If you want to be sure that people see the opt-in form on your website, have it jump out at them as a pop-up window. This feature, which is simple to install, allows visitors to your site to enter their e-mail address the moment they enter your website. You goal, after all, is to capture e-mail addresses, and pop-up windows can help you do this. One reason to comply with the instructions is simply to make the form disappear. The other side of this, however, is that many internet users hate popup windows. Not only won't you get the e-mail addresses of people like this, but they will tend to simply click away from your site when they see a pop-up. You have to decide whether you think using a pop-up would help or hurt your overall chances of capturing e-mail addresses.
When people come to your website, their should be an easy way for them to fill out their e-mail address and any other information you want to ask for. Place an opt-in form somewhere on the page where visitors can't miss it. It should not be hidden by other details or information. Don't place it only on one page, but on every page you publish on every site that is related to this niche. The more complicated it is to sign up for your mailing list, the more likely it is people will click away before doing it. If you make it easy, however, you will probably end up with more e-mail addresses than you know what to do with!
Always avoid the temptation of mailing too often. Too many emails feel like spam, and they'll grow to resent your presence in their inbox, and you know what that means. People will listen to you if your email frequency is right, and you offer them helpful information. You can have a good reputation for solid content, and then people will hear because people talk, and you will gain new subscribers all the time.
Once you put your mind to it, you'll find that you can build your e-mail list in many ways. Try different methods and find out what works best, and your list will keep growing! Just as you have to promote a blog, website or affiliate product, you have to do the same with your e-mail list if you want it to grow. You have to be patient, as building a good list takes some time to achieve. Once that list is built, however, it can be a profit goldmine!
