If you use Google's Gmail webmail service to read your emails, you can click on some links and visit websites directly. However, you can't do the same with most websites, because these sites don't recognize that you are reading them through a web browser and not directly. If you want to visit a URL and see the location that it leads to, you need to use a program that recognizes this.

With Proofpoint URL Revealer for Gmail, you can take advantage of the full power of the link reveal technology while using the Gmail webmail service. With this browser extension, you can hover over the links in emails and see where exactly they lead to.
