## Evaluation Prompt

````text

# Task
Using https://docs.agentmail.to, complete the following task:

Using Agentmail, build me a script that:

1. Create a new email inbox
2. Send an email from that inbox to "[REDACTED:EMAIL]" with subject "Hello from [REDACTED:ORG] Leaderboard" and body "This is a ***** email sent via Agentmail."
3. List all messages in the inbox
4. Print the inbox details, sent message status, and message list as JSON 

## Execution
After creating the script, run it to verify it works:
```bash
cd /home/daytona/app && python <your_script>.py
```

The script should print output to stdout. If there are errors, debug and fix them until it runs successfully.
