Print & Mail Envelopes

With Stamps.com, you can print USPS postage directly onto envelopes instead of using NetStamps for letters you are mailing within the United States. When printing envelopes, you can choose to print both the delivery and return address onto the envelopes, in addition to the postage.

You can print to the following envelope sizes:

  • #10, 4 1/8" x 9 1/2"

    Multiple types of #10 envelopes are available to purchase from our online store.

  • #9, 3 7/8" x 9 1/2"

  • #A9, 5 3/4" x 8 3/4"

  • #6, 3 5/8" x 6 1/2"

  • #A2, 4 3/8" x 5 3/4"

  • #7, 3 7/8" x 7 1/2"

  • #11, 4 1/2" x 10 3/8"

    #11 Certified Mail envelope option available

  • #12, 4 3/4" x 11"

  • Custom-size envelopes are also available when using Stamps.com PC software

Additional services like C.O.D, certified or registered mail, return receipts, non-machinable mail, and insurance are also available when creating and printing envelopes through Stamps.com.

Before You Begin

There are a few things to know before you print envelopes with Stamps.com.

  • Stamps.com Connect is required for printing envelopes with Stamps.com Online unless you are using Chrome as your browser. If you are using Chrome, be sure to enable the print option Allow printing on envelopes without Stamps.com Connect in your Stamps.com account. Go to Settings > Mail > General.

  • You cannot print international postage directly on an envelope with Stamps.com. To mail international letters, use NetStamps instead.

  • We recommend printing a sample envelope to ensure your printer settings are configured and your envelopes are loaded correctly.

    If you are using the Stamps.com PC software, use the Printer Configuration Wizard from the Tools menu to configure your printer for envelope printing.

  • You can print multiple envelopes at once if they are all the same size, weight, and service class.

  • USPS Flat Rate Envelopes are useful for important documents because they include tracking and are considered Priority Mail. However, while they are called envelopes, you cannot use the envelope printing option in Stamps.com for them. Instead, create a shipping label if using Flat Rate Envelopes.

  • Large Envelopes/Flats are often used for manuscripts, reports, contracts, legal documents, and any document that cannot be folded. You cannot print postage directly on this type of envelope. Instead, use NetStamps or shipping labels for Large Envelopes/Flats.

Access to the Reprint Option

The Reprint option appears after each print occurs. Please note you have one opportunity to reprint. Do not change any settings or go to another screen. Doing so will disable the Reprint feature.

Print Envelopes in Bulk

To create multiple envelopes at once, you'll add multiple recipients to your Ship To field. You can add them manually or add them from your Contacts list. You'll then prepare the shipment as you normally would.

When creating envelopes in bulk, all envelopes must be the same size, weight, and use the same postage rate. If you are unsure of the weight of the envelopes, be sure to weigh them before preparing postage.

To add recipients from your Contacts list, click the Mail To link (if using Stamps.com Online) or the Contacts button (if using Stamps.com PC software) and then select the recipients from the Contacts pop-up.

If you frequently mail or ship to the same individuals or companies in your contacts list, create Groups so you can add them all to your mass mailing more quickly.

Customized Envelopes

With Stamps.com PC Software, you can print postage on non-standard-sized envelopes and postcards and change font, size, or color for return or delivery addresses.

PC Software Only

The ability to create custom layouts is not available in the Online version of Stamps.com.

Create a Custom Envelope Size

To create a custom envelope size, you'll need to create a custom layout. Once created, your custom layout will be available to select from the Printing On drop-down menu.

  1. Go to Envelopes.

  2. Click the envelope icon next to the Printing On drop-down.

    This will open the Custom layout Designer.

  3. Click Create New.

  4. Select your mailpiece type, enter a name for this layout, and click Next.

  5. Specify the height and width of your custom envelope, then click Next.

Your new custom envelope will now appear in the Printing On drop-down menu when you are using the Envelopes tool. Our software will notify you if a custom envelope size is larger or smaller than the USPS regulation or if the envelope size will result in a postage surcharge.

We recommend printing a test envelope when you first create a custom layout. Load an envelope in your printer, select your printer, and set your paper feed option. Click Next.

Our print wizard will ask a series of questions to make sure the sample prints properly. Answer each question and click Next.

If your custom-size envelope is not printing correctly, please call customer support for assistance from one of our printing specialists.

In the Custom Layout Designer window, you can also rename, edit, or delete the layout.

Custom Envelope Options

You can change the font, size, or color for return or delivery addresses on an envelope with Stamps.com PC Software.

Please keep in mind that USPS uses specialized scanning equipment to automatically read addresses. Although your printer may support many fonts, a simple sans-serif font with a point size of no less than 10 will increase the address readability, decreasing the chance of delivery errors.

Font Size Must Adhere to USPS Guidelines

If you choose a font too large to print due to the length of your address, the font size will be automatically set to allow printing within USPS Guidelines.

  1. Go to Envelopes or Packages.
