It would be great if this plugin could add support for the Claim Plugin (https://wiki.jenkins-ci.org/display/JENKINS/Claim+plugin, 1800 installations).

I imagine two additional features shown to the user in the Project configuration, if the Claim Plugin is installed:

• A "recipient group" called "Claimer" or something so that we can select when this person gets an email.
• One or more triggers related to a failed build which is already claimed. Maybe it could be a checkbox to the existing triggers ("...and is already claimed")

The end result would be that the user can configure that for example only the owners and the claimer (i.e. not the other culprits) will be emailed when a build with a sticky Claim fails again.
