Word allows you to print United States Postal Service approved electronic postage directly onto your envelopes if you subscribe to Stamps.com's electronic postage service and use Stamps.com's add-on software.
If you have used an earlier version of Stamps.com's service, you will need to upgrade to Stamps.com 3.1 or higher.
To sign up with Stamps.com, click E-Postage Properties on the Envelopes tab of the Envelopes and Labels dialog box; click Yes; and follow the Web links and instructions that are displayed in Internet Explorer. After you have successfully signed up for Stamps.com and installed its software, you can add postage to an envelope like this:
With the Envelopes tab of the Envelopes and Labels dialog box open, make sure that the correct delivery address appears in the Delivery Address text box; if it does not, either enter it manually or click the Address Book icon to select it from one of your address books.
Check the Add Electronic Postage check box.
If you want to add special services such as Certified Mail, Registered Mail, insurance, envelope graphics or logos, or postage or mail date corrections, click E-Postage Properties. Then specify the appropriate settings in the Stamps.com dialog box, and click OK.
Stamps.com's online postage service will check your delivery address against the USPS Address Matching System to ensure that your ZIP Code is correct. Click Accept to confirm any adjustments the USPS Address Matching System has made. (If you are sure that a change is incorrect, click Edit to make appropriate changes.)
The Stamps.com dialog box appears. Specify your postage options here, including weight and mailing date.
If you don't have enough postage in your account, you will be prompted to purchase more. Click Buy Postage to do so, using the credit card you have on file with Stamps.com.
Click Print to print the envelope.
