your site -- giving you a simple, low-cost, call-to-action that drives e-mail subscribers every time you have a visitor.
Once you have an e-mail list you can use it to not only drive more traffic to your website, but you can use it to send affiliate product promotions (that allow email traffic) as well. Because of this I would suggest getting something like this on your site ASAP because you definitely want to start building your list as quickly as possible.
Hopefully this helps. Let me know if you (or anyone else) has any further questions, comments, or concerns.
