Skill Files

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.

Error Handling

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.

Search & Filters

Search Query (q=):

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

Examples:

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:

{
  "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
