broken-url-notifier

Thank you for this creating this plugin. I use it to make sure users of my website post links correctly, it can also show bad bots trying to scan my website.

Simple, virtually no setup, and doesn't force you to use an icon (which I really appreciate, because it's far too easy to fall into the quicksand of plugin setup and scaffolding). Email comes in immediately that a broken link has occurred, and it doesn't interrupt the 404 page I modified in my theme. Basically, perfect.
