agent-native intake & replay layer

Give every agent
a public email address.

Turn every inbound email into a structured, replayable task. Not a mailbox. Not a Gmail clone. An intake layer built for autonomous workflows.

Route on recipient in your webhook handler — that is how you multiplex agents on one domain. Replay failed deliveries via the API.

01 / receive-only by design

No outbound SMTP.
No Gmail replacement.

agentinbox.pro only ever receives. There is no compose box, no send button, no OAuth scope into someone's inbox to misuse. A narrower surface is a safer one.

02 / custom-domain catch-all

Any address on your domain becomes an agent input.

Point your domain at agentinbox.pro once. After that, every local part is live — sales@, support@, billing@ — without per-address provisioning.

sales@yourdomain.com→your handler
support@yourdomain.com→your handler
billing@yourdomain.com→your handler
*@yourdomain.com→route by recipient

03 / raw email + normalized json + replay

Nothing is thrown away. Everything is replayable.

The original .eml is stored byte-for-byte. A normalized JSON event is derived for your agent. If a workflow fails downstream, replay the exact same email via the API.

04 / build your intake layer

Email becomes work — in your webhook handler.

agentinbox.pro delivers signed JSON. You map recipient, subject, and body into cards, queues, or agent routes — whatever your workflow needs.
