Pure HTML email layout (centered single column, table fallback). Use when the brief asks for an "email", "newsletter blast", "MJML", "product launch email", or "email template". triggers: - "email" - "email template" - "newsletter" - "email blast" - "product launch email" - "mjml" - "邮件营销" - "邮件模板" od: mode: prototype platform: desktop scenario: marketing preview: type: html entry: index.html design_system: requires: true sections: [color, typography, layout, components] example_prompt: "Design a launch email for a sporty running shoe brand — masthead, hero, big headline lockup, specs grid, CTA." ---

# Email Marketing Skill

Produce a single HTML email — centered, single column, no chrome around the email body. Treat it like a marketing artifact: one big idea, one CTA.

## Workflow

1. **Read the active DESIGN.md** (injected above). Email leans on the display font more than any other surface — pick the loudest type token in the DS for the headline lockup. 2. **Pick the brand + product** from the brief. Generate a real wordmark, a real product name, and one real benefit sentence — no placeholders. 3. **Layout**, in order, all centered inside a 600–680px column on a tinted page background (so the email body looks like an email, not the page): - **Masthead** — wordmark on the left + 3 short nav links (SHOP, JOURNAL, MEMBERS) on the right. Thin underline. - **Hero block** — a 16:9 product image placeholder. Use a DS-tinted gradient or a stylized SVG silhouette of the product (shoe, bottle, headphones, whatever the brief implies). Add a tiny brand stamp on the top-left and a colorway tag on the bottom-left. - **Eyebrow** — small caps, accent color, separated by `·` characters (e.g. "NEW · MAX-CUSHION TRAINER · EMBER FLARE"). - **Headline lockup** — 2–3 line headline using the display font, all caps, extra-tight tracking. Apply a slight skew (`transform: skew(-6deg)`) on one accent word to give it a sporty parallelogram feel. - **Body** — 2–3 sentence paragraph, left-aligned, body font. - **Primary CTA** — solid pill or block button. One only. - **Specs grid** — 2×2 grid of (big number + unit + label) callouts using the display font for the numbers. - **Footer** — wordmark, address line, unsubscribe + view-in-browser links. 4. **Write** a single HTML document: - `<!doctype html>` through `</html>`, CSS inline. - Center the column with `margin: 0 auto`. Set `body { background: <tint> }` so the email-on-page metaphor reads. - No external images — use inline SVG or DS-tinted gradient blocks for the product photo. - `data-od-id` on the masthead, hero, headline, CTA, specs. 5. **Self-check**: - Email reads top to bottom in 8–10 seconds. - One CTA. Accent appears at most twice (eyebrow + CTA, or headline word). - Looks legible on a 480px window (column reflows, type drops one step).

## Output contract

Emit between `<artifact>` tags:

``` <artifact identifier="email-slug" type="text/html" title="Email — Subject Line"> <!doctype html> <html>...</html> </artifact> ```

One sentence before the artifact, nothing after.
