Attached is Customer Support Ruling (CSR), PS-324.  This CSR is being issued to assist in determining when advocacy mail is eligible for Standard Mail and when it would be required to be mailed as First-Class Mail.  The attached CSR is written on the basis of the revised DMM® language that takes effect June 1, 2005.   After June 1, the CSR will link to what will then be current postal standards. 

The Postal Service is providing the following “decision tree” as an aid to evaluate whether a mailpiece is eligible as Standard Mail or is required to be sent as First-Class Mail. 

This graphic is a flow chart to determine Standard Mail Eligibility
