Why do I need a return address on my envelope?
You don't need a return address on your envelope if you send a letter through the United States Postal Service. However if you use our website, LetterStream.com, we do require a return address for your envelope. We need this in order to comply with specific USPS rules due to the way we submit mail to them.
If your letter doesn't have a return address or has a deceptive return address, we just might hold up your mail until we contact you for clarification. To see other items that may violate our user agreement, please review the details on our shopping cart/check out page.
