*AKA 301Splat! because it helps you to squash 301s.
How to use this tool
Enter your name and email address, and in the ‘link list’ box enter a list of URLs you would like to check, one per line. (If you have a website we’d quite like to know about it, just out of idle curiosity, but that’s entirely optional!). Confirm that you’re not a robot (using the ‘recaptcha’ box) and click the ‘Check URLs’ button.
Your request will be queued if necessary, and when a slot becomes available all the URLs you have listed will be accessed. The results will then be sent to the email address you entered.
