At the moment (v1.0.0 Beta5) is the e-mail notification default setting so that the mail is sent on every deployment. This is really not necessary if I am sitting behind the computer and watching the deployments. So I would welcome the ability to:

a) select default option for sending mail [X] Individual [_] All deployments
b) a checkbox "[X] Send result info mail" in deployment task window (selected depending on preferences)

This option is more suitable for schedulled tasks than for "life action"
