# 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

```
Write 5 subject lines + preheader + body + CTA for [offer], destination [URL], promo mode
```

```
Draft a cold-outbound email to [persona] for [offer]; personalize on [signal]; destination [URL]
```

```
Iterate these losing subject lines: [paste]. Keep the winners, replace the rest, hold message-match to [URL].
```

## Skill Contract

**Expected output**: one content-complete email creative, 3-5 subject-line variants, a preheader, structured body copy, a single primary CTA, and a plain-text alternate, with a `creative_ref` / version / hash, a per-claim message-match note to the destination URL and any `[needs source]` flags, plus the standard handoff summary for `memory/email/email-creative-builder/`. Content-complete is not authorization to create or send through an ESP.
