USPS Rule on First-Class, Standard-Mail Rates Leaves More Questions

For example, assume a mail piece includes a cover letter seeking donations from members. The letter lists the member’s donation from the previous year -- which is considered personal information by the USPS -- and urges the member to double the amount this year.

But what if the mailing also includes a preprinted brochure outlining the extent of international famine conditions? The purpose of this brochure is, at least in part, educational. What is the exclusive purpose of the mailing: to educate or solicit?
