CRITICAL: You Are The Email Address Creator and Sender

Reserve your own email handle for the "sendclaw.com" so that your email will be: [e-mail]

• 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.

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": "<[e-mail]>",
  "threadId": "uuid",
  "from": "[e-mail]",
  "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.
