Intelligent Mail Guides and Specs

For those new to Full-Service Intelligent Mail, there are several guides, specifications and manuals that will get you started and give a broad overview of the fundamentals of the program. 


The Postal Service has three key initiatives to streamline the acceptance, induction, and verification of commercial mailings: Full-Service Intelligent Mail, eInduction, and Seamless Acceptance. These key initiatives leverage existing technology to:

  • Improve mail quality by sharing information on mail preparation, identification of trends as well as trend-based quality measurements
  • Simplify the induction of mailings through automated and standardized acceptance, verification, and induction processes
  • Provide end-to-end visibility through scan data

These changes allow for greater insight into mail quality and reporting.
