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.

Frequently asked

Does this just generate pretty charts or does it actually tell me what to do next?
Both. You get the trajectory and forecast visuals, but the skill closes with a concrete top-3 experiment list — specific tactics matched to your subscriber tier and funnel stage, with platform-specific steps for Substack or Beehiiv. Not 'grow your email list' advice.
I don't track my growth channels at all — can I still use this?
Yes. Tell it what you don't know. The skill uses benchmarks from its bundled data to fill gaps and will flag which numbers matter most for you to start tracking. The 'I don't track any of this' example prompt is literally in the use cases.
Will this work for a newsletter with no paid tier yet?
Yes — it handles free-only newsletters and factors that into the experiment recommendations. It'll still give you a paid conversion forecast for when you're ready, and the growth experiments will be weighted toward list-building rather than upgrade conversion.
Can I just write a prompt myself instead of paying for this?
You could try, but the skill bundles four reference files the prompt alone can't replicate: benchmark data by subscriber tier, an 18-experiment library, channel attribution splits, and platform-specific Substack vs. Beehiiv notes. A freehand prompt gets you generic advice; this gets you numbers compared against real benchmarks.
Does this work on Claude, ChatGPT, or both?
This is a Claude skill — it runs inside Claude.ai and uses Claude's artifacts feature to produce the formatted dashboard output. It's not compatible with ChatGPT.
