Postscript review and pricing

Shopify-anchored SMS for modern DTC.

By Postscript, Inc. · Founded 2018 · San Francisco, CA · private

Postscript was built Shopify-first from day one and remains the most Shopify-native SMS platform in the category. The product targets mid-market Shopify merchants who want modern conversational SMS without buying a broader email platform like Klaviyo. Postscript raised a $65M Series C in 2022 at roughly $300M valuation. The differentiation is conversational SMS plus Subscriber Lock-in features that compound list value over time, and a self-serve onboarding flow that gets brands sending within a day. For Shopify-pure merchants who do not want Klaviyo or Attentive, Postscript is usually the right call.
