2: Promote Your Newsletter on Your Site
Place a "Subscribe" box on your home page and a way to subscribe on every page of your site. It doesn't have to be in your main or secondary navigation. Your newsletter promotion can look like a small banner ad on your web pages, touting the value of your newsletter to whomever and from wherever they reach your web page. Also add an opportunity to subscribe at the end of your checkout process. If you require a free registration for visitors to personalize their visits to your site, include an opt-in for your newsletter there, too.
