By the Numbers
A sixteen-cell RFM matrix and hourly audience syncing, from nineteen dollars a month
By the Numbers is a Shopify analytics and segmentation app that scores every customer into a sixteen-cell RFM loyalty matrix, builds custom audiences from more than seventy-five filters across orders, products, lifetime value, and acquisition channel, pushes those segments to Klaviyo, Meta, Google Ads, and TikTok with hourly refresh, and wraps the whole thing in thirty-eight pre-built reports and a weekly AI briefing, starting at $19 a month.
Overview
The cheapest credible customer segmentation on Shopify is also one of the most complete, which is an unusual sentence to write. By the Numbers starts at $19 a month and ships a full RFM loyalty matrix, a filter builder with more than seventy-five conditions, hourly audience syncing into the major ad and email platforms, and a reporting layer covering orders, products, cohorts, and ad performance. Most of its competitors charge five to ten times that for a narrower product.
The segmentation model is the sixteen-cell RFM matrix, which is the version of RFM that actually helps rather than the three-bucket simplification most tools ship. Customers land in named cells such as champions, at risk, and hibernating, and the cells are populated continuously rather than recalculated when somebody opens a report. That structure is what makes the same segment mean the same thing in March and in September.
Hourly sync is the specification that separates this from cheaper reporting apps. Audiences refresh into Klaviyo, Meta, Google Ads, and TikTok every hour with no CSV in the loop, which is fast enough that a segment built around a behavioral trigger stays honest. Competitors on daily refresh are fine for win-back campaigns and noticeably worse for anything reacting to a purchase or a lapse in the last day.
The reporting breadth is genuinely wide for the price: thirty-eight pre-built reports, predictive sales forecasting, a server-side conversion pixel, and an automated Monday briefing summarizing what moved. That breadth is also the main thing to be careful about, because it means the product overlaps with profit analytics tools and with parts of what a store's existing dashboards already do, and the overlap is worth mapping before adding another subscription.
The vendor is the least documented thing about it. The app is operated by Unsupervised LLC and has around two thousand Shopify installs with a 5.0 rating across seventy-plus reviews, which is a strong adoption record, but there is essentially no public corporate information: no named founders, no funding history, no disclosed team. For a $19 app that is a normal state of affairs, and it is still worth knowing before a store builds its audience infrastructure on top of it.
Best for
Cost-conscious Shopify stores that want a real RFM segmentation model with fast audience syncing into email and paid social, plus broad reporting, without paying analytics-suite prices or waiting a day for audiences to refresh.
Not the right fit for
- Stores on platforms other than Shopify, since it installs as a Shopify app and reads Shopify data.
- Businesses that need a documented public API for pushing segments into custom systems, which is not what this product is built for.
- Teams that want to describe a segment in plain English rather than assemble conditions, which is the specific thing Tresl does better.
- Buyers who require a well-documented vendor with named leadership and a disclosed corporate history before adopting a tool.
- Stores with no repeat-purchase history, where RFM has nothing meaningful to separate and the matrix will simply describe first-time buyers.
How it works
- 1
You install from the Shopify App Store, with the vendor quoting about a minute to connect, and the app reads the store's order, customer, and product history.
- 2
Customers are scored and placed into a sixteen-cell RFM loyalty matrix, with named cells such as champions, at risk, and hibernating rather than raw score buckets.
- 3
You build custom segments from more than seventy-five filters spanning order behavior, products purchased, lifetime value, and acquisition channel, combining conditions as needed.
- 4
Segments sync to Klaviyo, Meta, Google Ads, and TikTok on an hourly refresh, so audiences stay close to current without any manual export.
- 5
Reporting runs alongside the segmentation: thirty-eight pre-built reports, cohort and lifetime value analysis, ad performance, and predictive sales forecasting.
- 6
An automated weekly briefing summarizes what changed, which is the feature that gets the analysis read by people who would never open the dashboard themselves.
Feature breakdown
21 features in 4 modulesRFM segmentation
The sixteen-cell matrix, updated continuously.- Sixteen-cell RFM loyalty matrix
- A full matrix rather than the three-bucket simplification most cheap tools ship, with named cells such as champions, at risk, and hibernating that stay comparable over time.
- Continuous scoring
- Customers move between cells as their behavior changes rather than when a report is generated, so a segment is a live population instead of a snapshot.
- More than seventy-five filters
- Conditions spanning orders, products, lifetime value, discount behavior, and acquisition channel, which is a wider condition set than most competitors expose at any price.
- Custom segment builder
- Filters combine into saved segments that behave like the pre-built cells, so a store's own definition of a good customer becomes a first-class object.
