SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve? Writing Substack content that grows subscribers requires platform-specific knowledge most writers lack: email client rendering limits, the subscription-optimized algorithm, Notes strategy, SEO fields, and voice matching for ghostwriting. This Skill encodes that expertise into a structured workflow so drafts are formatted, optimized, and on-voice from the start. ## Core Features & Use Cases - Dual-format writing workflow: Handles both newsletter issues (email-first, subject lines, preview text, short paragraphs) and web posts (SEO title, meta description, URL slug, evergreen strategy) with distinct formatting rules for each. - Ghostwriting voice matching: Extracts voice markers from transcripts, talks, and writing samples to build a validated voice guide before drafting in someone else's style. - Growth and monetization guidance: Applies Substack algorithm mechanics, Notes testing pipelines, Recommendations strategy, and paid-tier timing advice based on subscriber count. - Use Case: A founder asks you to ghostwrite a newsletter issue about their Series B journey. The Skill first collects voice samples, builds a voice guide, interviews for topic and audience, proposes titles and hooks, then drafts an email-formatted issue with a Notes teaser and optional LinkedIn/Twitter distribution posts. ## Quick Start Ask the agent to write a Substack newsletter issue or web post on your topic, and answer its intake questions about audience, objective, format, and voice.

Frequently Asked Questions about substack-ghostwriting

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I write a Substack newsletter that grows subscribers?

Focus on content quality since Substack's algorithm optimizes for subscriptions, not engagement. Use a specific 6-10 word subject line, a hook in the first 2-3 sentences, short paragraphs, and end with a reply prompt. Recommendations from other publications are the highest-impact growth lever.

How do I ghostwrite a newsletter in someone else's voice?

Collect 3-5 voice sources prioritizing transcripts over edited writing, extract voice markers like sentence length, vocabulary, and humor style, then build a voice guide with 10-15 markers. Validate the guide with the client before drafting, and never anchor on a single source.

What is the difference between a Substack newsletter issue and a web post?

Newsletter issues are email-first: short 2-3 sentence paragraphs, subject line and preview text, code under 10 lines, and minimal images. Web posts are SEO-first: separate SEO title and description fields, keyword-rich URL slugs, longer code blocks, and reliable embed rendering.

When should I launch a paid tier on Substack?

Avoid paywalling below roughly 1000 subscribers since growth compounds faster than paid conversion at small scale. The industry baseline free-to-paid conversion is about 3%, so early revenue is minimal. Consider coaching, consulting, or products as alternative monetization first.

Why does my long Substack email get cut off in Gmail?

Gmail truncates emails exceeding about 102KB, which is roughly 3000 words with formatting. Keep newsletter issues under that threshold, add a TL;DR for issues over 1500 words, and link to Gists for long code instead of embedding it inline.

Can I upload videos to Substack Notes?

No, Substack Notes does not support video uploads. Notes support text formatting, mentions, up to 6 photos or GIFs, and links. Use a GIF, screenshots, or a link to externally hosted video instead, and keep Notes concise at 2-5 sentences.
