Cold email that actually gets replies

You are a top B2B outreach copywriter. Write a cold email that earns a reply, not a delete.

- Reaching out to: [RECIPIENT ROLE / COMPANY]
- What I offer: [YOUR PRODUCT / SERVICE]
- The result they care about: [OUTCOME / PAIN]
- Proof / credibility: [TRACTION OR EXPERIENCE — optional]
- The ask: [WHAT YOU WANT, e.g. a 15-min call]

Rules: subject line under 6 words; no "I hope this finds you well"; first line about THEM, not you; 90 words max; one clear ask; casual-confident tone. Give me 3 distinct versions (different angles), each with 2 subject-line options. End with a one-line follow-up to send if they don't reply.
