Leading SMS marketing platform for Shopify merchants, known for deep ecommerce integrations and conversational commerce features
Postscript is a leading SMS marketing platform purpose-built for ecommerce, with a primary focus on Shopify and Shopify Plus merchants. Founded in 2018, the company enables direct-to-consumer brands to build subscriber lists, send targeted campaigns, and automate personalized text message flows that drive measurable revenue. Its platform integrates deeply with Shopify's data layer, allowing marketers to segment audiences based on purchase history, browsing behavior, and customer attributes. Postscript has positioned itself as a premium SMS solution in the ecommerce marketing stack, competing with broader multi-channel platforms by offering deep Shopify-native functionality, compliance tooling, and a dedicated sales associate (SMS sales) feature that allows human agents to have two-way text conversations with shoppers. This conversational commerce capability differentiates Postscript from simpler broadcast SMS tools and aligns with the growing trend of high-touch customer engagement. The company has raised significant venture funding and serves thousands of Shopify merchants ranging from emerging DTC brands to large-scale retailers. Postscript operates in the rapidly growing mobile marketing and SMS commerce space, where it competes with players like Klaviyo, Attentive, and SMSBump. Its tight Shopify ecosystem focus and revenue-attribution transparency have made it a preferred choice among performance-driven ecommerce operators.
