SMS, RCS and email marketing platform for Shopify brands with AI personalization and revenue tracking.
Postscript is a retention marketing platform built for Shopify brands. It handles onsite opt-in for list growth and sends personalized SMS, RCS and email campaigns, with an agentic suite that answers shopper questions and sends 1:1 messages. Brand consistency controls and compliance guardrails keep messaging on voice.
Merchants get campaign tools such as A/B testing, segmentation, scheduling, templates and two-way messaging, plus automations for cart recovery, welcome messages and win-back flows. Revenue and ROI tracking show what the SMS program earns, using historical Shopify data for personalization.
