What appears in your Klaviyo account

Four ranked segments. Four predictive profile properties. Refreshed weekly. Your existing flows and campaigns trigger and branch on them natively.

Four segments

At Risk

Customers whose predicted churn probability crossed your threshold. Trigger your existing winback flow on segment entry.

Ready to Reorder

Customers approaching their individual repurchase window, scored from their own cadence, not a 30-day average.

Cross-Sell Ready

Customers whose product affinity says the next purchase is a complementary SKU. Branch your flows on it.

Top-Decile LTV

Your highest-value customers. Suppress discounts here. Use this list as the seed for any paid-channel lookalike.

Four profile properties

Written to every Klaviyo profile via the Profile API. Sample values shown for one customer profile:
