This gives Claude a comprehensive framework for building email sequences across different lifecycle stages: welcome, nurture, re-engagement, and onboarding. You get specific timing recommendations (welcome sequences run 3-7 emails, nurture goes 5-10), subject line patterns that actually work, and detailed templates for each sequence type with suggested delays between sends. The skill emphasizes one clear purpose per email and includes strategic guidance on segmentation and CTA placement. It's thorough enough that you could hand it off and get back a complete multi-email campaign rather than just individual messages. Best for marketing automation work where you need the full customer journey mapped out, not just one-off promotional emails.
