Can I print the label directly on my envelope?
Our labels are designed to print on plain 8.5" x 11" paper. Even if you're using your own envelope, you'll want to print the label on plain paper and affix to the outside of your envelope.
USPS requires the GREEN banner to be visible on the top of the front and back of each Certified Mail letter. This green banner ensures the letter will stand out in the mail stream so that USPS employees easily recognize it as special service mail which will ensure you receive all the tracking scans for your mailing.
