Informed Delivery®

The U.S. Postal Service® is enhancing the mail experience with Informed Delivery®, a free and optional notification service that gives eligible residential consumers the ability to digital preview their letter-sized mail pieces and manage their packages scheduled to arrive soon.

Informed Delivery® offers mailers the opportunity to engage users through an integrated mail and digital marketing campaign that generates additional consumer impressions, interactions, and insights.

Participating mailers can provide supplemental content, allowing users to take immediate action on a mailpiece. The United States Postal Service (USPS®) currently offers the basic campaign functionality for no additional fee. Monetization opportunities for additional features are under consideration.

Informed Delivery can help mailers increase their marketing campaign reach with a synchronized physical and digital touch point.

  • Receive multiple impressions from a single mailpiece.
  • Enhance the customer call to action with interactive digital content.
  • Connect with customers whenever, wherever — even as they travel — through a computer or mobile device.
