OpenMail Pricing (2026)
OpenMail is free to start. OpenMail is email infrastructure for AI agents: one API call or CLI command gives each agent its own inbox and address, inbound mail arrives over a webhook or WebSocket with attachments parsed to text, and replies stay in thread, with EU data residency on every plan.
