Substack

This tag covers Substack, the newsletter publishing platform, and the distinction between its RSS-powered newsletter posts and Substack Notes, its separate short-form social feed. It explains how every Substack publication's standard RSS feed can drive automated social posting, while Notes has no equivalent public API or RSS trigger available to third-party tools. Readers here are typically Substack writers trying to understand what can be automated around their publication and what still requires native, manual use inside the Substack app. It also covers practical setup details like custom domain feed URLs and how paywalled content appears differently in the feed. This is useful background for anyone building a distribution strategy around a Substack newsletter.
