To see all the audit logs related to a single email, click the More menu (...) and select the View Audit Logs action. 

You'll then be taken to the Audit Logs section. All the necessary drop-downs will be pre-filled. The Filter results field will also be pre-filled with the email ID. 

In the table, you'll see all the audit logs related to the particular email you selected (except for the bulk actions). 

This ID can be used later in case the user wants to search for the audit logs related just to this single email.
