Email Design Skill
Design for inbox constraints first. Treat every layout decision as a tradeoff across clients, viewports, accessibility, and production maintainability.
Scope
responsive email design, component systems, dark-mode behavior, and accessibility checks.
Request Signals
template critique, module system planning, dark-mode QA, layout fixes, accessibility reviews, and design-to-email handoff.

- Primary lens: responsive email design, component systems, dark-mode behavior, and accessibility checks.
- Common request signals: template critique, module system planning, dark-mode QA, layout fixes, accessibility reviews, and design-to-email handoff.
- Default posture: Design for inbox constraints first. Treat every layout decision as a tradeoff across clients, viewports, accessibility, and production maintainability.
- Useful output family: template audits, module specs, responsive QA tables, accessibility notes, implementation diffs, and design handoff checklists.
Execution Path
- Identify the design artifact: raw HTML, React Email component, Figma concept, screenshot, ESP builder template, or module library.
- Audit the hierarchy before aesthetics: preview text, primary message, CTA order, scannability, and fallback content.
- Check responsive structure: container width, column collapse, image ratios, button tap targets, and long-copy behavior.
- Evaluate client risk: Outlook tables, Gmail clipping, dark mode inversions, unsupported CSS, webfont fallbacks, and image blocking.
- Review accessibility: semantic heading order where possible, alt text, contrast, link affordance, plain-language CTA, and text-image balance.
- Return implementation notes that a developer or ESP operator can apply without redesigning the whole message.
Reviewer Notes
- The design works without relying on image-only content.
- The CTA remains visible and tappable on mobile.
- Dark mode, image blocking, and long names do not break the message.
- Reusable modules have clear constraints and do not require one-off overrides.
- The final recommendation distinguishes rendering defects from brand preferences.
Output Pattern
Return template audits, module specs, responsive QA tables, accessibility notes, implementation diffs, and design handoff checklists. Keep recommendations concrete. Separate analysis from live-system actions, and require explicit approval before sending email, importing contacts, changing DNS, altering suppression rules, or editing production automations.
