Hey Anthony

The solution is very simple. Add > /dev/null 2>&1 to the end of your
command(s) inside your cron.
steps to follow:
1. crontab -e
2. add "> /dev/null 2>&1" to the end of the lines you don't want to
received any notifications for. (without the quotes)
3. save

This redirects (>) the standard output (1) and standard error (2) of
the command to /dev/null (the black hole of nix)
