Hoping to get some critical suggestion
Didnt use I had one done a while back and use on all my sites. Gives a fair amount of details in the email can see if it has something extra you could add to yours. The old post for it is here ErrorDocument 404 works great for my applications.
Think these are wonderful as you can repair a page, image or ban ips of wondering bots or people etc. Even add a page if it happened to be a dropped domain you just acquired
