If you don’t need a signature, the cost is $5.24 (a 28% savings), and you receive the Proof of Delivery (Electronic) within 24 hours of your letter being delivered.

Plus, our USPS-approved Certified Mail window envelopes are provided to you at no charge, adding another 15¢ to 20¢ to your savings. And you’ll receive automatic refunds for Certified Mail letters you prepare but don’t mail. For many clients, that’s as many as 5% of the Certified Mail pieces they prepare.

You simply print Certified Mail® cover sheets from your home or office printer, complete with electronic postage. Tuck the cover sheets and your letter into the window envelope we provide, drop in any mailbox, or leave for your Mail Carrier to pick up. Clients report saving 80% and more on labor which can easily be $3 to $4 per piece of Certified Mail.

Simple Certified Mail

The Proof of Acceptance (Electronic) PDF is posted to your account within hours of mailing, soon after the letter receives its first scan at a USPS facility. The Proof of Acceptance (Electronic) is accepted by the IRS, state and federal courts as prima facia evidence that the Post Office took possession of the Certified letter at a specific date and time. No more Scan Forms, Manifests and Firm Books.

Certified Mail Proof of Acceptance

Once your mail piece is delivered, the Proof of Delivery (Electronic) or Return Receipt (Electronic) are posted to your account within 24 hours. No more waiting days for Green Cards to be returned and having to file them in cabinets and closets. The USPS Return Receipt Electronic® has the same legal status as the PS-3811 Green Card.
