Using the eDoc is required for participation in Full-Service Intelligent Mail and streamlines operational efficiency by replacing hardcopy reports with electronic file submission. There are three ways to submit eDocs to PostalOne!®

  1. Postal Wizard: Enter Postage Statement information into the PostalOne! website. Available for Full-Service mailings under 10,000 pieces. A manual process, which only supports entry of simple mailings.
  2. Mail.dat: Mailing database created by most software that contains all the information about your mailing, excluding the addresses. Mail.dat submission is the established industry standard and the optimal solution for most mailings.
  3. Mail.XML: A mail communication tool available from advanced software packages that sends only the required mailing information directly to USPS. It's the new industry standard, which is also optimal for most mailings.

Mail.dat® and Mail.XML® users must go through TEM processing (Testing Environment for Mailers). Traditional TEM certification can take weeks, but USPS offers a streamlined process to TEM-certified software users. Work with your USPS contacts for best results.
