Mail Sender

This skill allows the agent to send emails using a standard SMTP server (like Gmail, Outlook, etc.).

Setup

The skill uses the following environment variables for configuration:

SMTP_SERVER: (e.g., smtp.gmail.com)
SMTP_PORT: (e.g., 587)
SMTP_USER: Your email address
SMTP_PASS: Your app-specific password
FROM_EMAIL: The sender's email (optional, defaults to SMTP_USER)

Usage

To send an email, use the bundled script:

python3 skills/public/mail-sender/scripts/send.py \
  --to-email "recipient@example.com" \
  --subject "Hello from OpenClaw" \
  --body "This is a test email sent via the mail-sender skill."

Security Note

For Gmail, use an App Password instead of your primary account password. Never hardcode credentials in the script or conversation history.
