I would suggest hiring a talented programmer (or team) to build such tools.
The best tools aren't available publicly. Marketeers create them on their own / get them created for their own use.
That's an interesting finding you've got there.
I've read in other places that Google is starting to use their own tools like FeedBurner and Google Analytics for this same purpose.
Good find!
