Openmail

OpenMail is an email API built specifically for AI agents, providing each agent with a dedicated inbox provisioned via a single CLI command or API call. Unlike traditional email APIs designed for newsletter blasting, OpenMail enables two-way threaded communication, real-time delivery via webhooks or WebSocket, and automatic attachment parsing into LLM-ready text. It integrates with popular agent frameworks like LangChain, n8n, Make, and Vercel AI SDK, and is built and hosted in the EU with GDPR compliance by default.

• Instant inbox provisioning — Run openmail setup or make one API call to create a dedicated inbox with a real email address for your agent.
• Real-time inbound delivery — Choose webhooks or WebSocket to receive parsed, prioritized email data the moment it arrives, with no polling required.
• Two-way threading — Replies stay in context; customers reply in their own email client and the agent receives the full thread without any new UI.
• One inbox per agent — Each agent gets its own identity — no shared inboxes, no forwarding — supporting multiple agents per account.
• RAG-ready attachment parsing — PDFs, CSVs, images, DOCX, XLSX, and more are automatically extracted and converted to LLM-ready text.
• Custom domains — Assign custom sending domains to agents for branded, deliverable email identity.
• DKIM, SPF, DMARC — Full email authentication stack included across all plans for reliable deliverability.
• Signup automation support — Agents can handle OTP codes, verification emails, and 2FA flows end-to-end without human intervention.
• CLI and API access — Install the @openmail/cli npm package globally, run openmail setup, and start sending within minutes.
• EU-based infrastructure — All data is processed and stored in the EU, with GDPR as a legal guarantee, not just a checkbox.
