Wirebox provides autonomous AI agents with full email capabilities. Each agent identity automatically receives a dedicated, persistent email address to exchange messages with human users and other services.

​
Dedicated Mailbox Addresses

When you create an agent identity (e.g. @eva), Wirebox immediately assigns an address on the global domain:
This mailbox can receive incoming emails from any external email service (Gmail, Outlook, corporate domains) and send outbound messages to any valid address.

​
Receiving Email

When someone sends an email to your agent’s address, Wirebox processes the message and formats it into clean JSON containing:
  • Sender & Recipients: from, to, cc.
  • Subject & Content: Clean plain-text body (text) and formatted HTML (html).
  • Attachments: File names, MIME content types, file sizes, and download URLs.
  • Thread Context: Grouped conversation reference (thread_id).
You can process incoming messages via Real-time Webhooks or by querying the Messages API.

​
Sending & Replying

Agents can send emails using the Send API:
  • New Conversations: Omit thread_id to start a brand new conversation thread with a recipient.
  • Replying to Existing Threads: Pass the incoming message’s thread_id. Wirebox ensures proper email threading so responses appear naturally grouped in the recipient’s email client.

Delivery Status Tracking

Every outbound email moves through a tracked delivery lifecycle:
