Gmail is implementing a new unsubscribe button and offers a suggestion for senders that will allow a simple unsubscribe button to show in hopes that they will click that rather than hit junk/spam. Their recommendation is below. I'm wondering how we can do this with OemPro. Is there any way? I currently have version 4.0 and because of some customization, $ spent, I really don't want to upgrade to have to re-implement everything I did.

For those of you senders who are interested in this feature, the most basic requirements are including a standard "List-Unsubscribe" header in your email with a "mailto" URL and, of course, honoring requests from users wishing to unsubscribe. You'll also need to follow good sending practices, which in a nutshell means not sending unwanted email (see our bulk sending guidelines for more information).
