What is OpenMail?

- Inbound mail over webhooks or WebSocket, no polling
- Attachments converted to plain text for models
- Sender rules by address or domain
- Hosted MCP server, CLI and REST API; works with OpenClaw, Hermes and Claude Code
OpenMail is built and hosted in the EU, under GDPR. The free plan includes 3 inboxes and 3,000 emails a month; Pro starts at $9 a month plus usage.
