Leading SMS marketing platform for Shopify merchants; raised $100M+; 9,000+ brands use Postscript for cart abandonment flows, post-purchase sequences, and promotional text campaigns with deep Shopify integration for real-time behavioral segmentation.

## Company Overview

Postscript is the leading SMS marketing platform built exclusively for Shopify merchants. Founded in 2018 in Scottsdale, Arizona, Postscript enables e-commerce brands to build subscriber lists, send targeted text campaigns, and automate SMS flows for cart abandonment, post-purchase sequences, and promotional announcements. The platform's deep Shopify integration allows for real-time segmentation based on purchase history, browsing behavior, and customer attributes.

The company grew rapidly during the 2020-2022 e-commerce boom, establishing itself as the category leader for Shopify SMS before expanding to support broader e-commerce platforms. Postscript raised over $100 million in funding from investors including Greylock, YC Continuity, and Accomplice. By 2024, the platform serves over 9,000 Shopify brands including major DTC names across fashion, beauty, and consumer goods, generating measurable ROAS from owned-channel text messaging.

In 2025, Postscript has expanded beyond pure SMS to offer a conversational commerce layer where customers can browse, ask questions, and complete purchases via text. The company faces intensifying competition from Klaviyo (which added SMS) and Attentive, but maintains its position through Shopify-native features unavailable on broader platforms. Revenue in 2025 is estimated at $80-100M ARR as SMS remains a high-ROI channel for DTC brands.
