Mailer Checklist

This little extension will:
- check your syntax
- make sure your tables have widths and try to determine if the values are correct
- highlight attributes that are best avoided
- score your performance (try to get 100 points)

If you want it to work on local files, make sure to go to Tools > Extensions (chrome://settings/extensions) and check the “Allow access to file URLs” box.
