It is good practice to provide contact details for queries or feedback about the policy. If your policy is intended to be a method of communicating about digital preservation with a wider audience, you may want to facilitate two way communication, and putting a point of contact on your policy is the obvious way to do this.
Note, that providing contact details can be done in many different ways, under its own heading, in the document control section or alternatively as a clear statement at the start or end of the document.
Example policy statements
Cambridge University Libraries Digital Preservation Policy (2021) - this policy very clearly provides contact details on page 1 of the policy underneath the table of contents with 'Questions about this policy?' and an email address.
Library and Archives Canada Preservation Policy Framework (2022) - under the heading 'Information' this policy includes a postal and email address for questions about the Policy Framework.
