Social proof copy on newsletter host beehiiv website

Beehiiv’s landing page to convert Substack users is a masterclass in credibility marketing. It doesn’t scream, it shows—with real creators, real results, and one killer proof line: “Built by the same team who created Morning Brew’s internal tools.”

Why this page hits hard

• Uses social proof via recognizable creators
• Adds authority proof with the Morning Brew connection
• Focuses on outcomes, not features
• Simple design that makes the case studies pop
• One clear CTA: “Start Writing”

Real-world versions of this move

• Shopify touts “trusted by millions of brands” on its homepage
• HubSpot highlights customers like Trello and DoorDash
• Notion drops case studies of companies switching from Google Docs
• Figma reminds designers it’s used by “teams at Microsoft and Uber”

Credibility + proof = conversion fuel. Beehiiv shows exactly how it’s done.
