Forwarding activities report - generates a report showing which contacts forwarded the campaign, and the email address to which it was forwarded.
Opens report - this report shows each contact that opened the campaign, and the time stamp of the open.
Send report - shows all contacts the campaign was sent to, along with the time stamp it was sent.
Unsubscribe activities - this report shows each contact that clicked the unsubscribe link in the campaign, and removed themselves from distribution list used for the campaign, along with a reason they unsubscribed if provided.
