RFM segmentation scores each customer on three dimensions: Recency (how recently they bought), Frequency (how often) and Monetary (how much for). The scores divide the base into segments like VIPs, loyal, dormant and lost.

The three dimensions
Recency is the strongest predictor of the next purchase: a customer who bought recently is far more likely to buy again than one who's been away a while. Frequency captures loyalty: how often the customer returns. Monetary weights how much the customer has spent with you. Together the three paint a rich picture no single metric gives.
Out of the three scores you form segments you can act on: new customers, loyal repeaters, high-value VIPs, customers on their way to dropping off, and already-dormant ones. Each segment deserves its own message and its own offer.
From segment to action
RFM's value lies in turning an anonymous list into actionable groups. VIPs should be nurtured, not discounted; loyal customers can be upsold; customers with falling recency need a winback before they're lost; dormant ones can be re-engaged or graduated out to protect deliverability.
In Klaviyo, RFM segments are built directly on top of purchase data and used to tailor both flows and campaigns. It's the difference between emailing everyone the same thing and hitting each customer with what's relevant right now — and that's what drives flow-based revenue.
Frequently asked questions
What does RFM stand for?
Recency (how recently the customer bought), Frequency (how often) and Monetary (how much for). The three scores combine into actionable customer segments like VIPs, loyal, dormant and lost.
Why is RFM better than emailing everyone the same thing?
Because relevance drives results. A VIP segment and a dormant segment need wildly different messages and offers. RFM turns an anonymous list into groups you can speak to directly — and that lifts both engagement and revenue.
