Updated USPS Postage Rates 2019: How does it affect your WooCommerce store?


When you talk shipping, logistics, or delivery in general, the United States Postal Services may come to your mind at some point in time if not early. USPS is considered a staple for both individuals and businesses in the United States of America. And rightfully so. Their estimates are really cheap (cheapest in the 0-2 Lbs package weight category), provide delivery to most locations including post offices, offer overnight delivery, and “do a lot more” so to speak. So all-in-all, USPS’s a great choice for WooCommerce store owners looking for a cheaper shipping option. Well unless of course, you want to enjoy premium benefits (i.e, accurate shipment tracking, one-day delivery, safer package handling, cheaper freight rates, etc,.) provided by carriers like UPS and FedEx. You should check out the comparison between UPS, FedEx, and USPS to really understand the differences. Anyway, if USPS is a yes, then you should be aware of the new proposed postage rates implemented on January 27, 2019. This is why in this article we are going to explore the proposed 2019 shipping rates for users buying postage online. We will also show you how the WooCommerce Multi-Carrier shipping plugin is going to help you display the rates on the Cart/Checkout page. But wait! Before you begin, you should probably understand how to use USPS along with Stamps.com and see how you can save more money. If you already know about it then you may skip the following block.

Using USPS with Stamps.com

If you’re now aware of Stamps.com, well, it’s software that integrates with your USPS account and essentially allows you to purchase postage and shipping labels online. You can save a lot of time by printing the labels on any regular printer and scheduling the pickup with USPS. With this solution coming into the picture, you can easily get your shipments in the mail without even leaving your office. How cool! The software is available in both an online version and a downloadable version for PC. Although Stamps.com is similar to many shipping software options, it is a bit less functional than the average program. Most notably, Stamps.com only allows you to purchase postage from the USPS, while other shipping solutions give you a wider range of postage options. In addition, Stamps.com only includes the most basic of shipping features. You can purchase postage, schedule pickups, and email return shipping labels, and that’s essentially it.

How much does it cost?

If you consider everything, the cost of using Stamps.com for your USPS shipments isn’t that much. Stamps.com is priced at a flat rate of $19.99/month (in addition to the cost of postage, of course). The fact that every Stamps.com subscription comes with a free shipping scale when you pay shipping and handling is simply awesome. This does help you save a ton of money.

How does it work?

Although Stamps.com has limited features compared to many shipping solutions, the software still performs well within its limitations. Here are a few of the features Stamps.com offers:

  • Bulk Printing Options: Print shipping labels for all of your orders at once (available only with the downloadable PC version).
  • Print Packing Slips: You can only add custom graphics (like a logo) if you’re using the downloadable PC version of the software.
  • Print Postage: You can print shipping labels and stamps. You can also print addresses and postage directly onto envelopes.
  • Send Return Shipping Labels: If your customers request to return a product, you can create a return shipping label and send it via email.
  • Schedule USPS Pickups: Schedule pickup times directly from Stamps.com’s admin panel.
  • Purchase Shipping Insurance: Select this option when you go to purchase postage. You can add insurance for your shipments up to $10,000 in value.
  • Send Notification Emails: Let customers know when their orders have shipped.
  • View Reports: Establish “Cost Codes” to track your purchases and more.
  • Print From Any Printer: You don’t need to buy a fancy printer to print postage.
  • SCAN Forms: Include multiple shipments in one barcode.
  • Thermal Printers: Stamps.com supports the leading brands of thermal printers.
  • Hide Postage Cost: Send labels that do not display postage costs.
  • Advanced Services Available: Sign up for Stamps.com’s Global Advantage Program which gives you access to services for flats and large envelopes, automated customs forms, instant shipping refunds, and better shipment tracking.
  • Support: Contact support representatives with email, live chat, and unlimited telephone support.

Benefits Of Stamps.com USPS 

With all this talk of “limited features,” why would you choose to sign up for Stamps.com? In truth, Stamps.com may not be right for many online sellers. Larger businesses (which often need to purchase postage from multiple shipping carriers) likely require more features than Stamps.com can offer. However, for smaller merchants, Stamps.com might fill a need perfectly. The first benefit of using Stamps.com is the price. At $19.99/month, Stamps.com is cheaper than most other shipping software solutions, especially if you’re shipping between 50 and 500 orders a month. In addition, a subscription with Stamps.com gives you access to discounted shipping rates from USPS. What’s more, Stamps.com is simple to learn. Because it is a bare-bones tool, there isn’t a whole lot to figure out in order to get shipping. What’s more, Stamps.com’s support is reportedly good, and the company does a great job with its support documentation. You’ll be able to find answers to many of your questions with a quick search. Let’s now begin with the updated postage rates.

First Class Mail Letters

We have the most popular letter type, to begin with—First Class Mail. It’s the most economical way of sending small packages like letters, large envelopes, and lightweight and small packages up to 15.99 ounces. When you compare the delivery times with that of FedEx Envelope or UPS Express Envelope, you’d be fairly disappointed since there’s no guaranteed delivery. It typically takes about two to three days for a First Class Mail package to arrive at the final destination.

Updated shipping rates in 2019

  • The First Class Mail letter (1 oz.) rate for postage purchased at the Post Office is increasing by five cents to $0.55 from $0.50.
  • Each additional ounce for a First Class Mail letter will cost an extra $0.15 (a decrease from $0.21 in 2018).
  • First Class Mail Flats/Large Envelope rates are not increasing in 2019, remaining at $1.00 (1 oz.), with additional ounces costing $0.15.
  • Postcard rates are also not increasing in 2019, remaining at $0.35.
  • For customers who print postage online (via Stamps.com), the Metered Mail rate will now be a 5-cent discount compared to the Post Office price with rates increasing to $0.50 in 2019 from $0.47 currently.
  • Each additional ounce will cost an extra $0.15 in 2019, a decrease from $0.21 currently.
  • The five-cent discount for online postage on a one-ounce First-Class Mail letter represents a savings of 9% for consumers and small business owners.

You can easily select the First Class Mail options with the WooCommerce Multi-Carrier shipping plugin. After a successful installation, just hover down to WordPress→Dashboard→WooCommerce→Settings→Multi-Carrier Shipping. Once there, you need to set up the plugin, enter your USPS account details, enter your Stamps.com USPS account details (if necessary), and then define the shipping rules as shown in the image below.


As you can see, the plugin will allow you to display services from both USPS and Stamps.com (in this case, First Class Mail Letter).

Or you may ship everything through the USPS, with the exception of expedited shipments, which you send through FedEx. It all depends on your business model, your average order weight, and your shipping destinations.
