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

About this skill
What does the email-creative-builder skill do?

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

How do I install it?

Run `npx skills add aaron-he-zhu/aaron-marketing-skills --skill email-creative-builder --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.

Where does this skill come from?

From aaron-he-zhu/aaron-marketing-skills, a repository with 2,508 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.

Is a popular skill a good skill?

Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
