What to know about Postscript

Postscript is an SMS marketing platform built specifically for Shopify brands. It enables e-commerce stores to build SMS subscriber lists, send campaigns, and create automated flows (abandoned cart, welcome, winback) via text message. Unlike Attentive (enterprise) or Klaviyo (email-first), Postscript is focused on Shopify SMBs with per-send pricing (no large minimum commitments) and a best-in-class Shopify integration for order events and purchase data.
