Sendmux

Sendmux is an email API built for AI agents. It gives each agent a real mailbox on a verified domain or a shared address, lets it send outbound mail through your own providers, and streams inbox events live so agents can react instead of polling.

Agent mailboxes

Provision mailboxes on verified domains or a shared myagent.mx address, with clean JSON output that strips signatures and quotes.

Provider-flexible sending

Send over HTTP or SMTP using the same mailbox credential as a Bearer token and SMTP password, with Idempotency-Key retries and attachment support.

Routing controls

Bind keys to providers, delivery groups, weights, and quota windows so traffic stays inside the boundaries you set.

Real-time events

Signed webhooks for delivery and receipt events, an SSE stream for live mailbox clients, and typed change polling for resync.