- Lifetime value segmentation
- Customers can be grouped by realized and projected value, which is how paid social exclusions stop treating a five-order customer like a first-time visitor.
- Acquisition channel attribution in segments
- Segments can be sliced by where the customer originally came from, which is the link between retention quality and acquisition spend.
Audience activation
Hourly sync into the tools that spend money.- Hourly refresh
- Audiences update every hour rather than daily, which is the specification that makes behaviorally triggered segments trustworthy rather than approximately right.
- Klaviyo sync
- Segments appear as Klaviyo audiences and stay current, covering the email and SMS path most Shopify stores act on first.
- Meta and TikTok audiences
- Segments push to paid social for retargeting and, just as importantly, for exclusion, so prospecting budget stops chasing existing loyalists.
- Google Ads audiences
- The same definitions feed Google, letting bidding reflect customer value rather than treating all traffic identically.
- No CSV exports
- The entire manual export and upload loop is removed, which is the difference between segmentation being a practice and being a quarterly project.
Reporting and analysis
Unusually broad for the price.- Thirty-eight pre-built reports
- Order, product, customer, and channel reporting available on install, which covers most of what a store would otherwise build by hand in a spreadsheet.
- Cohort analysis
- Customer value tracked by acquisition cohort, which is how you tell whether this year's marketing is buying better customers than last year's.
- Predictive sales forecasting
- Forward projections from order history, useful for inventory and cash planning rather than only for reporting on the past.
- Ad performance reporting
- Advertising results sit alongside customer analysis, which is what lets a segment finding turn into a budget decision in the same session.
- Weekly AI briefing
- An automated Monday summary of what moved and what needs attention. Its real function is getting the analysis in front of people who never open a dashboard.
- Server-side conversion tracking
- A first-party pixel improving the completeness of conversion data, which matters as browser-side tracking continues to degrade.
Commercial terms
The cheapest serious entry price in the category.- From $19 a month
- An order of magnitude below the analytics suites and well under the other segmentation apps, which is the product's single loudest argument.
- Fourteen-day free trial, no card required
- Long enough to see the RFM matrix populate against real history and to run one sync cycle into Klaviyo before committing.
- Shopify App Store billing
- The subscription appears on the store's Shopify invoice rather than as a separate vendor relationship to administer.
- Around two thousand installs at 5.0 stars
- A meaningful adoption base for an app at this price, with more than seventy reviews and no rating dilution so far.
Use cases
4 documentedStore owner priced out of analytics suites
Proper segmentation was quoted at several hundred dollars a month, which is impossible to justify against the store's current margin.
A full sixteen-cell RFM model with hourly syncing runs from $19, which changes segmentation from a someday project into this week's work.
Email marketer running same-day campaigns
Daily-refresh audiences meant win-back sends kept including customers who had ordered that morning.
Hourly refresh into Klaviyo keeps the audience close enough to current that behaviorally triggered campaigns can be trusted.
Paid social buyer bleeding budget on existing customers
Prospecting campaigns were serving acquisition creative to loyal repeat buyers because exclusion lists were stale.
Loyalty segments push hourly into Meta, TikTok, and Google as exclusions, so acquisition spend goes to people who have never bought.
Founder who will not open a dashboard
Reports exist and nobody reads them, so decisions get made on instinct while the data sits unopened.
The weekly briefing arrives with what actually moved, which converts a reporting tool nobody opens into a habit somebody follows.
Pricing
from $19 per monthFlat monthly subscription sold through the Shopify App Store, with tiers rising by feature and scale from a $19 entry plan.
| Plan | Price | Includes |
|---|---|---|
| Entry | From $19 per month |
The cheapest serious segmentation entry point in this category by a wide margin. |
| Higher tiers | Published on the App Store listing per month |
Confirm which tier carries the sync before subscribing, since that is the feature that removes the manual work. |
Billing notes
- The $19 entry price is the headline, but check on the current App Store listing which tier includes audience syncing, since that capability is what most buyers are actually paying for.
- Billing runs through Shopify and appears on the store's Shopify invoice.
- The fourteen-day trial requires no credit card, which is more generous than the seven days offered by some competitors in this category.
- Pricing is flat rather than metered on order volume, so it does not escalate as the store grows.
- Reporting breadth overlaps with profit analytics apps, so audit what you already pay for before adding this as a second subscription.
Value assessment: On paper this is the best capability-per-dollar in the category and it is not close: a sixteen-cell RFM matrix, seventy-five filters, hourly syncing, and thirty-eight reports for a starting price under a fifth of what Tresl charges and a third of Repeat Customer Insights. The question is not whether it is cheap, it is whether the vendor is durable, since there is no public corporate information behind an app around two thousand stores now depend on. For a store weighing $19 against not segmenting at all, that risk is easy to accept. For one about to make it the backbone of every audience in Meta and Klaviyo, keep the segment definitions documented somewhere you control.
