Postscript is an SMS marketing platform built for Shopify ecommerce brands, helping them grow subscriber lists, send SMS and MMS campaigns, automate text flows, and drive revenue through text messaging - a high-engagement channel for ecommerce. It focuses on making SMS a major revenue driver for direct-to-consumer brands.
The platform provides SMS list growth tools, campaign sending, automated flows (abandoned cart, welcome, post-purchase), two-way conversations, segmentation, and analytics, deeply integrated with Shopify. Its focus on SMS as a performance marketing channel, with tools to grow lists and automate revenue-driving texts, makes it popular with DTC brands.
Postscript offers three plans (restructured in 2026): Starter at 0 dollars per month with a 49 dollar monthly minimum spend (about 0.009 dollars per SMS, two keywords), Growth at 100 dollars per month (about 0.008 per SMS, unlimited keywords, live support), and Professional at 500 dollars per month (about 0.007 per SMS, API access), plus carrier pass-through fees around 0.004 per SMS.
