Persona: {{title}} at {{company_size}} {{vertical}} companies.
Pain we solve: {{1-line pain}}.
Proof: {{1 specific outcome with a number}}.
Soft CTA: {{e.g. "open to a 12-min look next week?"}}.

Constraints:
- Subject line: 3 to 5 words, lowercase, no clickbait. Output 3 options.
- Body: exactly 4 lines (line 1 hook, line 2 pain, line 3 proof, line 4 CTA).
- Total under 80 words.
- No "I hope this finds you well", no "I'd love to", no "quick question".
- One CTA only. No P.S.

Output: subject options, then the email body.

Generate 3 distinct hooks for the email above. Each hook should test a different angle:
1. Trigger-based (recent change at their company)
2. Peer-based (a similar company already does this)
3. Status-quo cost (what doing nothing costs them)

Each hook is 1 line under 18 words. Output as a numbered list, no commentary.
