Postscript is working to hold the position of dedicated SMS and MMS infrastructure for Shopify commerce, deep on one channel rather than broad across marketing surfaces, built to sit inside a brand's existing e-commerce stack rather than replace it. Conversation about the brand touches the regulatory side of opt-in text marketing as much as the product itself, including compliance fights specific to state-level texting law. It also shows up in growth-marketing circles through people who built their playbooks while working there, citing that experience as formative years later. The read is a company known as much for its category position as for who passed through it.

Business Profile
Postscript was founded in 2018 as SMS and MMS marketing infrastructure built specifically for Shopify stores, at a time when most marketing platforms treated texting as one channel among many rather than the whole product. It has grown to roughly 277 employees and raised just over $106M to date, remaining independent. The company positions itself as deliberately narrow, built around SMS as the core channel rather than as one piece of a broader marketing suite, with a customer base concentrated among established direct-to-consumer brands that have built texting into a primary revenue channel rather than a supplementary one.
Agent Readiness
Measures how easily your agents can build on it — API, MCP, CLI, SDK, docs depth. Methodology →
Postscript has documented an MCP server, giving external agents a path to its SMS/MMS platform, alongside AI features built directly into the product: automated message optimization and an AI assistant that answers shopper questions and drives sales inside SMS conversations. The build-out so far centers more on AI-assisted marketing execution within the platform than on a public developer surface; no API or SDK documentation is on file yet.
