The best current option is to register a distribution group email as the main account holder and add our @backupradar.net email address to the group. This way we would get a copy of the individual notifications that come after the backup job runs.
So for example my current email registered for this crashplan account is firstname.lastname@example.org. I'd want to change it to email@example.com (or whatever you'd like) and then add firstname.lastname@example.org into the group along with the @backupradar.net email address. Please don't use my address in your distribution group I'm just providing an example of how it might work. :)
This will ensure that both the account holder and @backupradar.net email address get a copy of the e-mails.
Once you setup your distribution group and change the account to point to that you can set the Email notifications as shown below in the app on the computer side. This will require more effort on your part as it does need to be changed on each computer.
