CertifiedMailStream
Prepare, track and manage Certified Mail from any browser.
CertifiedMailStream is the simple, secure way to prepare, track and manage accountable mail. It runs in a browser with nothing to install. Enter an address, or batch-print from the address book or an imported file, and press print. The address is validated against USPS CASS data first, so a missing suite number is caught before the letter goes out and the address is standardized with ZIP+4.
Print the Certified Mail cover page with its barcode on plain paper and insert it into a double-window Certified Mail envelope, or print a thermal label and apply it. The service then generates USPS Form 3877, the firm mailing book, with every tracking number filled in; present it at the post office for the dated postmark that is your proof of mailing. From there, a tracking email arrives each time a letter is delivered, and the signed return receipt sits in your dashboard as a PDF.
