Build HTML email templates that render everywhere. Use when designing email layouts, fixing Outlook rendering, implementing dark mode, adding accessibility, or choosing a templating framework.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Template Design

Build HTML email templates that render correctly across every major email client.

## When to use this skill

- Building an HTML email template from scratch
- Debugging rendering issues in Outlook, Gmail, or other clients
- Making an existing template responsive for mobile
- Adding dark mode support to email templates
- Improving email accessibility for screen readers
- Choosing between email frameworks (MJML, React Email, Maizzle)
- Optimizing image-to-text ratio for deliverability
- Template linting is failing or flagging issues

How to install

The exact contents, by fingerprint
mdr add chunkydotdev/email-skills/template-design@sha256:43d06b863f1a5c6f

The line at the top of this page pins the label git:20260330.4128460, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
