Here is a specialized web tool – how about an app that allows customers to slot your emails on the niceness scale? Nicereply (link here) is a free service (in public beta) that inserts a link into your email along with an invitation to the recipient to click the link and rate the email for professionalism and courtesy. You can create accounts for each employee, so that they can actually see how they rank amongst all employees.

Nicereply is working on an API that will permit widget creation so that you can trumpet your stellar grades to the entire Web.
