If you send a USPS package through SendPro Online or the SendPro Online Mobile App with a label that doesn't have enough postage, the USPS requires Pitney Bowes to deduct the difference from your SendPro postage balance.

If this happens, you will receive an "Insufficient USPS Postage on Your Recent SendPro Shipment" email. The email includes the package details and the reason it did not have enough postage.

Insufficient postage can occur due to the following:

  • Incorrect Package: The wrong packaging type was used for the selected USPS class. For example, if you used Priority Flat Rate on the label, but you did not use an official Priority Flat Rate box.
  • Under Weight: The weight reported on the label was less than the actual weight of the package.
  • Duplicate: The same label was used on more than one package.


To prevent this issue, be sure to use the correct package type and weigh and measure your packages carefully. Consult the email for additional tips.
