Subject: Quick thought after our demo

Hi Sarah — wanted to circle back since our chat last week. I keep thinking about the workflow issue you mentioned. Worth a 15-min call to dig into it, or should I send a Loom instead? Either works — happy to make this easy.

Subject: One thing from our demo

Sarah — no pressure, but I keep coming back to the bit where you said reporting eats 4 hours of your Friday. I sketched out how we'd cut that to 20 minutes. Want me to send it, or is now not the right time? Totally fine either way.

Hi Sarah, I hope you're doing well! I wanted to follow up on our great demo last week. I'd love to know if you have any questions or would like to schedule a follow-up call to discuss next steps. Please let me know!

Claude wins this round. It referenced a specific pain point from the demo — "reporting eats 4 hours of your Friday" — instead of a generic check-in. That specificity signals the sender was actually listening, and the "totally fine either way" removes pressure without sounding desperate. ChatGPT was close but stayed vague. Gemini defaulted to corporate pleasantries. The lesson: the best follow-up emails reference a specific friction the prospect named — not the product you're selling.
