## What it does

The skill writes and iterates a single email creative. You get 3–5 subject-line variants, a preheader, structured body copy, one primary CTA and a plain-text alternate. Everything is anchored to the destination page: the headline, value prop and offer on the landing page must echo what the email promises.

Three modes are supported. B2C promo and lifecycle, B2B cold outbound with personalization on a named signal, and newsletter with editorial content. Before drafting, the skill reads the offer, destination URL, mode, persona and brand voice. Without a destination URL it cannot enforce message-match, so it will ask for one.

Scoring the email, the four vetoes and the EQS rollup belong to `email-quality-auditor`. Pre-scoring subjects for spam triggers and truncation is `subject-line-lab`. The multi-step flow is `email-sequence-designer`, and the A/B plan is `send-experiment-designer`. Install this one when you need a single creative; the full cycle needs the whole set.

# 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`).
