What it does
You're writing your newsletter every week, watching the subscriber count tick up, and doing the math in your head — but you don't actually have a clear picture of where you're headed or what's working. This skill turns your raw numbers into a newsletter growth funnel dashboard in a single conversation. Paste in your current subs, weekly growth rate, open rate, and paid conversion (or whatever you actually know — it handles missing data). The skill runs three passes: a subscriber trajectory that shows you exactly when you hit your next milestone at your current pace, a growth-channel attribution table compared against benchmarks from the bundled `channel-attribution-benchmarks.md` and `industry-benchmarks.md` files, and a paid conversion forecast with MRR projections at 3, 6, and 12 months. Then it closes with the top 3 experiments from the curated `growth-experiments-library.md` — 18 experiments organized by funnel stage and subscriber tier — with platform-specific instructions drawn from `platform-specific-notes.md` for whether you're on Substack or Beehiiv. Built for newsletter writers at 100–10k subscribers who are past the 'just keep publishing' stage and want to grow the list with intention. Works whether you're a spreadsheet person or someone who has never tracked a single metric in your life.
