email-marketing

A brand product-launch email — masthead with wordmark, hero image block, headline lockup with skewed-italic accent, body copy, primary CTA, and a specifications grid. 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".

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.
