Human-or-agent delegation

Hand a thread to a teammate — or to the AI agent — in one menu.

Delegation lets you assign any thread to a human teammate or to the AI Emaily agent from the same action menu, with a one-line handoff note. When you assign to the agent you also pick its authority — Manual, Copilot, or Autopilot. A system comment summarizing the handoff posts automatically, and every action is attributed.

The delegation model

Opening the assign menu on any thread gives you two destinations: a human teammate, or the AI agent. Assigning to a teammate hands them the thread to work. Assigning to the agent carries an authority level — Manual, Copilot, or Autopilot — that decides how far the agent may act on its own.

Either way you can attach a one-line handoff note, and a system comment summarizing the handoff posts on the thread. That comment is internal — the original recipient never sees it.

One menu, two delegation paths

Human-to-human and human-to-agent delegation use the same workflow intentionally. You can re-assign from a teammate to the agent (or back) without losing the comment history.

Delegating a thread

  1. 1

    Open the assign menu

    In any thread, open the “Assign” action. The menu lists your teammates and the AI agent as destinations.

  2. 2

    Pick an assignee

    Select a teammate who has access to that mailbox, or select the AI agent. If the teammate you need doesn’t have access to the mailbox, share it with them first.

  3. 3

    For the agent, choose an authority

    When you assign to the agent, pick Manual, Copilot, or Autopilot. Copilot stages a draft that waits for your approval before sending; Autopilot lets the agent act within its configured allowlist; Manual keeps the agent hands-off. Human assignees don’t take an authority — they simply own the thread.

  4. 4

    Add a handoff note

    Optionally type a one-line note: “Chase for the signed contract” or “Do not offer a refund.” The note is included in the handoff summary the assignee (or agent) sees.

  5. 5

    Confirm

    Assign the thread. A system comment summarizing the handoff posts, the assignment status updates, and — if you assigned the agent under Copilot — it can auto-draft a reply staged for your review.

Assignment statuses

Every assigned thread moves through a four-state lifecycle: open → working → needs_review → done. Teammates and the agent advance the status as work progresses, and the status is always visible on the thread and in the team inbox list.

Internal comments and @mentions

Any team member can post an internal comment on a thread at any time. Internal comments are private to the team — they are never emailed to the customer or included in any reply.

Use @mentions to notify a specific teammate; the mentioned person gets an in-app notification. The agent reads internal comments as context when it works the thread.

Internal comments never reach the customer

Comments and @mentions are private to your team — they are never emailed to the customer and are stripped from any outgoing reply. There is no way to accidentally send an internal comment to the outside world, so you can coordinate freely on the thread.

Agent authority — Manual, Copilot, Autopilot

When you assign a thread to the agent you pick its authority. Under Copilot, assigning can auto-draft a reply that is staged for your review — nothing sends until you approve or edit it in the approval panel. Manual keeps the agent hands-off: it helps on request but doesn’t act on the thread on its own.

Autopilot lets the agent act within its configured action allowlist without per-send approval. Autopilot is gated and requires explicit opt-in per mailbox. Whichever authority you choose, the handoff posts a system comment summarizing what happened.

Who can reply and who can administer

Members (collaborators) can assign threads, post comments, and reply via Copilot. Viewers can read and comment only — they cannot reply to external email. Sharing or unsharing mailboxes, setting roles, and managing per-member access are owner/admin-only actions.
