An RFM matrix sorts every customer by how recently they bought and how often. By the Numbers does the math, shows the revenue each group holds, and lets you set the cutoffs. The result is seven groups you can act on, not a spreadsheet of raw rows.
Stop blanket-discounting your VIPs. The matrix tells you who would have bought anyway, who needs a nudge, and who is gone unless you act fast. Match the offer to the group.
Sync the At risk group to a Klaviyo flow with a 15% off code that expires in 72 hours. You win back customers you already paid to acquire.
The Best group holds your top customers. Send them an early-access drop, a hand-written thank-you, or a referral incentive. Don’t waste a discount.
Filter Best and Loyal customers who bought in that category. Their group size and AOV give you a floor estimate for first-week sell-through.
The RFM matrix sorts customers by how recently and how often they buy. These are the default cutoffs; you can change them and rename any group.

One break-up email beats a four-week flow. Stop spending on them after.
The same dataset answers five business questions. Teams that run all five get more value from every customer they’ve already paid to acquire.
Match the channel and the offer to the group. Best customers get an early-access invite; At risk customers get a 20% off code with a deadline. The same budget goes further.
Use each group’s purchase history to choose the next product to recommend. With customers sorted by group, cross-sell flows are simple to plan.
Plan restocks around what each group buys. Best and Loyal customers drive your core SKU plan; Promising customers signal which new SKUs to expand.
The matrix shows customers sliding from Loyal toward At risk before they go dormant. Catch them while a single email still works.
Move customers from Promising to Loyal to Best with lifecycle flows. Once your groups are defined, you can point a flow at each one.
A manual RFM analysis is a seven-step job: export orders, group by recency, group by frequency, calculate monetary value, compute lifetime value, average each group, then rebuild the cells. The snapshot goes stale as new orders arrive, so the work repeats.
Hiring a dedicated data analyst to keep it fresh runs $80,000 to $120,000 a year. A one-off agency engagement to build it once costs $5K to $15K. By the Numbers ships the RFM matrix as part of the platform from $19/mo, rescores it regularly, and syncs any group to Klaviyo, Mailchimp, Meta, and more. Shopify includes a built-in RFM report that scores customers 1 to 5 and sorts them into 11 groups. By the Numbers lets you set the cutoffs and names, and sends each group to your email and ad platforms.
What manual RFM costs you
“The Loyalty, Segment, and Cohort sections are very comprehensive. The team shipped enhancements incredibly fast and support is top-tier.”

“The customer loyalty report helped me bring back customers that were about to defect. The information already paid for the app for years.”
Install on Shopify and sync your first win-back group to Klaviyo or another platform.
