SaaS homepage feature & benefits section cleverly adds in customer testimonials

This Mailmodo image nails the “what–what it does–what it’s done” formula perfectly. Each email type is explained with a stat that instantly builds credibility. Simple layout. Strong message. Proof baked right in.

Why It Works

• Starts with what it is: Feedback email, Registration email, Newsletter, etc.
• Follows with what it does: clear outcomes like more signups or opens.
• Ends with proof: specific percentage lifts make claims believable.
• Uses visuals to help the reader instantly “get it.”

Examples

• Slack shows “what it is” (a messaging app), “what it does” (organizes team communication), and “proof” (teams in 150+ countries use it).
• Shopify highlights its store builder, promises “sell anywhere,” then shows merchant revenue stats.
• Notion combines “all-in-one workspace” with user success stories to prove the point.
