Provision real inboxes via API and give them the scale they need without running into bottlenecks introduced by Gmail.

Persistent conversations

  1. Monday

    Agent requests a quote.

  2. Tuesday

    Run ends.

  3. Thursday

    Vendor replies with a PDF.

  4. Event

    Webhook notifies your app.

  5. Agent

    New run retrieves the thread.

  6. Agent

    Agent replies.

Replies and attachments stay in one thread, ready for your agent’s next run.
