What problem does it solve? Planning multi-email automated flows is hard: teams struggle with sequence length, timing, subject lines, and copy structure, often sending unfocused emails that fail to convert. This Skill provides a complete framework for designing welcome, nurture, onboarding, re-engagement, and win-back sequences with proven patterns. ## Core Features & Use Cases - Sequence Strategy: Defines length, timing, and cadence for welcome (5-7 emails), lead nurture (6-8), re-engagement (3-4), and onboarding (5-7) sequences. - Email Type Reference: Covers onboarding, retention, billing, usage, win-back, and campaign emails with triggers, goals, and copy approaches for each. - Copy & Testing Guidelines: Provides subject line formulas, preview text rules, CTA patterns, personalization tactics, and A/B testing frameworks with benchmark metrics. - Use Case: A SaaS team needs a 14-day trial onboarding sequence. The Skill produces a per-email plan with send timing, subject lines, full copy structure, CTAs, and a metrics plan aligned to the activation goal. ## Quick Start Ask the assistant to create a welcome email sequence for new trial signups, including timing, subject lines, and CTAs for each email.
