This is a production-level ghostwriting skill that treats Substack as what it actually is: a social-media-newsletter hybrid with subscription-driven incentives, not a blog with an email bolt-on. It walks you through voice matching first (sample collection, marker extraction, validation), then forces an intake interview before drafting anything. The workflow splits cleanly between newsletter issues (email-first, subject line optimization) and web posts (SEO-first, evergreen articles), with dedicated formatting guidance for each. What I appreciate is the brutally honest framing on ghostwriting: you're extracting insights from clients who have them but lack time, not generating thought leadership from scratch. If you write for founders or execs on Substack, or run your own technical newsletter, this gives you a repeatable system instead of winging it every week.
