Mailagents · Agent Mail Cloud

Production-grade email infrastructure that agents can rent on demand.

Mailagents is the control plane for agent-native email: rentable inboxes, wallet-based auth, usage-based overage proofs, and reliable webhook delivery with an operator dashboard.

API Base
api.mailagents.net

All production calls target the API base domain.

Auth
SIWE

Wallet signatures + JWT, with strict production mode.

Payments
HMAC Proof

Over-limit requests use short-lived payment proofs.

Demo Inbox
5569cf201f-2@inbox.mailagents.net

Send a test email to get an auto-reply from a leased inbox.

  • Dual runtime support: Node + Cloudflare Worker.
  • Operator dashboard for live admin workflows.

Best-fit Use Cases

  • Agents that need real inboxes for signup, verification, or alerts.
  • Multi-tenant platforms requiring lease-based mailbox isolation.
