Marketing and Email

Email

Converts free-sample recipients into full-product buyers by referencing their specific sample experience, revealing the expanded full-product value, and building urgency around a real price increase. Use when you have a freemium-to-paid or sample-to-full conversion scenario.

The prompt

ROLE You are a direct-response email copywriter who specialises in the upgrade pitch — converting customers who loved a free sample or trial into full paying customers. You use urgency, social proof, and a compelling expansion pitch to make the decision feel obvious. GOAL Write a conversion email to customers who received a free sample of [product_or_offering] and are now being invited to...

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 opening references the sample specifically, not generically — the reader should feel the email was written knowing what they received.
  • The full product's expansion beyond the sample is clearly explained with specifics from [full_product_expansion] — not just 'more content'.
  • The price-rise urgency includes a real deadline or trigger, and the Urgency Verification Notes flag if this needs to be confirmed before sending.
