Every publication exposes a full feed at /feed.
Quick answer
https://[publication].substack.com/feedContext
Substack publications are built on a standard template and every one of them exposes RSS at /feed, whether the publication lives on a substack.com subdomain or a custom domain. Paid posts are paywalled in the feed: they include the title and short preview, but the body is replaced with a subscribe prompt unless the reader is authenticated.

FAQ
Yes. Every Substack publication exposes an RSS feed at /feed. This works on substack.com subdomains and on publications with custom domains.
Free posts are typically full text. Paid posts appear in the feed as truncated previews with a subscribe link, regardless of the publication's other settings.
Add /feed to the publication's root URL. For example, https://www.noahpinion.blog/feed works even though the site does not use a substack.com subdomain.
Only as a paying subscriber. Substack does not provide a way to retrieve paid content through RSS without authentication, and attempting to scrape around it violates the platform's terms.
Substack publishes roughly the 20 most recent posts in a feed. There is no pagination, so older posts are not accessible through RSS.