Strengths & limitations
Strengths
- The lowest entry price in the category by a wide margin, starting at $19 a month.
- A genuine sixteen-cell RFM matrix rather than the simplified three-bucket version most cheap tools ship.
- Hourly audience refresh, faster than the daily sync most competitors offer.
- More than seventy-five segment filters spanning orders, products, lifetime value, and acquisition channel.
- Thirty-eight pre-built reports plus forecasting and ad performance, an unusually broad surface at this price.
- Server-side conversion tracking included, which matters as browser-side measurement continues to degrade.
- A weekly automated briefing that gets the analysis read by people who never open dashboards.
- Around two thousand installs at a 5.0 rating across more than seventy reviews.
Limitations
- Almost no public information about the vendor: no named founders, no funding history, no disclosed team.
- Shopify only, with no path for stores on other platforms.
- Segments are built by assembling filters rather than described in plain language, which is slower for non-analytical users.
- No documented public API, so segments cannot be pushed into custom internal systems.
- Feature breadth overlaps with profit analytics and reporting tools, so it can duplicate subscriptions a store already has.
- The tier that includes audience syncing is not the $19 entry price, so the headline figure understates the real cost for most buyers.
- Like every RFM tool, it needs real repeat-purchase history before its output means anything.
Head-to-head comparisons
5 alternativesBy the Numbers vs Segments by Tresl
from $49 per monthThe head-to-head in this category. By the Numbers is far cheaper from $19, refreshes hourly rather than daily, and ships broader reporting including ad performance and forecasting. Tresl costs $149 with sync and lets you describe a segment in a sentence instead of building conditions, and has a longer, better-documented corporate track record. Choose on who defines the segments: an analytical operator will prefer By the Numbers, a marketer who thinks in sentences will get more out of Tresl.
Full By the Numbers vs Segments by Tresl comparisonBy the Numbers vs Repeat Customer Insights
from $59 per monthBoth are Shopify RFM apps at very different prices. Repeat Customer Insights runs $59 to $249 and goes deeper on consumable and CPG repurchase cycles, cohort tracking, and prescriptive advice from a decade-old specialist. By the Numbers is cheaper, faster to sync, and broader in reporting but shallower in interpretation. Buy Repeat for the analysis, By the Numbers for the activation and the price.
Full By the Numbers vs Repeat Customer Insights comparisonBy the Numbers vs Lifetimely
from Free under 50 orders a month, then about $79Overlapping in reporting, different in purpose. Lifetimely is a profit and lifetime value product built around net margin after cost of goods and ad spend, with a free tier under fifty orders. By the Numbers is a segmentation product with reporting attached. If the open question is whether the business makes money, take Lifetimely; if it is who to talk to next, take this.
Full By the Numbers vs Lifetimely comparisonBy the Numbers vs Klaviyo
from $0 (free up to 250 profiles), then roughly $30/mo at 1,000 active profilesComplementary and cheap enough to be additive rather than a replacement. Klaviyo segments well inside its own data; By the Numbers brings order, product, and channel dimensions Klaviyo does not model as richly, then pushes the result back into Klaviyo hourly. At $19 the overlap costs little, which is a different calculation from adding a $149 tool for the same reason.
Full By the Numbers vs Klaviyo comparisonBy the Numbers vs Triple Whale
from $0 (free plan), then $219 per month (Foundation)Triple Whale is the full ecommerce analytics and attribution suite at suite prices, covering spend, creative, and profit across the business. By the Numbers covers the segmentation and reporting slice for a fraction of it. Stores running Triple Whale rarely need both; stores that found Triple Whale too expensive are exactly who this app is aimed at.
Full By the Numbers vs Triple Whale comparisonImplementation & onboarding
- Setup time
- About a minute to install and connect, with the RFM matrix populating shortly after against the store's existing history. Sync connections to Klaviyo, Meta, Google, and TikTok take a few minutes each.
- Learning curve
- Low to moderate. The pre-built matrix and reports require nothing, but getting value from the seventy-five filters means knowing what you want to isolate, which is more work than describing a segment in a sentence.
- Onboarding
- Fully self-serve through the Shopify App Store with a fourteen-day trial and no credit card required.
- Migration notes
- Segment definitions live in the app, so uninstalling stops the hourly refresh while previously synced audiences generally persist in Klaviyo, Meta, Google, and TikTok. Because there is no public API and little vendor documentation, keep a written record of important segment definitions outside the tool so they can be rebuilt elsewhere if needed.
