USPS Certified Mail
Upload a PDF and
send Certified Mail
Send one-off certified letters in the dashboard or support high-volume notice workflows by API. Corvo prints, packages, and ships via USPS Certified Mail, then keeps USPS acceptance, delivery attempts, signer data when available, mailing-record summaries, evidence bundles, and shipped-retention records attached to the shipment.
Not just a label printer. Full-service Certified Mail.
Corvo handles document printing, packaging, USPS Certified Mail submission, milestone capture, exportable evidence, and staff-managed shipped retention. The browser and API are two submission methods into the same certified-mail system.
USPS Certified Mail options
Request USPS Return Receipt service when your workflow needs stronger delivery evidence in addition to Certified Mail tracking.

Certified mail workflow
Certified Mail when you need proof, API when you need scale
