Postscript provides an SMS marketing platform that enables merchants to send personalized, two-way text messages and drive purchases and support interactions. The company focuses on Shopify merchants and counts brands such as Brooklinen, Homesick, Native, Spikeball and Kopari among its customers. Since 2021 it has grown from 61 to 230 employees and from roughly 3,500 to more than 8,500 brands on Shopify, while more than doubling revenue. Customers reportedly see a 25x return on investment on average, and merchants using SMS drive roughly 40% of gross merchandise volume in some cases. Postscript highlighted high engagement days — Memorial Day saw 30–40 million texts sent versus a typical 5–10 million — as evidence of traction. The company plans to use new funding to expand sales, marketing, go-to-market and product engineering, and to work with top customers on platforms beyond Shopify while building additional personalization features. Postscript provides SMS communication tools exclusively for Shopify merchants, emphasizing opt-in, legally compliant, and spam-free messaging. The product has evolved from one-way broadcast marketing to supporting two-way interactions, including re-orders, subscription management, and collecting reviews via SMS. The company is building an API to enable deeper integrations with other Shopify plugins while remaining focused on the Shopify ecosystem. Postscript has grown rapidly: it had 14 employees and ~530 customers in December 2019 and today reports 61 employees and over 3,500 customers. It previously raised a $4.5M seed round at the end of 2019. Today it announced a $35M Series B, reflecting the company’s growth and the revenue it is seeing. Postscript provides flexible, customizable direct-to-consumer SMS marketing tools with one-click integrations, hyper-targeted triggers based on user behavior, and advanced targeting to create enriched messages. The platform emphasizes preserving SMS inbox integrity, encouraging two-way communication, and maintaining low unsubscribe rates. Postscript targets the e-commerce ecosystem and offers tailored messaging experiences for brands of all sizes. Since launching in September 2018, the company has acquired more than 500 customers, including Native, Brooklinen, StackCommerce, Frey, Oars + Alps, and Olivers. Customers report click-through rates between 7.5% and 40% and routinely see more than 26x ROI; Postscript guarantees a 4x ROI or a refund and has not issued any refunds to date. With $4.5M in newly raised seed funding, Postscript plans to expand its fully-remote workforce and onboard new clients across a variety of e-commerce verticals.
