What problem does it solve? Marketing teams producing CRM email campaigns often overload pieces with competing messages, multiple CTAs, product grids, and generic discount language, which erodes brand perception and conversion. This playbook gives agents and marketers a single operational standard to plan, write, design, and validate email pieces before they ship. ## Core Features & Use Cases - Editorial and design principles: Enforces one dominant idea per email, a single CTA, hero-driven storytelling, scan-friendly layouts, and limits on SKUs, modules, and hero copy length. - Automatic validation rules (R01-R12): Classifies issues as RECHAZO (rejection), CORRECCION (correction), or ALERTA (warning), covering CTA count, grid placement, hero value proposition, Swap and Ventaja Personal usage, and artificial urgency. - Email type architecture and cadence rules: Defines five email types (brand, singular offer, curated catalog, personal benefit, transactional) plus contact frequency, post-purchase cooldown, and pressure-by-customer-value guidelines. - Use Case: A copywriter drafts a Movistar promotional email featuring Swap as the hero message and three different CTAs; the playbook flags R01 (multiple CTAs, rejection) and R09 (Swap as protagonist, correction) and guides the rewrite toward a single value proposition. ## Quick Start Review my draft CRM email against the channel playbook validation rules and tell me which issues require rejection, correction, or editorial justification.
