By using email as a marketing tool, you can contact your web/blog visitors (who are not yet buyers) and give them more reasons to consider becoming your customers. You can give them more information, supporting facts, and proof that what you claim the product will do is true - basically, educate them about your product's true value. Of course, they can always unsubscribe. But those that don't are interested in your information or offer.
If you want to dramatically increase your sales, using follow-up email is a must. It enables you to find the right buying time for customers. It may be two days, two weeks, or even two months from now. Either way, you can be there to help them when they're ready.
To capture the email address and build up a database of thousands people, you will need an effective list management software, and it is going to become a very important part of your internet business. I would recommend an easy to use software called GetResponse, which offers a 30-day free trial.
In the following video, I will show you how to design a web form and integrate it with your blog, so that you can start collecting email addresses today.
