Description: Write, optimize, and grow Substack content — newsletter issues (email-first) and web posts (web-first essays). Covers voice matching, Substack algorithm and Notes strategy, email formatting, SEO, growth tactics, and paid-subscriber monetization. Use when the user mentions Substack, a newsletter issue, a Substack post or article, evergreen content, newsletter growth, Notes, paid subscribers, 'ghostwrite for', or 'write in the style of' — and for newsletter or essay writing even when Substack is not named, or when adapting a blog post, talk, or thread into newsletter format. Do NOT use for generic blog post writing without a newsletter context — use samber/cc-skills@technical-article-writer instead.
