Hi @jch
By default, if you track the page before the event, the event stays attached to the page (URL / title).
Then, you can also add custom dimensions to the tracked event:

Please note that your event tracking code seems wrong. You should use:
<a href="mailto:name@example.com"
title="Email Us"
onclick="_paq.push(['trackEvent', 'Contact', 'Email Link Click', 'name@example.com']);"
>Email Us</a>
