How to Set Up and Use E-Postage in Word and Office
Question details
The user wants to know how to purchase and print electronic postage directly from their office applications.

- Product
- Microsoft 365
- Device & OS
- not provided
- Scenario
- Trying to print shipping labels or envelopes with valid postage directly from a word processor.
- Observed behavior
- Microsoft Office does not offer a native built-in e-postage purchasing feature and requires external integrations or third-party software.
Ensure you have an active account with a supported third-party e-postage provider (such as Stamps.com or Pitney Bowes) and that your printer is properly configured with the correct label or envelope sizes.
Install a Third-Party E-Postage Provider Add-in or Software
Since Office does not include native e-postage, you must use software provided by external e-postage services to integrate with your word processor or print directly.
Microsoft 365 applications rely on external vendors for digital postage. You will need to download the official software from a certified provider to manage your postage purchasing and printing workflows.
Select a certified electronic postage provider (like Stamps.com) and create an account on their official website.
Download the provider's official desktop application or their specific Microsoft Office add-in from their support page.
Run the installer. If an Office add-in is available, make sure Microsoft Word is completely closed during installation so the integration can be successfully added to your toolbar.
Open the e-postage software, log into your account, and set up your printer preferences to match the exact dimensions of your labels or envelopes.

Print Envelopes First, Add Postage Later
If you prefer not to install third-party add-ins, you can print standard addresses using Mail Merge in your word processor and apply physical postage or use the provider's web interface.
Use WPS Office for Seamless Mail Merge and Label Printing
While external software handles the purchasing of e-postage, you still need a reliable word processor to format envelopes and print address labels. WPS Office is a lightweight, fully compatible, and free alternative to Microsoft Office that perfectly handles Mail Merge, labels, and envelope formatting.
- 1. Download WPS Office: Visit the official WPS website, download the free suite, and install it on your computer.
- 2. Open Your Label Templates: Launch WPS Writer and open your existing .docx label or envelope templates to prepare your mailings.
- 3. Print and Apply Postage: Use the seamless print dialog to output your documents flawlessly before applying your third-party e-postage.

Frequently Asked Questions
Why is there no E-Postage button in my Microsoft Word?
Microsoft discontinued native integrated e-postage features in newer versions of Microsoft 365. You now need to use a third-party standalone application or a specific add-in provided directly by your postage service.
Which e-postage providers are compatible with Windows and Office?
Popular providers include Stamps.com, Pitney Bowes, and Endicia. Compatibility varies by version, so always check the provider's official website for specific Windows OS or Office add-in support.
Can I use Mail Merge with third-party e-postage software?
Yes. Many standalone e-postage applications can import address lists directly from Excel (.xlsx) or CSV files, allowing you to print the delivery addresses and the postage simultaneously through their proprietary software.
How do I fix e-postage printing alignment issues?
Alignment issues are usually caused by incorrect paper size settings. Check the printer properties in your e-postage application and ensure the digital label or envelope size exactly matches the physical media loaded in your printer tray.
