What problem does it solve? Planning multi-email lifecycle flows — welcome series, nurture drips, re-engagement, post-purchase — often results in ad-hoc sends with no entry criteria, no exit conditions, and no measurement plan. This Skill turns lifecycle email into a structured system with defined triggers, pacing, one job per email, and metrics to review. ## Core Features & Use Cases - Sequence Design by Type: Predefined structures for welcome (5-7 emails), lead nurture (6-8), re-engagement (3-4), and onboarding sequences, each with timing, goals, and per-email roles. - Copy and Subject Line Guidance: Enforces one primary CTA per email, 40-60 character subject lines, word-count bands per email type, and a blocklist of generic lifecycle phrases to avoid. - Reference Library: Detailed templates for each sequence type plus a catalog of 25+ individual email types across onboarding, retention, billing, usage, win-back, and campaigns. - Use Case: A SaaS founder needs a 14-day trial onboarding sequence that drives users to their aha moment. The Skill produces a full sequence spec: trigger, exit conditions, per-email subject lines, body copy, CTAs, and a metrics plan with baselines. ## Quick Start Use the suede-emails skill to design a welcome email sequence for new trial signups with timing, subject lines, and a measurement plan.
