E-0.3 Validating Telemarketing and Internet Requests If a telephone or Internet request is not substantiated by a business reply mail system or similar technique of obtaining the requester’s signature, there are three alternative methods of validating such a request: The Postal Service sends a card to names selected by a Postal Service reviewer soliciting a response confirming that the recipient has requested and is receiving the publication. A publisher’s letter approved by the Pricing and Classification Service Center. The publisher sends a letter, preapproved by the Postal Service, to selected names with a reply card or letter to be returned to the Postal Service reviewer. See Appendix H for a sample of this letter. Authorized audit bureau reviews. The publisher can present a review from a certified audit bureau.
