How to Create a Subscribe Via Email Link Widget for Your Blog
Feedburner offers quick and easy code or widget generation to help bloggers manage their subscriptions. Not all blog readers like RSS feeds and "readers." Many prefer a simple email notification when new posts are available.
Once a blog has been "burned" or submitted to Feedburner to distribute update notifications, tools are provided (with just a few clicks) to help bloggers create links or forms that readers can use to subscribe to blog post updates via email.
