What problem does it solve? Sending identical emails to an entire subscriber list damages deliverability, spikes unsubscribe rates, and wastes revenue by treating VIP customers the same as non-buyers. This Skill guides you through building behavior-based email segments with suppression lists and list hygiene workflows. ## Core Features & Use Cases - Five Essential Segments: Set up Champions, Active Buyers, At-Risk, Engaged Non-Buyers, and an Unengaged suppression list in Klaviyo, Mailchimp, or AutomateWoo. - Behavioral Targeting: Build segments for sale shoppers, high-AOV customers, and category-specific buyers to match campaigns to audience intent. - List Hygiene & Compliance: Run quarterly sunset campaigns, suppress unengaged contacts before every send, and enforce GDPR consent rules for EU subscribers. - Use Case: Your open rates dropped below 20% and deliverability is suffering. Use this Skill to create an unengaged suppression segment, exclude it from all campaigns, and rebalance send frequency across your champion and at-risk cohorts. ## Quick Start Use the email-list-segmentation skill to set up the five core Klaviyo segments and a suppression list for my Shopify store.
