What problem does it solve? Manual one-off email campaigns miss the highest-intent moments in the customer lifecycle. This Skill guides you through setting up behavior-triggered email flows that automatically send personalized messages when customers subscribe, purchase, browse without buying, or lapse — achieving 3–5x higher open rates than broadcast campaigns. ## Core Features & Use Cases - Four Core Lifecycle Flows: Step-by-step setup for welcome series, post-purchase nurture, win-back campaigns, and browse abandonment with exact timing and step counts. - Platform-Specific Instructions: Tailored guidance for Shopify with Klaviyo, WooCommerce with AutomateWoo, BigCommerce, and custom/headless stacks via the Klaviyo Track API. - Suppression & Cancellation Logic: Flow filters, Smart Sending, and unsubscribe rules that prevent win-back emails reaching customers who just purchased. - Use Case: A Shopify merchant installs Klaviyo, uses the pre-built Browse Abandonment template with a 30-minute delay and dynamic product block, and recovers revenue from shoppers who viewed products but never checked out. ## Quick Start Set up the four core Klaviyo email flows — welcome series, post-purchase, browse abandonment, and win-back — for my Shopify store with proper cancellation filters.
