Why this can grow a startup

A newsletter welcome page often wastes the highest-intent visit on a generic hero image and one sentence of self-description. Substack lets publishers add recommendation blurbs from other creators directly onto that page. That changes the trust surface from self-assertion to borrowed proof. A new visitor can see why other writers recommend the publication before they have read enough issues to decide alone.

Source-backed example

Substack says publications that have recommendations enabled can add up to three endorsement blurbs from other recommending creators to the Welcome page shown to new visitors.

When to use it

Use this when Substack, Brand, Conversion is relevant to welcome page, social proof, creator trust and you can run a bounded test with a free budget.

When not to use it

Do not use it as a substitute for customer evidence, a clear owner, or a measurable stop condition. Local platform rules and market behavior still need checking.

How to do it

  1. Choose one target segment and define the exact next action this tactic should prompt.
  2. Adapt the tactic to Substack and Brand, using evidence from Substack Support: How do I add an endorsement to my Substack publication? as context—not as a promised result.
  3. Record a baseline for: Target users who complete the tactic’s intended next action. Set a guardrail that would make you pause the test.
  4. Run a narrow pilot and choose a test window that fits the normal decision or use cycle; do not scale before you have observed the full cycle.
  5. Compare the signal with its baseline. Scale only if the intended action improves without crossing the guardrail; otherwise revise one variable or stop and record what you learned.
