I assume that this program kinda works like "curl <page> | grep <string> && mailx -s 'Match' <email> <<< 'matched'". Useful when you want to periodically check if a page changed - I already used a similar thing to get concert tickets before anyone else. That being said, I feel like a browser extension might be more useful than a command line script, for this particular use case.
