In general, email notifications currently go to the user instigating the notification, e.g. a content complete notification will go to the learner that completed the content item. Optionally, at the LMS level, a global administrator can choose to bto one or more email addresses.
Based on customer feedback, the LMS is being enhanced to allow CC and BCC settings to be applied at the system level email notification template, and the forth coming, catalogue item level email notification template level. This will allow, for example, admins to specify that notification emails should be copied to the learners approver or their line manager, or any arbitrary email address, such as the company's L&D Manager, whenever an email is generated using the notification template.
Please see the release notes for details of when this enhancement is released. If you have any questions, please contact the support team.
