The ordering changes for SMBs
SMB here means a company with fewer than 500 employees — the cut these figures are scoped to. Every figure below is the average among buyers at companies under that size, which is not the figure published anywhere else on this channel. That is the point of the page: the corpus-wide average for an SMS platform blends this group with much larger companies, and for seven of these eight platforms the two land in different places. The scoped figure is closer to a peer benchmark if you are small — though it is still an average, and it is built on fewer ratings.
| Platform | Rated by SMBs | Kind, and how it compares |
|---|---|---|
| 8.1 | SMS specialist. The highest here, and above its all-interviews figure — on the fewest ratings of the well-sampled set. | |
| 7.7 | Email platform that also delivers SMS. The only one of the eight that lands in the same place as its all-interviews figure. | |
| 7.6 | SMS specialist, and the most-rated of them. Rates 8.0 among companies of 500 and above — its strongest showing anywhere. | |
| 7.6 | Cross-channel platform, and one of only two here that rate higher with SMBs than overall. | |
| 7 | Cross-channel platform, a shade below its all-interviews figure with this group. | |
| 7 | Email platform with SMS, concentrated in retail. Rated by too few buyers in this group for a decimal. | |
| 6.5 | Multi-product platform whose messaging sits beside reviews and loyalty. | |
| 6.3 | Enterprise suite where SMS is a module. The widest gap here between the scoped figure and the all-interviews one. | |
| not rated | Cross-channel platform, named by too few buyers in this group for a rating to mean anything. |
Two things about that ordering are worth stating plainly. Postscript has the highest observed average here, but it rests on far fewer ratings than Klaviyo's or Attentive's, so the distance between 8.1 and 7.7 is softer than two decimal places suggest. And the same ordering appears at a tighter cutoff: Postscript is still highest among companies under 200 employees.
How far each platform moves

Difference between each platform's rating among companies under 500 employees and the figure published across all interviews.
The direction is not uniform, which is the useful part. Two platforms rate higher with SMBs and five rate lower, so this is not a story about small companies being harder to please. For a fuller account of why category averages blend populations like this, see how company size shapes the stack.
The counter-current: an ordering is not a recommendation
Three cautions come with the table above. Postscript's figure rests on a fraction of the ratings behind Klaviyo's or Attentive's, so its lead is the least firm number on the page. Attentive sitting third here is not a verdict on Attentive — it is the highest-rated SMS platform among companies of 500 and above, and the two specialists publish identically across all interviews. And a rating is a satisfaction average, not a fit assessment: none of these figures tells you whether a platform handles your volume, your compliance posture or your existing stack.
What this means if you are an SMB
A scoped figure is closer to a peer benchmark than a corpus average, and it is still an average. Our read, not a rule buyers state, is that the useful move is to ask who is behind a number before letting it shorten a list — and on this page seven of eight platforms carry a different rating when the data is scoped to companies under 500 employees. Where a platform's published rating reflects substantial input from companies far larger than yours, that is worth knowing before the demo rather than after the contract.
The practical version is narrow. If you are under a few hundred employees, Postscript and Attentive carry higher SMB-scoped averages here than Salesforce Marketing Cloud does — but those ratings do not establish which platform will suit you. The questions that actually separate them are the ordinary ones: what your send volume does to the bill, whether the consent and compliance tooling fits how you collect subscribers, and how the platform sits beside the email tool you already run.

What is the best SMS platform for a small business?
Among the platforms rated by buyers at companies under 500 employees, Postscript has the highest observed average at 8.1, followed by Klaviyo at 7.7 and Attentive at 7.6. That does not establish Postscript as the best fit for every SMB: its figure rests on fewer ratings than Klaviyo's or Attentive's, and these scores measure buyer satisfaction rather than fit. The ordering is also not the one the channel publishes elsewhere — across all interviews Postscript and Attentive carry the same figure, 7.8. The same ordering appears at a tighter cutoff, with Postscript still highest among companies under 200 employees.
Is Attentive or Postscript better for a small business?
Buyers at SMBs rate Postscript higher, and buyers at larger companies rate Attentive higher — Attentive reaches 8.0 among companies of 500 employees and above, its strongest showing anywhere. Neither figure is a verdict on the product, and the two are much closer than the ordering suggests: Postscript's figure rests on far fewer ratings than Attentive's, so the gap between them is softer than two decimal places implies. What the data establishes is a different rating pattern by company size, not that one platform is universally better.
Why do SMS ratings differ between SMBs and enterprises?
Part of it is compositional: smaller and larger companies are rating different mixes of platforms. The same pattern appears in the other categories Alium has examined by company size. Beyond that the interviews do not settle the cause, and it is worth resisting a tidy one — the direction is not uniform. Braze rates slightly higher among SMBs than across all interviews, while Salesforce Marketing Cloud rates half a point lower. A published average is a blend of both groups in whatever proportion a category happens to attract.
Should an SMB trust a published software rating?
Treat it as a starting point rather than a peer benchmark. Seven of the eight SMS platforms here carry a different figure among companies under 500 employees than the one published across all interviews, and in one case the difference is half a point. Our read, not a rule buyers state, is that the useful question is who is behind the number before you let it shorten a list — and where a scoped figure exists, it is closer to a peer benchmark than a corpus average, though it is still an average.
