Overview
Postscript describes itself as an AI retention marketing platform for SMS, RCS and email aimed at ecommerce brands. The company is backed by Y Combinator and Accomplice among others and has worked fully remotely since 2018.[8] It says it has “earned the trust of thousands of top merchants” but does not publish an exact customer count.[8]
Unlike suites that started in email, Postscript was built around text messaging. Every plan includes campaigns, automations and unlimited segments, a dedicated toll-free number, subscriber acquisition tools and a branded short-link subdomain. Higher tiers add unlimited opt-in keywords, enhanced analytics, API access and the removal of “Powered by Postscript” from the opt-in. Enterprise adds a dedicated customer success manager, personalised product recommendations and a Data Warehouse Push.[7] A separate Postscript AI plan bundles Brand Center, Infinity Testing and the Shopper agent.[7]
Its pricing is one of the most transparent in the ecommerce segment: a platform fee plus a per-message rate that falls as the tier rises, with average US carrier fees listed on the page. The free trial includes US$100 of credit usable in the first 30 days.[7] Email is newer to the product than SMS, so brands that want a mature email builder often pair it with a separate email tool.
