Get StartedAll the benefits of USPS Certified Mail®. None of the hassle.
No postage meter or Post Office required
Print Certified Mail labels with digital postage on plain paper cover sheets or adhesive labels. Insert the cover sheet with your legal notice, demand letter, or business correspondence into the Certified Mail window envelopes we supply. Leave for your Mail Carrier or drop in any USPS Mailbox for processing through the United States Postal Service.
No more manual forms and green cards
The Proof of Acceptance (Electronic) and Return Receipt (Electronic) are both automatically posted to your account. They replace manual Form PS 3800 preparation, Certified Mail® Receipt Forms, Scan Forms, manifests, Firm Books, and Form 3811 Green Cards.
100% legal compliance
The Proof of Acceptance Electronic is universally accepted as prima facie evidence that the USPS physically took possession of mail at a specific time and date. The Return Receipt Electronic has the same legal standing as the Green Card.

Log in anytime to check or download the USPS Proofs delivery confirmation reports, as well as your mailing costs, digital proof of delivery, and complete mailing history, for each individual mail piece. Eliminates manual filing forever.

Frequently Asked Questions
Can I send certified mail online?+
Yes. With SimpleCertifiedMail.com you can send a certified letter online without going to the Post Office. Create the USPS Certified Mail label with postage on your own computer, print it on a plain paper cover sheet, insert it into a window envelope, and hand it to your carrier or drop it in any USPS collection box. Certified Mail travels as First-Class Mail, so you get a tracking number the moment the label is created, an Electronic Proof of Acceptance when USPS scans the piece, and an Electronic Return Receipt after delivery if you add one. There is no software to install and no monthly subscription.
What does it cost to send Certified Mail online?+
Sending Certified Mail online through SimpleCertifiedMail.com costs $7.48 per piece for a 1 oz letter in a #10 or 6x9 envelope, and $10.39 with an Electronic Return Receipt. That rate is all inclusive: USPS postage, the USPS Certified Mail fee, the window envelope, the tracking number, and 10 years of digital proof records. There are no monthly fees and no subscription.

SimpleCertifiedMail.com is priced for teams that send Certified Mail regularly, at $7.48 per piece with envelopes, tracking, and 10 years of proof records included and no monthly fee. Past a few pieces a month, the saving comes from cutting manual forms, green cards, and Post Office trips rather than from the postage itself.
