Looking at the documentation I would have to figure out who a VIP is. Then call an API method. The service converts the payload I send into an email. The example in the documentation looks at the last name of the user ("Zuckerberg") only. I don't think the service solves the use-case described in the title.

I admit the title is a little scoopy but it needs to grab attention. As for identifying celebrity signups, if they sign up via facebook for instance, you can quickly count their followers count for instance and alert if it's >X.
