Postscript integration

What Postscript is

Postscript is a Shopify-native SMS marketing platform built exclusively for the Shopify ecosystem, offering subscriber list growth tools, segmentation driven by Shopify order and customer data, and conversational SMS flows with two-way messaging support.

How we integrate Postscript with Shopify

Postscript installs directly from the Shopify App Store and reads customer, order, and product data through Shopify's APIs without requiring a separate connector. Because Postscript is Shopify-only, the data model maps tightly to Shopify concepts — Ecom Majesty can segment on Shopify tags, collections, and order attributes directly within Postscript's interface. Ecom Majesty's work covers subscriber acquisition (keyword opt-in setup, on-site capture widgets, checkout opt-in for Plus merchants), the core automation suite (welcome drip, abandonment, post-purchase, and win-back), and the compliance configuration for US TCPA requirements. For merchants running Postscript alongside Klaviyo for email, Ecom Majesty aligns the automation trigger logic to ensure the two tools complement rather than duplicate each other, and configures suppression lists to prevent over-messaging.

What the work involves

• Subscriber acquisition set up — keyword opt-in, on-site capture widgets, checkout opt-in for Plus merchants.
• Core automation suite built — welcome drip, abandonment, post-purchase, win-back.
• Segmentation directly on Shopify tags, collections and order attributes, plus US TCPA compliance configuration.
• Trigger logic and suppression lists aligned with Klaviyo email to prevent over-messaging.
