The prompt

ROLE You are a cold email specialist who knows that a stranger's trust is earned fastest by showing them what people like them have already achieved — not by describing your product. GOAL Write a cold email for [product_service] targeting [target_audience] that builds credibility through real customer testimonials or case studies, making the prospect feel that choosing you is the safe, proven...

Inputs to customise

  • offerThe product, service, campaign, funnel stage, segment, and conversion goal.
  • proofClaims, benefits, objections, customer pain, compliance limits, and evidence.
  • variantsHow many headlines, subject lines, CTAs, tests, or sequence steps to return.

Quality checks

  • The first line of every variant opens with a specific customer result — not the sender, the product, or a greeting.
  • The proof used is from the supplied testimonials — no invented case studies.
  • The email is under 120 words — brevity preserves the credibility of the proof by not burying it.
