Brian Clark of CopyBlogger, Genesis WordPress Themes, and the Further personal development newsletter has a simple free course called Next 7 that he says “can lead to a 7-figure business without employees or investors.” It is delivered by email after short quizzes for each lesson. I find the process a little annoying, but it might be a good strategy to encourage people to complete a series of emails. It ultimately leads to information on his upcoming course on the subject. Despite the promotion, it’s still interesting. The main idea is that email newsletters of curated content are a big business opportunity in our world of information overload. Obviously, that is the premise of starting this IdeaEconomy newsletter so I’m biased on the topic. 🙂
