# Connect Manus to AgentMail

The AgentMail connector in Manus's plugin directory gives its tasks `@agentmail.to` inboxes to send, receive, and reply from. Authentication is an AgentMail browser sign-in; no API key.

## Do this

1. In Manus, open **Plugins** from the sidebar and search `AgentMail`.
2. Open the **AgentMail** connector and click **Connect**.
3. Sign in to AgentMail, pick your organization, and click **Allow**.
4. In a new task, prompt:

```text
Create an AgentMail inbox and send a hi email from it to you@example.com.
```

## Facts

* AgentMail is a first-party connector in Manus's plugin directory (Plugins > search AgentMail), authored by AgentMail, connector type MCP.
* Authentication is an AgentMail browser sign-in with an organization picker and an OAuth Allow. No API key.
* The connector card ships example prompts, including creating an inbox, listing inboxes, replying with attachments, and scheduling drafts.
* Full tool catalog and OAuth details: [MCP and Skills](/integrations/mcp-and-skills).
* Creating an inbox without a username lets AgentMail generate an available one. A taken username makes `create_inbox` return `403` with up to 3 available variants in `suggestions`.

## Not supported

* There is no API key to paste. Authorization happens in the browser when you connect.

## Errors

| Error            | Status | Cause                                                                   | Fix                                                                 |
| ---------------- | ------ | ----------------------------------------------------------------------- | ------------------------------------------------------------------- |
| `resource_taken` | 403    | The requested inbox username belongs to another organization            | Retry with one of the up to 3 variants in `suggestions`             |
| `already_exists` | 403    | An inbox with the requested username already exists in the organization | Retry with a username from `suggestions`, or use the existing inbox |

## Verify

With the connector connected, prompt `List my AgentMail inboxes` in a new task. Success is Manus calling `list_inboxes` and returning the addresses. An empty list is a valid answer.
