"Catch-All" URL Redirect with Tracking?

Hi, I’m curious if there’s a plugin that will accomplish this (I’ve tried half a dozen and no luck):

I run a consulting biz, and I send out direct mail to prospects. I include a personalized URL at the end of the letter, where they are sent to a page with a form.

Example: https://yoursite.com/Dave.Smith
Goes to: https://yoursite.com/form

Instead of making a separate page for every prospect I mail, any URL that is entered that doesn’t already exist on the website gets redirected to the form page.

Also, with a tracking system, either within the plugin or by email, so when someone types in
https://yoursite.com/Bob.Dole
I know if the person reacted to the letter and I can go from there!

Thanks!

PS. I’ve already tried PURLEM, it’s overkill for what I need, and it doesn’t seem to setup properly within WordPress.
