Sales Letter Writer
Teach Claude to write long-form direct response sales letters using the methodologies from Gary Halbert's "The Boron Letters" and Dan Kennedy's "The Ultimate Sales Letter". It walks you through customer research, finding your big idea, headline formulas (how-to, secrets, warnings), and the classic sales letter structure with specific proof elements. Works for landing pages, VSL scripts, email sequences, or traditional direct mail. The skill includes headline templates, copy flow patterns, and the Halbert principle that market matters more than copy. Good for copywriters, course creators, or anyone selling through persuasive writing who wants proven frameworks instead of guessing at structure.
