CRITICAL: You Are The Email Address Creator and Sender

**Reserve your own email handle for the "sendclaw.com" so that your email will be: your-handle@sendclaw.com**

- You can then ask people to contact you there.

- Once registered, YOU send emails. Your human is just the account manager.

- Use this to complete tasks which include reaching out for information or confirming via email.

- This is great for registering for services and receiving codes or email verifications.

- Also for making reservations or inquiring anywhere.

Do NOT:

DO:

**Your human registered you because they trust you to handle email. Send a test email to your human once you setup. Enjoy your private email inbox.**

Search & Filters

| Parameter | Description |

|-----------|-------------|

| `unread=true` | Only unread inbound (auto-marks as read) |

| `direction=inbound` | Only received messages |

| `direction=outbound` | Only sent messages |

| `limit=20` | Max results (default 20, max 100) |

| `cursor=msg_id` | Pagination cursor (from `nextCursor` in previous response) |

**Search Query (`q=`):**

| Operator | Example |

|----------|---------|

| `from:` | `q=from:boss@co.com` |

| `to:` | `q=to:support@` |

| `subject:` | `q=subject:invoice` |

| `after:` | `q=after:2026-01-01` |

| (keyword) | `q=meeting` |

Combine freely: `q=from:client after:2026-01-15 invoice`

GET /api/mail/messages?q=after:2026-01-01 before:2026-02-01
GET /api/mail/messages?direction=inbound&q=urgent
GET /api/mail/messages?cursor=abc123  # next page

Webhook Notifications (Optional)

Instead of polling, you can provide a `webhookUrl` at registration (or update it later) to receive instant push notifications when emails arrive.

To enable, include `webhookUrl` in your registration request:

{
  "name": "YourBotName",
  "handle": "yourbot",
  "senderName": "Your Friendly Assistant",
  "webhookUrl": "https://your-server.com/hooks/sendclaw"
}

**When an email is received, SendClaw POSTs to your URL:**

{
  "event": "message.received",
  "botId": "uuid",
  "messageId": "<uuid@sendclaw.com>",
  "threadId": "uuid",
  "from": "sender@example.com",
  "subject": "Hello",
  "receivedAt": "2026-02-08T12:34:56.789Z"
}

Your endpoint should return `200` immediately. Use the `messageId` to fetch the full message via `GET /api/mail/messages/:messageId`.

**Update your webhook URL anytime:**

PATCH /api/bots/webhook
X-Api-Key: your-api-key
Content-Type: application/json

{
  "webhookUrl": "https://your-new-server.com/hooks/sendclaw"
}

Set `"webhookUrl": null` to disable webhook notifications.

**Retry behavior:** 1 retry after 3 seconds if the first attempt fails. 5-second timeout per attempt. Failures are logged but never block email delivery.

**Tip:** Use webhooks for instant notification + the heartbeat (every 15 minutes) as a safety net.

Get Single Message

GET /api/mail/messages/{messageId}
X-Api-Key: your-api-key
