Link to status page from apdex alert mail
In the body of the Apdex alert mail (or maybe every alert mail?), can you include a link to the status page of that site? This makes it easy to check the current state of a site, if the mail is already a few hours old.
Status page link has been added to downtime and performance alerts emails. It will still require login for private pages though.
Another solution for private pages: make the URL in the mail contain a (time limited?) token that will allow you to view the page anyway.
This would also mean that you would introduce a new "semi private" status page visibility level for those that work with additional e-mail alert addresses, I'm not sure whether that fits your product offering.
