Cold outbound

You are writing a 1-line opener for a cold email. ONE specific reference, not two.

Company: {{company_name}}
Role of recipient: {{title}}
Recent trigger (pick the strongest of these): {{recent_funding}} | {{headcount_change}} | {{tech_change}} | {{news_event}}

Output ONE sentence (max 22 words) that:
- references exactly one trigger by name
- lands a small, accurate observation about what it means for them
- does not flatter, does not say "I noticed", does not say "congrats"
- ends in a period, not a question

Output only the sentence.

Write a 4-line cold email.

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.
