email-render-builder

Use when the user asks to "build the email HTML", "make this email responsive", "fix dark-mode rendering", or "QA the email across clients"; produces the coded HTML build — a responsive table layout, dark-mode + accessibility pass, a client-render matrix, image-block fallbacks, and a plain-text parity check. Not for writing the copy — use email-creative-builder; not for scoring the email or computing EQS — use email-quality-auditor. 邮件HTML/响应式邮件/暗色模式渲染

# Email Render Builder Builds and QAs the coded HTML for a single email — a responsive table-based layout, a dark-mode + accessibility pass, a client-render matrix, image-block fallbacks with bulletproof CTAs, and a plain-text-parity check. This is the render half of SEND **Engage**: `email-creative-builder` writes the words, this skill turns them into a build that lands the same in Gmail, Outlook, Apple Mail, and on mobile. It does not write copy, and it does not score the email or run any veto — that is `email-quality-auditor`. **Scope guard**: this skill produces the HTML build + render QA + plain-text parity only. It writes no subject-line or body *copy* ([email-creative-builder](../email-creative-builder/SKILL.md) owns that), 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 ``` Build responsive HTML from this creative: [paste subject + body + CTA], destination [URL] ``` ``` QA this email HTML across Gmail, Outlook, Apple Mail, and mobile: [paste HTML]. Flag dark-mode and image-off breakage. ``` ``` Th

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

Use when the user asks to "build the email HTML", "make this email responsive", "fix dark-mode rendering", or "QA the email across clients"; produces the coded HTML build — a responsive table layout, dark-mode + accessibility pass, a client-render matrix, image-block fallbacks, and a plain-text parity check. Not for writing the copy — use email-creative-builder; not for scoring the email or computing EQS — use email-quality-auditor. 邮件HTML/响应式邮件/暗色模式渲染

How do I install it?

Run `npx skills add aaron-he-zhu/aaron-marketing-skills --skill email-render-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.
