Webform node titles - 6x
Last I checked, Webform didn't pick up a title token. 

But it is possible to send the page's url in an email by using the %server[key] token. 

For example, in the Webform tab > e-Mails subtab > E-mail template, include:

http://yourdomain.com%server[REQUEST_URI]


See this page for more info.
