Substack Formatting Best Practices

Text Centering

Substack's minimalist editor lacks a standard center-align button for regular body text. To center text: select it, click "Insert Quote", then choose "Pull Quote". This creates a visual break ideal for highlighting key phrases or statistics.

Content Hierarchy

  • Use Heading 1 through Heading 3 to create a clear, scannable structure.
  • Keep paragraphs short (35 sentences max) to maintain readability in both email and web views.
  • Use Bold, Italics, Strikethrough, and hyperlinks to guide the reader's eye and improve scannability.
  • Use bullet points, numbered lists, and dividers to break up long sections.

Quotes

  • Block Quote: For clearly attributing long excerpts from external sources.
  • Pull Quote: For emphasis on a key phrase or statistic; renders centered and visually distinct.

Visuals and Media

  • Insert images, GIFs, or charts to break up heavy text.
  • Image width options: standard, wide, or full — choose based on the visual weight needed.
  • Always add a caption and alt text to every image. Alt text serves accessibility and organic SEO simultaneously.

Interactive Engagement Tools

  • Native buttons: "Subscribe", "Share your post", "Leave a comment".
  • Custom buttons: Insert any URL to drive a specific reader action (e.g., download, survey, external link).
  • Polls: Exclusive to paying subscribers; functions as a passive engagement and retention mechanism.

Email Subject Line Rules

  • Keep subject lines under 50 characters to prevent truncation on mobile.
  • Avoid ALL CAPS, excessive exclamation marks, and spam-trigger phrases like "Buy Now" or "Act Now".
  • Test deliverability by checking spam scores before sending to the full list.
