At a glance
Attentive and Postscript both lead the dedicated SMS category but cover different audiences. Attentive scales into enterprise (multi-channel, multi-platform — Shopify, Salesforce Commerce Cloud, Magento, BigCommerce) and is the larger company; Postscript is 100% Shopify-only and skews toward DTC operators valuing Shopify-specific depth (45+ Shopify-native segmentation filters, 130M+ Onsite Opt-in Network). Attentive does not publish entry pricing on its website (qualifying call required); Postscript publishes Starter from $25/mo + per-message usage. The decisive question: do you want SMS as a dedicated Shopify specialist tool, or as part of a broader multi-platform marketing stack.

When each one wins
Winner: Postscript
Shopify-first DTC, $50K-$500K MRR
Published pricing, Shopify-specific depth (45+ filters, Shopper AI, 4x ROI guarantee), active partner program. For pure-play Shopify operators at this tier, Attentive's multi-platform infrastructure is over-engineered relative to the value delivered. Postscript wins on transparency + Shopify-native depth.
Winner: Attentive
Multi-platform operator (Shopify + Salesforce CC / Magento / BigCommerce)
Postscript does not exist outside Shopify, so multi-platform operations require Attentive by definition. The enterprise-grade abstraction layer (consistent SMS engine across stores) is the value at this scale, not Shopify-native filter depth.
Winner: Attentive
Enterprise tier ($500K+ MRR) wanting custom pricing leverage
Attentive's qualifying-call sales motion is built for enterprise contract negotiation. Postscript Enterprise exists but the bulk of Postscript's product fit is mid-market. At enterprise pricing, both are quoted custom — the decision shifts to platform breadth and enterprise-account-management depth, which is Attentive's native zone.
Our verdict
For Shopify-first DTC brands at $50K-$500K MRR — Postscript is the pragmatic specialist pick. Published pricing, 45+ Shopify-native filters, Shopper AI for conversational commerce, and a 4x ROI guarantee. Attentive is the right pick when you operate multi-platform (Shopify + Salesforce + Magento) or are at the enterprise tier where qualifying calls produce custom-quoted pricing. For pure-play Shopify under $1M ARR, Attentive's enterprise-grade infrastructure is over-engineered relative to Postscript's specialist depth. Both ship SMS competently — the differentiator is the platform breadth vs. depth tradeoff.

For the full Postscript pricing breakdown ($49 Starter minimum + platform-fee shift), see /pricing/postscript.

- KlaviyovsPostscript
Klaviyo and Postscript split cleanly by store maturity and SMS ambition. Below $50K/mo MRR — Klaviyo's bundled SMS inside the free or Email tier is the cheapest, fastest way to test SMS without onboarding a second platform. Above $50K/mo MRR with SMS as a real revenue channel — Postscript's Shopify-only specialist depth (45+ Shopify-specific segmentation filters, compliance engine, 4x ROI guarantee) pays back faster than Klaviyo SMS. The Customer Agent vs Shopper question is misleading: they solve different jobs. Postscript Shopper is pre-purchase conversational AI on SMS; Klaviyo Customer Agent is post-purchase ticket resolution priced separately as a helpdesk product. Don't pick the tool to get the AI agent — pick the tool to get the channel strategy, and the agent fits the job naturally.

For Shopify operators not yet running email at scale, Klaviyo wins by default — bundling SMS into a multi-channel CRM at $20/mo Email is cheaper than running two platforms in parallel. Above $50K/mo MRR with email already mature on a different platform and SMS becoming a real revenue channel, Attentive becomes evaluable on enterprise account-management and multi-platform infrastructure. The Klaviyo One $10K/mo threshold (mandatory above ~$10K/mo total spend, adds 20%) is the pricing inflection point — model your projected 12-month spend before committing.
