What problem does it solve? Planning multi-email automated flows is hard: teams struggle with sequence structure, timing between emails, subject lines, and knowing which lifecycle emails they are missing. This Skill provides expert frameworks, templates, and copy guidelines to design welcome, nurture, onboarding, re-engagement, retention, billing, and win-back email programs. ## Core Features & Use Cases - Sequence Design: Build welcome, lead nurture, onboarding, and re-engagement sequences with defined length, timing, goals, and per-email structure (hook, context, value, CTA). - Lifecycle Email Reference: Audit your program against a comprehensive checklist of onboarding, retention, billing, usage, win-back, and campaign email types. - Copy & Testing Guidelines: Apply subject line patterns, preview text rules, personalization, segmentation, and A/B testing practices with benchmark metrics. - Use Case: A SaaS team with a 14-day trial asks for a welcome sequence; the Skill produces a 5-7 email plan mapped to the trial timeline, each with subject line, preview text, body copy, and CTA driving users to their aha moment. ## Quick Start Ask the assistant to create a welcome email sequence for new trial users of your product, including timing, subject lines, and CTAs for each email.
