What problem does it solve? Designing multi-email automated flows requires balancing timing, copy structure, segmentation, and conversion goals, and most teams lack a repeatable framework for building welcome, nurture, re-engagement, and onboarding sequences. ## Core Features & Use Cases - Sequence Design: Build welcome, lead nurture, re-engagement, onboarding, and post-purchase sequences with defined length, timing, and exit conditions. - Email Copy Framework: Apply hook-context-value-CTA structure, subject line patterns, preview text rules, and CTA guidelines for every email. - Lifecycle Email Reference: Audit or implement onboarding, retention, billing, usage, win-back, and campaign emails using a comprehensive type checklist. - Use Case: A SaaS team needs a 14-day trial onboarding sequence that drives users to their aha moment; the skill outputs a per-email plan with subjects, timing, copy, and CTAs. ## Quick Start Ask the assistant to create a welcome email sequence for new trial signups with a 14-day conversion goal.
