Why First-Class Mail Is Required

Invoices and statements must be sent via USPS First-Class Mail. This is a strict USPS requirement based on the nature of the mail content. These items cannot be sent using USPS Marketing Mail, Standard Mail, or Bulk Mail.

Important Note:

  • USPS First-Class Mail does not have alternative names.
  • Marketing Mail, formerly known as Standard Mail or Bulk Mail, is a separate class of mail and has specific restrictions regarding content.

USPS Marketing Mail Restrictions

According to Section 2.0 of the USPS Domestic Mail Manual (DMM 243), Marketing Mail:

  • Consists of mailable matter that is not required to be First-Class Mail or mailed as Periodicals, and weighs less than 16 ounces
  • May not contain bills or statements of account, except under very limited and specific exceptions outlined in section 2.5.2.
  • May not contain personal information unless it is:
    • Directly related to a product or service being advertised,
    • Used solely to support the advertising or solicitation, and
    • Included exclusively to support the advertising or solicitation

These restrictions ensure Marketing Mail is used primarily for promotional content and not for transactional or personal communications.

What This Means for Your Mailings

When using LetterStream or any other mail provider:

  • Invoices and statements must always be sent via First-Class Mail.
  • This ensures compliance with USPS standards and avoids mail delivery delays or rejections.
