The newsletter is something you can offer in addition to the normal follow ups. You can write a number of very short posts on news in the industry, summarise and provide links to the best articles over the past month, year and then add short mentions of products eg use your aweber and Bluehost affiliate links under a products I use section at the bottom.
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.
