Fantastic Funded Proposal

A more specialised subject than most on this list, and that is its advantage: a funded proposal is something your customers have heard of and few understand.

Fantastic Funded Proposal explains the idea and how to use it to improve conversions, written by someone who found it confusing themselves, which makes the explanation more patient than most.

Sell it to customers already running offers who want better results from the same traffic, rather than to beginners who have nothing to apply it to. It is a natural companion to One Time Offer Blueprints and Product Funnel Optimization, since all three are about earning more from each visitor rather than finding more of them. Because the subject is unfamiliar to most readers, lead your email with the problem it solves rather than the name of the technique.
