About Postscript

Postscript is an SMS marketing platform built for Shopify merchants, enabling e-commerce brands to grow subscriber lists and drive revenue through targeted, personalised text message campaigns.

Editorial Assessment

Postscript is an SMS marketing platform built exclusively for Shopify merchants — offering subscriber list growth, automated SMS flows, campaigns, two-way messaging, and revenue attribution designed around Shopify's native event data and customer records. Founded in 2018 by Alex Beller, Adam Turner, and Colin Turner in San Francisco, Postscript launched as the Shopify-native SMS alternative at a time when the category was dominated by general SMS platforms without deep ecommerce integrations. The platform's Shopify integration depth allows one-click connection, automatic subscriber import from existing customer records, and real-time event triggers from Shopify checkout events, cart actions, and customer behavior. Postscript Automations cover cart abandonment, welcome series, post-purchase, browse abandonment, and loyalty programs — all triggered by native Shopify events without webhook configuration. The platform's Revenue Attribution model tracks SMS-driven revenue by matching click-through and purchase events to each message. Postscript Sales uses SMS to support direct-to-consumer sales conversations with AI assistance. Pricing is pay-as-you-go (no monthly platform fee) or with a monthly subscription plan: Growth ($100/month base); Professional ($500/month base); Enterprise (custom). Messages are priced per send (~$0.01/SMS). Postscript competes directly with Attentive (enterprise-positioned) and Klaviyo SMS for the Shopify store market.

Strengths
  • Built exclusively for Shopify — native event integration without webhook configuration
  • Pay-as-you-go pricing option makes it accessible without large monthly commitment
  • Postscript Sales for direct SMS-based sales conversations with AI assistance
  • Pre-built Shopify automation flows: cart abandonment, post-purchase, browse abandonment
  • Revenue attribution matching SMS clicks to Shopify purchases for clear ROI reporting
  • Simple, Shopify-first onboarding — most stores live in under 30 minutes
  • Compliance tools for TCPA-compliant opt-in and list management
Limitations
  • Shopify-only — brands on WooCommerce, BigCommerce, or custom stacks are not supported
  • Less brand recognition than Attentive at enterprise tier — smaller customer success team
  • Email marketing not included — SMS-only platform requiring separate email tool
  • Conversation features (Postscript Sales) require additional setup and training
  • International SMS support less extensive than enterprise alternatives

Best For
