Hello,
Password Self-Service Enrollment notifications are sent only to the users affected by a Password Self-Service Policy. So, the best option would be just to exclude your service accounts from the Activity Scope of the Password Self-Service Policy. For example, if all your service accounts are located in certain OUs, you can exclude these OUs from the Activity Scope of the policy.
Another option can be to use Business Units. Business Units are virtual collections of Active Directory objects that are grouped based on certain common criteria. A Business Unit may include members of specific groups or children of certain containers/OUs, objects that match a specific LDAP filter or even specific objects that you can specify explicitly. So, you can group all your service accounts into a Business Unit and then exclude the whole Unit from the Activity Scope of the Policy. For more information on Business Units, see Business Unit Overview.
On how to include or exclude objects from the Activity Scope of a Password Self-Service Policy, see the 3rd step of the Configure Password Self-Service.
