The short answer
Both sides assessedBy the Numbers compared with Segments by Tresl
The 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.
Segments by Tresl compared with By the Numbers
The closest head-to-head in this category, and price is the headline. By the Numbers starts at $19 with a sixteen-cell RFM matrix, more than seventy filters, hourly syncing, and a wider reporting surface including ad performance. Tresl is $149 with the sync and answers in plain English rather than filters. Take By the Numbers if you want the cheapest live segment sync and are comfortable building conditions yourself; take Tresl if the person defining segments would rather describe them than construct them.
Choose By the Numbers if
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.
Choose Segments by Tresl if
Shopify stores that already have a few thousand orders of history, run email and paid social against their customer base, and want RFM segments defined in plain English and kept live in Klaviyo, Meta, Google, and TikTok without an analyst or a weekly CSV routine.

The plain-English builder is the point, and the pre-built segments mean an operator does not have to know RFM theory to get started. The judgement required is downstream: deciding what to send each segment, which the product does not do for you. |

Strengths and limitations
By the Numbers
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.
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.
Segments by Tresl
Strengths
- Plain-English segment building, which removes the filter-builder step where most segmentation work stalls.
- More than thirty pre-built RFM segments populated on install, so value arrives before any configuration.
- Daily automatic sync to Klaviyo, Meta, Google Ads, and TikTok, turning segments into live audiences rather than reports.
- Full order history is analyzed rather than a trailing window, so first-order and repeat behavior are scored against the real base.
Limitations
- Shopify only, so any other ecommerce platform is out of scope entirely.
- Segments the customers you already have and contributes nothing to acquisition.
- The $49 plan omits the sync, which is the feature that does the real work, making it a weaker purchase than it looks.
- A seven-day trial is short for a product whose value shows up over a full campaign cycle.
Pricing compared

- EntryFrom $19
- Higher tiersPublished on the App Store listing
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.
Segments by Tresl
Flat monthly subscription with two published tiers, priced by capability rather than by order volume, sold through the Shopify App Store.
- Analyst$49
- Analyst plus Marketing$149
At $149 with the sync running, this is one of the cheaper ways to make an ecommerce customer base addressable, and the flat pricing means a store doing thirty thousand orders a month pays the same as one doing three hundred. Compared with By the Numbers at $19, it is considerably more expensive and buys a stronger natural-language layer and a longer track record; compared with Repeat Customer Insights at $59 to $249, it trades depth of CPG-specific analysis for faster activation. The honest test is whether your email and ads teams will actually use the audiences. If the segments end up as screenshots in a weekly deck, the $49 plan is the ceiling of what this is worth to you.
Editorial verdict on each
By the Numbers
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.
Read the full By the Numbers profileSegments by Tresl
Segments by Tresl solves a specific and very common failure: the segment everybody agrees would be valuable never gets built because building it is tedious. Describing a cohort in a sentence and having it appear in Klaviyo, Meta, Google, and TikTok the next morning is a genuine change in how a small marketing team operates, and the flat $149 price makes it progressively better value as a store grows, unlike the order-metered apps it competes with. Two things decide it. If your team is happy assembling filters, By the Numbers does most of this from $19 and adds broader reporting. And the $49 tier should be treated with suspicion, because without the sync you are buying a dashboard and keeping the manual work. Shopify stores with real repeat-purchase history and an email and paid social operation that will actually use the audiences are the buyers this was built for.
