What problem does it solve? Restaurant HQ CRM teams often blast LINE messages to lapsed customers on gut feeling, with no way to verify reach beforehand or measure ROI afterward. This Skill turns churn win-back into a measurable, closed-loop campaign: define the at-risk segment from real visit data, verify LINE reachability and monthly quota before designing anything, and build the campaign with a holdout group so lift can be measured later. ## Core Features & Use Cases - Data-Driven Churn Definition: Identifies "churning but valuable" customers (worsening recency, high frequency/monetary) using RFM metrics, with thresholds derived from the actual visit-interval distribution of top customers rather than guesswork. - Pre-Send Reach Verification: Checks how many segment members are actually reachable as LINE friends and whether the month's messaging quota can cover the campaign before any design work begins. - Margin-Aware Offer Design: Selects coupon targets from high-margin menu items with proven basket co-purchase history, keeping discount rates within expected gross profit per returning customer. - Holdout-First Campaign Setup: Creates the coupon distribution scenario with a holdout group from the start, keeps it in draft until explicit owner approval, and defers ROI measurement to a later session. - Use Case: An HQ CRM manager asks "can we do something about customers who stopped coming?" The Skill segments at-risk high-value customers, confirms 180 of 240 are LINE-reachable with sufficient quota, proposes a high-margin item coupon, and presents an approval card with holdout design before enabling delivery. ## Quick Start Ask the assistant to identify customers who have stopped visiting recently and design a LINE win-back campaign with measurable ROI for your stores.
