About this plugin
Feed Embedder for Substack lets you display the latest posts from any public Substack newsletter anywhere on your WordPress site using a simple shortcode:
[fefs_feed]
g. com ) in the settings — the plugin derives the RSS feed automatically, fetches your latest posts and renders them as clean, fully customizable cards.
Features
- Simple shortcode — drop [fefs_feed] into any post, page or widget.
- Per-instance overrides — [fefs_feed url="https://other.substack.com" count="4" layout="vertical"].
- Two layouts — horizontal cards (image beside text) or a vertical grid with 1–3 columns.
- Full design control — colors (with color pickers), font sizes, weights, spacing, borders, radii, paddings, gaps, hover effects.
- Live preview — see your feed with the current design settings before saving, right in the admin.
- Mobile-friendly — configurable breakpoint, stacking behavior and mobile title size.
- Smart caching — feed responses are cached with WordPress transients (configurable, 0–1440 minutes).
- Privacy-friendly and lightweight — no external scripts, no iframes, no tracking; only the public RSS feed is fetched, server-side.
- Translation-ready — all strings are internationalized.
Usage
- Go to Settings → Feed for Substack.
- Enter your Substack or RSS feed URL in the Feed tab and choose how many posts to show.
- Style the cards in the Design tab.
- Check the result in the Preview tab and copy the shortcode.
- Paste [fefs_feed] anywhere shortcodes are supported.
Shortcode attributes
- url — override the Substack or RSS feed URL for that instance.
- count — override the number of posts (1–20).
- layout — horizontal or vertical.
External requests and privacy
To display your posts, the plugin fetches the public RSS feed from the Substack address you configure. This request happens on your server (not in the visitor’s browser) and the result is cached. Post images are served from Substack’s CDN, so visitors’ browsers load those images directly from Substack, exactly as they would when visiting the newsletter.
No other data is sent anywhere, and the plugin does not add any tracking, analytics or third-party scripts.
