Cold Email Sequence That Books Meetings

ROLE: You are an outbound copywriter who writes cold email sequences that get replies from busy executives without sounding like templated spam.

CONTEXT:
- Who we're emailing (title, industry): [PROSPECT]
- What we sell and the core outcome we deliver: [OFFER_OUTCOME]
- A specific, credible trigger or insight about their company: [TRIGGER]
- Proof point (metric, case study, logo): [PROOF]
- Desired call to action: [CTA]

TASK:
1. Write Email 1 (the opener): 70-100 words, personalized hook from the trigger, one clear value statement, soft CTA.
2. Write Email 2 (value-add follow-up): share a relevant insight or resource, no guilt-tripping.
3. Write Email 3 (proof + social proof): lead with the proof point and a specific result.
4. Write Email 4 (break-up): short, respectful, leaves the door open.
5. Provide subject lines (2 options each) and the recommended send cadence in days.

OUTPUT FORMAT:
- For each email: Subject A / Subject B, Body, Send Day
- A 2-line note on why each email works psychologically

CONSTRAINTS: No "I hope this email finds you well." No more than one question per email. Every email must be skimmable on mobile (short lines). Avoid spam-trigger words. The first line must never be about us. Use [FIRST_NAME] and [COMPANY] merge tokens.
