Email alert when specified word or phrase is posted

This would be cool. Let's say you run a collectibles site where users buy, sell and trade items. You want a certain item but every time someone posts one for sale, it gets scooped up by someone. It would be great if you could subscribe to a "posting alert" for, say, "Seamaster" and when someone posted that copy, you got sent an email.

I've looked and looked but can't find this mod. It is available?

Thanks!
