Before you select a rate for a large envelope, you need to determine whether the mailpiece you are sending is a letter or large envelope according to the USPS.

If your mailpiece weighs more than 3.5 oz, the device automatically sets the class to Large Envelope regardless of the dimensions. If the mailpiece weighs less than 3.5 oz but has the dimensions of a large envelope, you need to manually select Large Envelope when you choose the class.


To determine if your mailpiece meets the criteria for a large envelope, use the Postal Advisor app.

To open the Postal Advisor:

  • Tap SendPro Apps on the Home screen, then tap USPS Postal Advisor, or
  • Tap Postal Advisor at the bottom of the Home screen.

The Postal Advisor also provides information for various types and classes of mailpieces, including postcards, letters, and parcels.

 

Weigh the mailpiece and measure the dimensions

  1. Tap Print on Envelopes on the Home screen.
  2. If you have the accounting feature enabled, tap Account and select an account.
  3. Place the mailpiece on the scale. The weight appears. You can also weigh the mailpiece using any other postal scale.
