If you own an online business, you want your visitors to come to your website frequently and buy products from you. One of the most effective methods of attracting potential customers is to obtain their email addresses. Many online entrepreneurs believe that if you can gather the email addresses of your visitors, you are on the right track to make your business successful. If you look closer at your website, you will see that most visitors coming to your website do not make a purchase during their first visit. If you have a chance to capture the email address of your potential customer, then you will have a greater chance to earn money. By sending him a newsletter you will be able to remind him of some great offers on your website. If you would like to capture email addresses, remember to do it the right way. For example, if you offer a free eBook, you can ask your visitors to give their email details in exchange for a free eBook. Do not be deceitful and always offer your visitors to unsubscribe from any newsletter you may want to send to them. After some time, you might acquire emails of a lot of visitors and because of this your website might benefit a lot.