Platform, API & security
- Platforms
- Shopify appWeb dashboard
- API
- No documented public API. Integration is through native syncs to Klaviyo, Meta, Google Ads, and TikTok rather than programmatic access, which limits its use inside custom data workflows.
- Compliance
- Operates on Shopify customer data under the store's own privacy obligationsServer-side conversion tracking makes the store responsible for the lawful basis of the data it forwards to ad platformsAudience syncing to Meta, Google, and TikTok carries the store's own consent obligations for advertising audiences
- Data residency
- Not published.
- SSO
- Authentication runs through the Shopify account.
- Security notes
- Permissions are governed by Shopify's app model and can be revoked by uninstalling. Vendor security documentation is thin, which is consistent with the general lack of public corporate disclosure and worth weighing if the store handles sensitive customer data.
Support & resources
- Channels
- Email supportIn-app supportShopify App Store support listing
- Documentation
- Product documentation plus published guides on RFM segmentation and Shopify customer analysis.
- Community
- No public forum. Around two thousand installs with a 5.0 rating across more than seventy App Store reviews.

Frequently asked questions
10 questionsWhat does By the Numbers do?
It scores a Shopify store's customers into a sixteen-cell RFM loyalty matrix, lets you build custom segments from more than seventy-five filters, and syncs those segments hourly into Klaviyo, Meta, Google Ads, and TikTok. Around that sits a reporting layer with thirty-eight pre-built reports, forecasting, ad performance, and a weekly automated briefing.
How much does it cost?
It starts at $19 a month with a fourteen-day free trial and no credit card required, which is the lowest entry price in this category by a wide margin. Check the current App Store listing for which tier carries the hourly audience syncing, since that is the capability most buyers are actually paying for.
What is the sixteen-cell RFM matrix?
It scores each customer on recency, frequency, and monetary value and places them in one of sixteen named cells such as champions, at risk, and hibernating. It matters because the three-bucket simplification many cheap tools use collapses distinctions that change what you should send. Sixteen cells is the version that supports different treatment per group.
Why does hourly syncing matter?
Because a stale audience produces wrong sends. On daily refresh, a win-back campaign can mail customers who ordered that morning, which wastes the send and corrupts the campaign's reported performance. Hourly refresh keeps behaviorally triggered segments close enough to reality to be trusted.
Does it work outside Shopify?
No. It installs as a Shopify app and reads Shopify data, so stores on WooCommerce, BigCommerce, or custom platforms cannot use it. This is a hard constraint shared with most of the segmentation tools in this category.
Does it have an API?
No documented public API. Segments reach other systems through the native Klaviyo, Meta, Google, and TikTok syncs rather than programmatically, so pushing an audience into a custom internal system is not supported. Teams that need that should look at a customer data platform instead.
How much do we know about the company?
Very little. The app is operated by Unsupervised LLC, with no named founders, no funding history, and no disclosed team. Around two thousand stores use it at a perfect rating, which is real evidence the product works, but the corporate opacity is worth knowing before making it the backbone of your audience infrastructure.
Does this replace my profit analytics tool?
Partly, and that is worth auditing rather than assuming. The reporting covers orders, products, cohorts, ad performance, and forecasting, which overlaps with what a profit analytics app does. It does not do full net-margin accounting with cost of goods and operating expenses the way a dedicated profit tool such as Lifetimely does.
Do I still need Klaviyo's segment builder?
You will still use it, and that is fine. Klaviyo segments well within its own data; this app brings order, product, and channel dimensions Klaviyo does not model as richly and pushes the results back hourly. At $19 the overlap is cheap enough to be additive rather than a decision.
How much order history do I need?
Enough for repeat purchasing to exist, which usually means a few thousand orders and a year of trading. RFM separates customers by behavior, and a store where almost everyone has ordered once will get a matrix that is technically correct and tells you nothing you did not already know.
Editorial verdict
By the Numbers is the best capability-per-dollar in customer segmentation, and the gap is large enough that price alone settles many decisions. A real sixteen-cell RFM matrix, seventy-five filters, hourly syncing into Klaviyo and the ad platforms, and a broad reporting layer starting at $19 is not a stripped-down version of what competitors charge $150 for, it is most of the same job done more cheaply and, on refresh speed, done better. Two caveats. The vendor publishes essentially nothing about itself, so keep your important segment definitions written down somewhere you control, and confirm on the App Store listing which tier actually includes the sync before assuming the entry price covers it. For a Shopify store that has been putting off segmentation on cost grounds, there is no longer an excuse at this price.
