About Postmark
Postmark ships Skills for AI coding agents and an async-first Python SDK — leaning into the agent-built-app era.
Postmark released two coordinated developer-platform moves. First, an open-source set of 'Postmark Skills' designed to teach AI coding agents — Claude Code, Cursor, GitHub Copilot, OpenAI Codex, Gemini CLI — accurate Postmark API context, covering send/batch/bulk, inbound, templates, webhooks, and message streams. Second, an official Python SDK built async-first, with split ServerClient and AccountClient surfaces and Python 3.10+ support. Around these, the team is highlighting bulk email send capabilities and routine maintenance (Axios 1.13.5 in the JS SDK).
