AI-assisted email and SMS marketing that turns audiences into customers
Drag-and-drop templates, reusable layouts, and guided steps to design and send newsletters or promotional emails without a designer.
Build automated journeys triggered by signups, purchases, birthdays, or inactivity, including welcome and abandoned-cart series.
Generate draft copy and subject lines, and use data-driven send-time suggestions to improve engagement.
Tag, segment, and filter contacts, and track engagement history in a searchable audience database.
Design, test, and govern APIs — now with AI agents in the loop
A multi-protocol client with collections, environments, variables, and reusable requests that works for local debugging and for driving automated test suites.
Generates assertions automatically, supports data-driven runs with exported datasets, and executes tests locally, in the cloud, or from CI pipelines via the Postman CLI.
Agent Mode, the Postman CLI agent skills, and a Model Context Protocol server let coding assistants build collections, write tests, and trigger API workflows from inside the editor.
A structured, queryable map of an organization's APIs, collections, and dependencies that lets agents find the right service and understand what a schema change would break.
