How to Print Certified Mail® Using Stamps.com

1. Connect to Stamps.com to print Certified Mail®. Our free software (download here) connects you to your Stamps.com account where you can print Certified Mail®.
2. Click on “Envelopes” from the left navigation bar.
3. Select “Letters” as your Mailpiece type.
4. Enter the weight of your mailpiece.
5. Select your printable choice. From the “Printing On” list, select Stamps.com’s pre-formatted Certified Mail® envelope or form.
6. Specify the required address information for your mailpiece.
7. Select your mail class
   Keep in mind that only First-Class® and Priority Mail® are options when you use a Certified Mail® form or envelope, and USPS regulations prohibit reusing forms already used for mailing.
8. Choose additional services
   At this point, you may select options such as Return Receipt and Restricted Delivery. Depending on your chosen services, unused portions of the form may contain the word VOID when printed.
9. Print
   Load the form into your printer, then click “Print Postage”.
   We recommend you print a sample on a blank sheet of paper so you know the correct loading direction for the form.
   Remember, the method of affixing the Certified Mail® form to your mailpiece will depend on any additional services you selected in Step 8. Pay close attention to the directions printed on the form to ensure you affix it properly to your mailpiece.
