OpenMail

Email API for AI agents. Give any agent its own email address with one API call.·openmail.sh

OpenMail is an email API and infrastructure platform that gives AI agents their own dedicated email addresses. Agents can send and receive email with full threading support, get real-time inbound delivery via webhooks or WebSocket, and have attachments automatically parsed into LLM-ready text. It handles DNS, deliverability (DKIM/SPF/DMARC), and MX configuration so developers don't have to build email infrastructure themselves.

What it's for

Signup automation handling OTP codes, verification emails, and 2FAAI support inbox that receives, triages, and threads support emailsDocument processing: forwarding invoices/receipts to an agent inbox for parsing into structured JSONSales outreach agents running email campaignsOps agents processing invoices and coordinating with vendorsInternal agents replacing shared inboxes for HR or IT requests
