Testing Environment for Mailers (TEM) Guides

The Test Environment for Mailers (TEM) is a test platform designed to allow vendors to test software capabilities to submit electronic mailing information such as Full-Service (FS) mailings to the Postal Service. In this platform vendors are able to send and receive Mail.dat or Mail.XML files that will use the same field validations and business rules for mail acceptance. Prior to postage finalization, TEM will capture, log, and display error information. Vendors can make adjustments or modifications to their software code and Mail.dat or Mail.XML population, as needed, based on the test results.
