Send Email

Send emails via the Python script. SMTP settings are injected by OpenClaw at runtime when the script runs (from ~/.openclaw/openclaw.json → skills.entries.send-email.env). Do not read any config file (e.g. ~/.openclaw/openclaw.json or workspace/openclaw.json) — that would expose credentials in tool output. Just run the script; env is injected automatically. Do not use ~/.msmtprc.

Configuration

Configure in ~/.openclaw/openclaw.json:

"skills": {
  "entries": {
    "send-email": {
      "enabled": true,
      "env": {
        "EMAIL_SMTP_SERVER": "smtp.163.com",
        "EMAIL_SMTP_PORT": "465",
        "EMAIL_SENDER": "your-email@163.com",
        "EMAIL_SMTP_PASSWORD": "YOUR_AUTH_CODE"
      }
    }
  }
}

Variable	Description
EMAIL_SMTP_SERVER	SMTP server, e.g. smtp.163.com, smtp.gmail.com
EMAIL_SMTP_PORT	Port, 465 (SSL) or 587 (TLS)
EMAIL_SENDER	Sender email address
EMAIL_SMTP_PASSWORD	Authorization code / app password (163/QQ: auth code; Gmail: App Password)

Agent instructions

1. Credentials: Never read config files. OpenClaw injects skills.entries.send-email.env when the script runs — do not use the read tool on ~/.openclaw/openclaw.json or workspace/openclaw.json (exposes secrets). If the skill is enabled, assume env is configured; do not ask the user for passwords. Do not use ~/.msmtprc.
2. Send mail: Run the script under workspace (do not use the path under node_modules):

   python3 ~/.openclaw/workspace/skills/send-email/send_email.py "recipient" "Subject" "Body"
   

3. Attachment: python3 ~/.openclaw/workspace/skills/send-email/send_email.py "recipient" "Subject" "Body" "/path/to/file.pdf"

Usage examples

python3 ~/.openclaw/workspace/skills/send-email/send_email.py 'recipient@example.com' 'Subject' 'Body text'
python3 ~/.openclaw/workspace/skills/send-email/send_email.py 'recipient@example.com' 'Subject' 'Body' '/path/to/file.pdf'

SMTP reference

• 163: smtp.163.com:465, requires authorization code (not login password)
• Gmail: smtp.gmail.com:587, requires App Password
• QQ: smtp.qq.com:465, requires authorization code

Troubleshooting

• Authentication failed: Check that EMAIL_SMTP_PASSWORD is the authorization code or App Password.
• Connection failed: Check EMAIL_SMTP_SERVER and EMAIL_SMTP_PORT.
