May 31 Deadline for USPS Mail Growth 2026 Incentives

Final opportunity to register for a chance to earn 30% postage credit!

WASHINGTON, DC — May 31st , 2026, is the last day to initiate registration to participate in the 2026 Mail Growth Incentives and both the mail owner and the Postal Service must agree to the baseline on or before June 30th, 2026.

As a reminder:

• Registration for the First-Class Mail and Marketing Mail Growth Incentives is to be done in the My Products Portal, accessed through the Business Customer Gateway.
• Even if an MGI 26 registration was system-initiated based on a 2025 MGI registration, the SR Owner must still take action (agree with baseline or initiate a discussion) by May 31st. Once registration is initiated, a Service Request (SR) is opened and all communications between registrant and USPS need to occur within the Service Request. This streamlines communication, allowing easy access across the organization in a centralized location.
• Registrants should promptly review the baseline volume and associated CRIDs shown within the registration Service Request – accessible in the Related Tab.
• If the volume and CRID information match the mail owner records, the registrant should click on the “I Agree” button to complete the registration process from their side.
• If the information does not match, or the mail owner would like to discuss further, they should click the “Registration Assistance” button in the SR and select the type of discussion needed.
• Discussions can take time to investigate and review data to reach consensus among all parties.

Any registrations in discussion and not finalized by June 30th will be ineligible to participate, even if baseline discussions were initiated prior to May 31st but not agreed to by both the Postal Service and the registrant by June 30th.
