About us
Who we are
certified-mail-online.com is an online service for sending USPS Certified Mail with Electronic Return Receipt. You write or upload your document, we print it, seal it, and hand it to USPS, which performs delivery. Your proofs (proof of mailing, signed Return Receipt) are stored in your account for 3 years.
We are a private, independent commercial service. USPS® and Certified Mail® are registered trademarks of the United States Postal Service. This website is a privately operated service and is not affiliated with, endorsed, or operated by USPS. Our role ends at preparing and handing off your letters; transport and signature capture remain performed by USPS, which gives your mailing the same legal standing as one sent from a Post Office counter.
Our editorial methodology
Our guides support real-world steps with real consequences: a badly timed notice or an incomplete letter can be costly. So we apply a simple rule: every factual claim is checked against current official sources (statutes, agency rules, USPS publications) before publication.
- The statutes and sources we rely on are cited at the end of each article in a “Sources and references” box.
- Each guide displays its publication date and last update date; we review content whenever the rules change.
- We do not provide individualized legal advice: our guides describe the general framework and are no substitute for consulting an attorney about your specific situation.

Certified Mail guides and mailing compliance
Our editorial team specializes in USPS Certified Mail workflows: proof of mailing, Electronic Return Receipts, demand letters, and mailing deadlines. Every guide is checked against current USPS mailing standards and published rates before publication, then reviewed again whenever prices or procedures change.
