# B2B cold email copywriting
## Pipeline contract
**Stage 14 of 20.** Reads `13-personalized.csv`, `02-client-profile.yaml`. Writes `14-emails.csv` (`lead_id, segment, framework, subject, body, variant`).
- One framework per segment, 2 variants max. Write the template once per segment with merge variables; do not hand-write 500 emails.
- Run the pre-send QA checklist (section 13) and the spam-word pass (`references/spam-word-checker.md`) on every template.
- This stage DRAFTS. Nothing is uploaded or sent by the prospecting system; the human takes `14-emails.csv` to their sender.
- More frameworks: `references/copy-frameworks.md`.

A complete operating system for writing cold email that gets replies instead of spam flags. This is the exact framework we run at B2B Boosted across millions of sends. It assumes you already know that copy is only one of three levers, and it will not let you skip the other two.
## 0. The Big 3 (get the order right or nothing else matters)
Reply rate is a product of three things, in this order of impact:
1. **List (40%)** — the right person, at the right company, with the right trigger. The best copy in the world sent to the wrong list gets zero replies. Fix the list first.
2. **Offer (40%)** — a specific, believable outcome for a specific person. "We do X for Y so they get Z" beats any clever line.
