Free E-Mail Address Lookup

What is this tool?

This tool will check to see if an E-mail address is on a known free E-mail domain, such as hotmail.com. This can help you determine whether or not an E-mail address is someones primary E-mail address. It just checks the domain, so you can either enter the E-mail address (user@example.com) or the domain (example.com), and you will get the same results.
