From the source SKILL.md
Email is the one channel users check before they check your app. A well-crafted transactional email — clear, warm, fast-loading, and readable on any device — builds trust. A corporate, jargon-heavy, broken email erodes it. This skill handles the full stack: design, copy, deliverability.
What this skill does
Design Email is a community-contributed Claude Code skill in the conversion sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/design-email/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when asked to "build an email template", "transactional email", "welcome email", "password reset email", "email design", "React Email", "MJML", "dark mode email", "deliverability", "SPF DKIM", "email copy review", or "why is my email in spam".
