Postscript review
A Shopify-focused SMS platform with automation, segmentation, and two-way commerce messaging.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Postscript is an SMS marketing platform for ecommerce brands, with a particular focus on Shopify merchants. It combines SMS and MMS campaigns with visual automation flows, behavior-based triggers, audience segmentation, subscriber acquisition, two-way messaging, analytics, and compliance safeguards. Its acquisition options include popups, checkout collection, landing pages, keywords, QR codes, and back-in-stock alerts. Shopify stores that want to connect promotional messaging with commerce activity are the clearest fit, while businesses seeking a general-purpose messaging platform may find its ecommerce orientation less relevant.
Pricing is structured around monthly spend and feature tiers. The Starter plan displays $0 per month but requires a $49 monthly minimum spend and includes campaigns and automations, unlimited segments, a dedicated toll-free number, and two opt-in keywords. Growth costs $100 per month and adds unlimited opt-in keywords plus live chat and email support. Professional costs $500 per month and adds enhanced analytics, priority live chat and email support, and API access for custom integrations. Enterprise uses custom pricing and includes an Onboarding Launch Specialist, custom product recommendations, and Data Warehouse Push. A 30-day trial provides an evaluation period, but the published plans do not provide a no-cost operating tier.
Postscript’s ecosystem fit is strongest for Shopify-centered teams. Integrations include Klaviyo, Gorgias, Recharge, Daasity, Okendo, Wonderment, and Amped, while custom integrations are supported through the Professional plan’s API access. Reporting includes messaging performance analytics, custom attribution windows, and UTM parameters, giving commerce teams ways to connect campaigns with tracked outcomes. Compliance features include opt-out detection and safeguards, and two-way messaging supports response management rather than broadcast-only communication. Choose Postscript if Shopify segmentation, acquisition tools, automated flows, and conversational SMS are central requirements. Consider an alternative if a lower-cost entry plan, published Enterprise pricing, or a platform outside the Shopify ecosystem is the priority.
