Before you send

How much does it cost to send a letter?

A one-page letter costs $9.04 by Certified Mail, or $12.24 with an electronic Return Receipt. That is USPS postage at USPS's own price, printing and the envelope, and our 10% fee. Longer letters cost a little more. You see the exact total, including any sales tax, before you pay. There is no account to open and no monthly fee.

Our service and policies

What happens after I pay?

We check the letter, our printing partner prints it and hands it to USPS, and the letter's page shows each step with USPS tracking. We email you the link to that page when you pay, and again as the letter moves. We don't promise a delivery date.

What is an electronic Return Receipt?

It is USPS's record of delivery, including the recipient's signature, sent electronically instead of on a green card. It appears on your letter's page once USPS provides it.

USPS Domestic Mail Manual 503

What if the recipient refuses the letter or never picks it up?

The recipient may refuse a letter when USPS offers it. If no one is there to sign, USPS leaves a notice, and a letter that isn't picked up or redelivered goes back after 15 days. Either way, USPS returns it to the return address on the envelope, and tracking shows what happened. No one can make the recipient sign.

USPS Domestic Mail Manual 508

What if my letter is not mailed?

If we don't mail your letter, you get a full refund, including our service fee. You can cancel on the letter's page before it goes to our printing partner. Once USPS accepts the letter, we don't refund it, including if the recipient refuses it or doesn't pick it up.

Full refund policy
