Win back the customers about to leave
At-Risk segments surface the customers whose buying cadence is slipping - before they churn. Push them straight into a Klaviyo win-back flow and keep the revenue that's already paid to acquire.
- Auto-detected At-Risk and Defected cohorts based on each customer's typical cadence
- One-click push to Klaviyo, Meta Custom Audiences, or Google Ads
- Live counts so you know the size of the prize before you send

Three Shopify problems segments solve this week
Ad spend
Your Meta CPA keeps creeping up.
Sync a high-LTV segment as a Meta Lookalike seed. Bid against people who actually look like your best customers, not your worst.
Retention
Repeat purchase rate is flat quarter-over-quarter.
Spin up a segment of customers who bought once 60+ days ago. Drop them into a win-back flow. Track the recovered revenue back to the segment.
