Individual skill

email-creative-builder

Use when the user asks to "write the email", "draft subject lines", or "build email creative"; produces the pre-click unit — subject-line variants + preheader, body copy, one clear CTA, and a plain-text alt — message-matched to the destination page and claims-ledger-aware. Not for pre-scoring or ranking subject-line variants (spam/truncation/render pre-score) — use subject-line-lab; not for scoring the email or computing EQS — use email-quality-auditor; not for the multi-step flow — use email-sequence-designer; not for the A/B test plan — use send-experiment-designer. 邮件文案/主题行/邮件创意

# Email Creative Builder

Writes and iterates a single email creative — subject-line variants + preheader, body copy, one clear CTA, and a plain-text alternate — each message-matched to the destination landing page and traced to approved claim wording. This is the build skill that produces the SEND **E/D** unit (the email analog of paid's ad-creative-builder). It does not score the email, run the D1 veto, or compute the EQS — that is `email-quality-auditor` — and it does not design the multi-step flow (`email-sequence-designer`) or the test (`send-experiment-designer`).

**Scope guard**: this skill builds the creative unit + message-match + claim flags only. It drafts subject-line variants for the creative but does **not** pre-score or rank them (spam-trigger flags, length/truncation, emoji-count, inbox-preview render) — that is [subject-line-lab](../subject-line-lab/SKILL.md). It scores no SEND dimension, runs no veto, and does not compute the profile-weighted EQS — [email-quality-auditor](../../deliver/email-quality-auditor/SKILL.md) owns all four vetoes (S1/S2/N1/D1) and the EQS rollup.

## Quick Start

```
