Attentive and Postscript are the SMS-first family — the two lifecycle-marketing platforms a US direct-to-consumer team shortlists when the buying question is "who runs our text program." Both sell the same shape: SMS-first lifecycle marketing — opt-in tooling, list growth features, campaign and journey sends — priced per active subscriber or in bundled message blocks, and scoped to Email plus SMS. This post names both vendors (our SMS marketing playbook deliberately names none), scores the archetype against an omnichannel messaging platform on the same archetype rows the lifecycle-marketing benchmark uses, keeps the reach where SMS-first wins, and prices the migration.
What Attentive and Postscript actually sell
Read the two published surfaces straight, because they are more alike than the sales positioning suggests:
- Attentive sells SMS-first lifecycle marketing to US DTC and e-commerce brands — sign-up units and list-growth tooling, a campaign and journey builder tuned for promotional texting, attribution on revenue per send, and email alongside the SMS program. Pricing runs on a per-active-subscriber or platform-fee-plus-message-bundle basis, and the published material points mid-market and enterprise buyers to a sales conversation rather than self-serve signup.
- Postscript sells the same SMS-first shape further down-market: Shopify-native opt-in collection, SMS campaigns and automations, and a self-serve signup for stores whose entire program is texting their own customer file. Pricing is bundled message blocks on a monthly plan.
Both are real products that hold their niche. The shared boundary is what a buyer has to price deliberately: the channel list stops at Email plus SMS, the consent record lives inside the vendor's list, and the bill scales with the subscriber file rather than with what you send.
The archetype rows, scored with the vendors named
These are the same vendor-free archetype rows the lifecycle-marketing benchmark and the SMS marketing playbook argue from — here scored against the SMS-first family by name, in both directions.
| Decision row | SMS-first family (Attentive / Postscript) | Omnichannel platform (Devotel Orbit) |
|---|---|---|
| SMS campaigns and journeys with opt-in tooling | ✓ | ✓ |
| Email beside SMS | ✓ | ✓ |
| Channel jurisdiction — WhatsApp, RCS, voice, video on the same consent record | ✗ Email + SMS only | ✓ |
| Consent and suppression portable, enforced in one control plane | ✗ Vendor-list scoped, re-implemented per channel | ✓ One consent store gating every channel |
| AI voice agents that read the same customer profile | ✗ | ✓ |
| Pricing | Per active subscriber or bundled message blocks, dormant subscribers billed | ✓ Per-message pay-as-you-go, published on the Pricing page |
| Self-serve signup | ◐ Postscript yes, Attentive sales-led | ✓ |
| One bill across every channel the journeys trigger | ✗ | ✓ |
Three of these rows deserve the long version, because they are where the shapes actually diverge:
- Channel jurisdiction. On the SMS-first platforms, the opt-in record, suppression list, and journey triggers each live inside Email-plus-SMS. Devotel Orbit holds one consent record per contact that gates SMS, WhatsApp, RCS, voice, and email together — the SMS marketing playbook walks through why one consent store queried at send time is the control that survives an audit, and re-implementing it per channel is the version that drifts.
- Consent and suppression portability. A STOP on the SMS-first vendor's list is a suppression inside that vendor's account. Orbit's suppression is a tenant-owned opt-out state that every channel's send gate checks, and it exports with the contact — the import pattern below ports the proof, not just the phone number, which is the same discipline the playbook applies to ported consent.
- Pricing model. Per-active-subscriber pricing bills the whole file every month, including the subscribers who never receive a message. Orbit bills per message sent, published per unit on the Pricing page — a dormant subscriber costs nothing, and the bill tracks the program's actual send volume rather than its list size.
Where SMS-first still wins
Say it plainly, because it is true: a single-channel DTC team whose execution surface is exactly SMS campaigns to its own customer list — Shopify storefront, no WhatsApp roadmap, no voice program, no contact center beside the marketing motion — is served honestly by the SMS-first shape. Postscript's Shopify-native opt-in units and Attentive's attribution reporting are built for that operator, and a team whose whole program is one channel does not pay for the other five. The carve-out holds while three conditions hold: SMS and email are the whole plan, list-size-billing matches how the finance team wants to buy, and the consent record never has to gate a second channel. The moment a WhatsApp lane, an AI voice agent on the same customer profile, or a call-center queue enters the roadmap, the one-consent-record problem stops being theoretical and the omnichannel shape stops being optional.
Migrating off the SMS-first platforms
There is no one-click Attentive or Postscript importer on Devotel Orbit today, and this comparison will not pretend otherwise. What ships is the same audience-import pattern documented for Klaviyo in the Klaviyo migration importer post: segments and contacts move through the importer's entity-by-entity flow — pick the audience kinds, run a dry-run with counts and conflicts, then execute with live progress. For an Attentive or Postscript account, the exported subscriber file (phone number, opt-in timestamp and source, suppression state) feeds that same importer as a contacts-plus-consent move. Two rules carry over verbatim from the playbook: port the consent proof, not just the number — an opt-in that lost its capture evidence is an unproven grant the first campaign inherits — and run a re-verification pass on ported consent before the first send, the same quarterly-review discipline the compliance posture review prescribes for migrated lists. The TCPA quiet-hours vs state windows post is the reference for the timing gates a marketing send must respect on day one in the new platform.

Frequently asked questions
What do Attentive and Postscript charge for?
Both price the SMS-first shape, but on different scales. Attentive sells to mid-market and enterprise DTC on a per-active-subscriber or platform-fee-plus-bundles basis, typically through a sales conversation. Postscript sells bundled message blocks on a monthly plan to Shopify stores, self-serve. In both cases the bill scales with the subscriber file, which is the structural difference from Orbit's published per-message pay-as-you-go pricing.
When is Attentive or Postscript genuinely the better answer than Orbit?
When the entire program is SMS campaigns to your own customer file — a single-channel DTC team with no WhatsApp, voice, or contact-center roadmap, and a finance team that prefers list-size-billing. That is the honest carve-out, and both vendors hold it well.
Does Orbit import Attentive or Postscript audiences directly?
There is no dedicated one-click Attentive or Postscript importer today. Audiences move through the same entity-by-entity import pattern the Klaviyo importer documents: the exported subscriber file — phone number, opt-in timestamp and source, suppression state — feeds the contacts-plus-consent import, with a dry-run before anything is written and a re-verification pass on ported consent before the first send.
Can SMS consent from an SMS-first platform carry over to WhatsApp on Orbit?
The consent record ports as what it is: a marketing opt-in for the SMS channel with its capture proof. Orbit's consent store gates per channel, so a ported SMS grant does not silently authorize WhatsApp sends — the first WhatsApp campaign needs its own opt-in, collected with the same keyword or form patterns the playbook specifies. That strictness is the audit-surviving behavior, not a migration defect.
Where does Orbit's pricing end up cheaper than per-subscriber billing?
At any subscriber count where a meaningful share of the file is dormant in a given month — a per-active-subscriber plan bills the whole list regardless of sends, while Orbit's per-message pricing bills only the messages actually attempted. The crossover depends on send frequency per subscriber, which the Pricing page lets you model against published per-unit rates rather than a sales quote.
