I love Aweber! Have been using them for about a year now. I still use Feedburner for subscribers but I use Aweber for my newsletter and five-part drip campaign. It’s worked well for me and my readers are highly engaged. In 2010 I did a short e-course and that worked well. The next step for me is to find ways to create more ever-green content and build it into the newsletter and think about another ebook for sale (as in the process you described) or another e-course.
Even if you've imported an existing list of contacts, you'll still want an easy way for new fans to join your email list. AWeber's sign up forms provide the perfect solution. Create a simple sign up form for your website, and if you don't have a site, we'll host it for you. Grab the link to your AWeber form and share it on Facebook, Twitter, LinkedIn, or wherever your audience is.
