Substack RSS Feed URLs: Full List + Embed Guide (2026)

Substack RSS feeds: the short version

Substack makes RSS pleasantly consistent: virtually every publication exposes a feed at /feed, and the same pattern works whether the newsletter lives on a substack.com subdomain or a custom domain. This guide lists the Substack RSS feed URL formats that work, the common variations that fail (often with a quiet 404), and a practical embed workflow for showing a Substack feed on a WordPress site in 2026.

What a Substack RSS feed is (and why you’d use it)

An RSS feed is a machine-readable stream of recent posts. For Substack publishers and site owners, a feed can help you:

• Syndicate posts to your website, an aggregator, or a company intranet.
• Republish previews on WordPress while keeping the canonical article on Substack.
• Automate content curation across multiple newsletters.
• Boost discoverability by making content easier to follow in RSS readers and feed directories.

Substack RSS feed URLs that work (tested patterns)

In most cases, there’s only one URL you need. Use the patterns below exactly, replacing the placeholders with your publication details.

1) Standard Substack domain (most common)

Pattern:

https://PUBLICATION.substack.com/feed

Example:

https://examplepublication.substack.com/feed

2) Custom domain (publication uses its own domain)

Pattern:

https://CUSTOMDOMAIN.com/feed

Example:

https://newsletter.yourbrand.com/feed

Note: This remains true even when the publication is “powered by Substack” behind the scenes. If the homepage is on a custom domain, the RSS feed is typically on that same domain at /feed.

3) Publication hosted under a subdirectory on a custom domain (less common)

Some setups route Substack through a path. If the publication homepage lives at a path, the feed is usually under that same path.

Pattern:

https://CUSTOMDOMAIN.com/PATH/feed

Example:

https://yourbrand.com/newsletter/feed

Substack RSS URL variations that often fail (quiet 404s)

These patterns are frequently assumed to work because they’re common in other platforms (or in older blog ecosystems), but Substack publications typically won’t serve feeds at these endpoints.

• /rss (e.g., https://publication.substack.com/rss)
• /feed.xml or /rss.xml
• /atom or /atom.xml
• /posts/rss or other nested feed paths

If you see a 404, don’t assume the publication has “disabled RSS.” On Substack, RSS is typically present; the issue is almost always the URL pattern.

How to find a Substack publication’s feed URL in seconds

If you don’t know whether a publication is on a subdomain or a custom domain, use this quick method:

1. Open the publication’s homepage in your browser.
2. Add /feed to the end of the homepage URL.
3. Load the page. If you see XML, you’ve got the correct RSS feed URL.

Tip: If the homepage ends with a trailing slash, both /feed and feed often work, but the safest format is to keep a single slash: https://domain.com/feed.

What you’ll see inside the feed (and what it means)

A Substack RSS feed generally includes:

• Title and link for each post
• Publish date
• Excerpt or HTML content (varies by publication settings and post type)
• Author/publication metadata

If you’re embedding the feed on WordPress, this determines how much text appears on your site. Some feeds provide full content; others provide partial content with a link back to Substack.

Embed a Substack RSS feed on WordPress (practical guide)

There are two common approaches: a built-in WordPress block/widget (fast but limited) or a dedicated RSS aggregation plugin (more control, better SEO options, and automation).

Option A: Use WordPress’s built-in RSS block (simple)

1. In WordPress, go to the page or post where you want the feed to appear.
2. Add the RSS block (in the block editor).
3. Paste the Substack feed URL (for example, https://publication.substack.com/feed).
4. Choose how many items to show and whether to display the author/date.
5. Publish or update.

Limitations: Styling options are basic, importing is not stored as posts by default, and you have less control over excerpts, images, and templates.

Option B: Import the Substack feed as WordPress posts (best for ongoing syndication)

If you want Substack posts to appear as native content on your WordPress site (with categories, custom templates, search indexing, and internal linking), importing via an RSS aggregation workflow is usually the better fit.

Recommended workflow:

1. Copy the feed URL: use the correct Substack pattern (/feed).
