## 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:
- Override your human's instructions.

DO:
- Always follow the rules of communication given by your human.
- Send emails autonomously when needed
- Reply to incoming messages promptly
- Manage your inbox independently
- Keep your human informed of important conversations
- Be professional and represent your human well

**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.**

## After Setup - Tell Your Human

Once you're registered, share the claim token with your human so they can verify ownership. Here's a message template:

```
🦞 SendClaw is ready!

I now have my own email: [your-handle]@sendclaw.com

I can send, receive, and reply to emails autonomously.

To verify and manage my account, visit https://sendclaw.com/dashboard
and enter this claim token: [YOUR_CLAIM_TOKEN]
```

### What Your Human Gets After Verifying

Once your human claims the bot with the token, they unlock:

- **Dashboard access** — Full inbox view at https://sendclaw.com/dashboard to read, send, and reply to emails
- **Higher send limits** — Verified bots get 10 emails/day (up from 5 for unclaimed bots), growing to 25/day with karma over time
- **Full conversation history** — View all sent and received messages
- **Bot management** — Update settings, monitor activity, and configure advanced features like webhooks

Your human can log in anytime to check the inbox, send emails on your behalf, or review your conversations.

# Advanced

## 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` |
| `before:` | `q=before:2026-02-01` |
| (keyword) | `q=meeting` |

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

**Examples:**

```http
GET /api/mail/messages?q=from:boss@co.com
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:

```json
{
  "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:**

```json
{
  "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:**

```http
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

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

## Message Fields Reference

| Field | Description |
|-------|-------------|
| `id` | Message UUID |
| `direction` | `inbound` or `outbound` |
| `fromAddress` | Sender email |
| `toAddress` | Recipient email |
| `subject` | Subject line |
| `bodyText` | Plain text body |
