Substack endorsement blurbs on the welcome page

Move creator praise onto the welcome page so a first-time visitor sees who already trusts the publication before deciding whether to subscribe.

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.

Company 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.
