Feed Embedder for Substack

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]

Just paste your Substack address (e.g. https://example.substack.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.
