USPS Rate Increases for 2021 Holiday Season

Mark your calendars--USPS is implementing temporary rate increases which target key package products for the 2021 holiday season. We want to keep you informed so that you can make educated decisions for your eCommerce business. These changes will take place on October 3, 2021, and they will affect most products, weights, and zones. We’ll cover the most popular USPS shipping services including Priority Mail, First Class Package, Flat Rate, and Regional Rate.

These changes will affect a large number of eCommerce sellers and SmartShyp customers. SmartShyp will, of course, update all of our labels to reflect the new USPS pricing which will be automatically calculated. If you are a SmartShyp user, there is nothing further you need to do with your SmartShyp account.

If you offer free shipping, though, you may want to consider how you’ll take these new costs into account. A good strategy is to prepare an email blast to your customers to communicate the changes and reasoning behind the increase in shipping costs.
