A notification for a certification campaign may include what type of message?

In the context of a certification campaign within SailPoint Identity Now, the most relevant type of message included in a notification is the Certification Email. This communication serves a specific purpose: it informs users and stakeholders about the details of the certification campaign, which includes what the certification is about, the timeline for completion, and any actions that users need to take. A Certification Email is designed to ensure that all participants are aware and understand their responsibilities during the certification process, helping to maintain compliance and security across the organization.

While other options may provide information relevant to an organization, they do not directly pertain to the specific communications sent out for a certification campaign, making the Certification Email the correct choice.
