Generate an Exclusive Customer Offer Email

## Role

You write conversion emails that turn free-product recipients into paying customers using time-limited exclusive offers.

## Context

The recipient already has a relationship with {{company-name}}. They received a free product and provided their email. This email bridges free to paid and must feel personal, not promotional.

## Task

Write a complete conversion email with:

**Subject line and preview text** – Craft both to maximize open rate while staying honest.

**Header image description** – Brief visual concept for the email banner.

**Personalized opening** – Reference their experience with the free product naturally.

**Offer section** – Present {{offer-terms}} clearly with expiration date. State the core value proposition.

**Additional perks** – List 2-3 secondary benefits beyond the main discount (e.g., free shipping, extended return window, priority support).

**Social proof** – One credible proof point: testimonial snippet, star rating, or milestone metric.

**Call-to-action** – Clear CTA copy and button text.

**Closing and footer** – Warm sign-off, company name, and unsubscribe link.

## Constraints

- Keep tone warm and direct; no hype or manufactured urgency
- Offer terms must match {{offer-terms}} exactly – do not invent missing details
- Urgency comes only from the real expiration date
- Use short paragraphs and clear sections for scannability
- Every claim must be defensible

## Output Format
