# 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.
```

```
This renders broken in Outlook and images-off — fix the layout and add fallbacks: [paste HTML]
```

## Skill Contract

**Expected output**: one email HTML build plus a render-QA report — inline-styled table layout, dark-mode-safe colors, an accessibility checklist result, a client-render matrix (Gmail/Outlook desktop+web/Apple Mail/iOS+Android), image-off fallback notes with bulletproof CTA markup, and a plain-text-parity check against the creative — with the standard handoff summary for `memory/email/email-render-builder/`.

- **Reads**: the approved email creative (subject/preheader/body/CTA and its plain-text alternate) or raw HTML to QA; the destination URL; the mode (promo/cold/newsletter); target client list and any brand color/font/logo constraints; the message-match map from [email-creative-builder](../email-creative-builder/SKILL.md) when present.
- **Writes**: a user-facing HTML build (the rendered **E/D** unit) plus the render-QA report and a reusable handoff summary.
- **Promotes**: confirmed render blockers (a client that breaks t
