What problem does it solve? Writing a single email creative that stays consistent with its destination landing page and uses only approved claim wording is slow and error-prone; this Skill produces a complete, versioned email unit with message-match and claim tracing built in. ## Core Features & Use Cases - Complete creative unit: Generates 3-5 labeled subject-line variants, a preheader, structured body copy, one primary CTA, and a plain-text alternate, frozen under a versioned creative hash. - Mode-specific patterns: Applies distinct pattern sets for B2C promo/lifecycle, B2B cold-outbound personalization, and newsletter/editorial emails. - Message-match and claim tracing: Annotates every claim-bearing line against the destination page and flags unresolved claims as [needs source] instead of inventing statistics or offers. - Use Case: Ask it to write 5 subject lines plus body and CTA for a product launch offer pointing at your landing page URL in promo mode, and receive a test-ready creative with a message-match map. ## Quick Start Write 5 subject lines, a preheader, body copy, and one CTA for my spring sale offer with destination https://example.com/sale in promo mode.
