There are several reasons why you may not have recieved email confirmation that your cron job completed successfully. Here are a few things to check:

1. Please confirm that you entered in your email address correctly within the control panel. If so, please also check your "Junk Folder" to make sure that the email notification was not delivered there accidentally.

2. There is the chance that your scrip may not work correctly. Check to make sure that your script has no errors and has been tested and performs as expected.

3. For you script to be readable, the file permissions should be appropriately set. Make sure that you set file permissions to at least 644.

4. Is the path to the script correct? Note that the leading slash is not required and your top-level domain directory is automatically appended to the path.
