Has anyone used PURLs with Unbounce?

Here is an example:

To send direct mail with a variety of personal URLs:

www.hbloom.com/alexcohen

www.hbloom.com/oligardner

The PURL would redirect to 1 Unbounce landing page.

Then, to be able to alert the sales team when Alex Cohen or Oli Gardner visited the page and if they complete some action, such as filling out a form.

Similar to www.purlem.com. It has the PURL functionality, but their landing page features leave a lot to be desired.
