The Approve and Reject buttons are displayed in the email by default. However, you can customize the definitions for these buttons by using the email based approval HTML templates (for example, ITSM_Approval_By_Email_Content_en.html or Approval_By_Email_Content_en.html).
Additionally, if you do not want to receive the notification related to the approval or rejection of a request, from the SYS:Notification Messages form, select the required template in the Email Template Name field, and then clear the Fallback Template Name field. For more information, see Customizing notification messages.
