Performance Tips

1. Use specific filters: The more specific your query, the faster the analysis
2. Limit the number of emails: Use limit or -n to analyze fewer emails for faster results
3. Use time ranges: Analyzing recent emails is faster than analyzing all emails
4. Combine filters: Multiple filters reduce the dataset size

• Default: Human-readable terminal output with visual charts
• JSON: Machine-readable format (use format=json)

Notes

• All text searches are case-insensitive
• Domain filters match partial domains (e.g., gmail.com matches mail.gmail.com)
• Keywords search both subject and body content
• The stats command reads emails but does not modify them
• Results are based on locally cached email data after initial fetch

Troubleshooting

If stats are not showing expected results:

1. Ensure your email account is properly configured: mailos info
2. Check that emails are being fetched: mailos read -n 10
3. Verify your filters are correct: Try broader filters first
4. Use the --days flag to ensure you're looking at the right time period
