Sending Certified Mail Online

Sending Certified Mail online is a great alternative to traveling to the post office and waiting in line. Both the LetterStream website and our partner site,, allow users to quickly and easily create Certified Mail in a matter of minutes.

Additional advantages include being able to track each letter online without entering the 20-digit tracking number along with the ability to quickly access the USPS signature file. There is no need to buy envelopes, forms, supplies, or stamps!

Simply sign up for a free account at either of our websites (we recommend using for 10 or fewer letters, and for anything more than that, LetterStream has many more options as well). Once your account is created, you’ll simply provide us with the recipient (to) and return (from) addresses (or upload an address list CSV file) and we'll take care of the rest.
