2021 Promotions & Price Changes Webinar presented by Sierra Coastal PCC

 Updated PostalOne! ® Contingency Plan 

The PostalOne! Contingency Plan has been updated to reflect the merger of the PostalOne! Helpdesk with the Mailing & Shipping Solutions Center (MSSC), effective July 1, 2021.

The updated PostalOne!® Contingency Plan is now available on the PostalPro website at:

Previously, external customers would contact PostalOne! concerning Mail.dat/.xml issues, BCG resets, and technical issues within the PostalOne! program. Effective July 1, 2021, these issues should be directed to the MSSC.

Mailing and Shipping Solutions Center Contact Information during normal business hours:

Mailers experiencing an issue/outage with their system during normal business hours must contact the MSSC via phone or email to receive a ticket.

Mailers experiencing an issue/outage with their system outside of normal business hours must contact the Mailing Shipping Solution Center via email at to initiate a ticket. It is important to note that this only applies when a mailer experiences an issue with their system. Mailers do not have to contact the Mailing Shipping Solution Center during a USPS issue/outage.
*Note: The MSSC hours of operation are from Monday-Friday 7AM-7PM CST. Customers must provide either a ticket number or a copy of the email sent to to the BMEU when presenting mail, which will allow mailers to continue to present mail under the USPS PostalOne! Contingency Plan.

Waiver of January 2021 Mailer Scorecard Assessments

As a result of the extraordinary circumstances experienced during the 2020 peak mailing period, our partners in the mailing industry have seen negative impacts to their Mailer Scorecards which may have caused assessments.

Therefore,  the US Postal Service has made the decision to waive Mailer Scorecard assessments for Full-Service, Move Update, eInduction and Seamless Acceptance that resulted for January 2021.  

•    Assessments for the month of January 2021 will be closed, and prevented from logging.
•    Normal program assessments will resume for February scorecards.

We appreciate your business and look forward to a continued partnership in the future to grow our business.

Seamless Acceptance Incentive Proposal

As mentioned in the previously held 2021 Price Change webinars, the USPS is proposing an incentive for mailings that are submitted under the Seamless Acceptance program. If approved, the incentive would begin on January 24, 2021 and would be ongoing.

A rate incentive is “a discount that is not a workshare discount and is designed to increase or retain volume, improve the value of mail for mailers, or improve the operations of the Postal Service.” 39 C.F.R. § 3030.523(a)(3).

Seamless Acceptance enables the Postal Service to perform automated verifications of Seamless mailings by reconciling eDocs with barcode scans recorded on mail processing equipment and via handheld scanners, thereby improving operational efficiency when compared to the verification of mail inducted manually. The Postal Service also benefits from the enhanced visibility, which allows for more accurate postage calculation and for the Postal Service to more easily identify and correct issues with mailings.

How It Works:

This proposal provides an incentive to the Electronic Documentation (eDoc) submitters (with a qualified Seamless CRID and an Enterprise Payment System Account) for adoption of the Seamless Acceptance program.

The incentive would be based on the eDoc submitter’s Customer Registration ID (CRID).  A Seamless Mailer is defined by their CRID’s status in PostalOne! as “Seamless Acceptance.” Note: Seamless Parallel does not qualify for the discount.

The proposal is to allow Electronic Documentation (eDoc) submitters to receive a Seamless Acceptance incentive of $.001 for the pieces that qualify for Full-Service prices in the mailing, provided the eDoc submitter has an Enterprise Payment account that is used for the incentive and the mailing is paid for using an Enterprise Payment account.

•    The incentive is available to all eDoc submitters with a Seamless Acceptance CRID and an Enterprise Payment account who register in PostalOne!

•    The incentive is applied to the Enterprise Payment account that corresponds with the permit selected during registration to receive the incentive.

•    A permit that corresponds with an Enterprise Payment trust or ACH debit account must be selected to receive the incentive. Trust accounts will receive the incentive upon postage statement finalization and ACH debit accounts will receive the incentive as a daily aggregate.

•    To receive the incentive using Mail.dat: use existing Segment Record’s (.seg) “eDoc Sender CRID” field to identify the CRID of the eDoc submitter.   To receive the discount using Mail.XML: use existing OpenMailingGroupRequest > MailingGroupData > MailingFacility field to identify the CRID of the eDoc submitter.
