Frequently asked questions

Everything you need to know before sending your letter.

Is Certified Mail sent online legally valid?

Yes. Your letter is printed, sealed, and handed to USPS as genuine Certified Mail. You receive proof of mailing, then the Electronic Return Receipt with the recipient's signature. These documents are accepted by courts, government agencies, and landlords, exactly as if you had waited in line at the post office.

How does the Electronic Return Receipt work?

When the letter is delivered, USPS captures the recipient's signature. That signature certifies the exact date of receipt. The Electronic Return Receipt is then stored in your account, ready to download at any time. It is your proof that the letter was received, and when.

How long does delivery take?

Your letter is printed and handed to USPS the same business day if you complete your order before 2:00 PM ET, or the next business day otherwise. USPS typically delivers Certified Mail within 3 to 5 business days, though delivery times are set by USPS and not guaranteed.

How can one flat price cover everything?

We batch the printing, sealing, and mailing of thousands of letters every day. That volume lets us negotiate costs, so one all-in price covers what the counter itemizes: postage, the Certified Mail fee, and the return receipt, plus the printing, envelope, and trip the counter leaves to you. Counted all-in, you come out ahead, while skipping the line and filling out forms by hand.

What happens if the recipient is not home?

USPS leaves a notice in the mailbox. The recipient then has 15 days to pick up the letter at their local post office. If they do not claim it, the letter is returned marked unclaimed. That marking is also proof: legally, unclaimed Certified Mail is considered to have been presented.

What file formats do you accept?

You can upload PDF, JPG, PNG, or TXT files, up to 11 pages per Certified Mail envelope (printed double-sided). Longer documents, up to 33 pages, are automatically sent as up to 3 separate letters, each with its own tracking and proofs. Your document is converted and laid out automatically. You see an exact preview before paying: what you see on screen is exactly what will be printed.

Can I write my letter directly online?

Yes. Our built-in editor lets you write your letter without leaving the page. You can start from a ready-made template (demand letter, lease termination, complaint, notice) or use our AI writing assistant to word your request correctly.

How do I track my letter?

Every letter appears in your account with its real-time status: printing, mailing, in transit, delivered. Your USPS tracking number is provided and every step is timestamped.

How does the membership work and how do I cancel?

There is no commitment. You try the service with your first letter, paid at its all-in price, then the membership renews automatically at $49 per month with 10 letters included each month (any sending type, Certified Mail with Electronic Return Receipt included). You can cancel anytime, in two clicks from your account, with no reason or fees required. Cancellation takes effect at the end of the current period.

Can I cancel my order or get a refund?

As long as your letter has not gone to print, you can cancel it free of charge from your account. If your letter is not mailed for any reason, you receive a full refund. Once the letter is printed and handed to USPS, the service has been performed.

Are my documents secure and confidential?

Yes. Your documents are encrypted in transit (HTTPS) and stored on secure servers. Only the automated print pipeline accesses them, just long enough to produce your letter. Nobody reads your mail. You can request deletion of your documents at any time.

When exactly does my letter go out?

You pick the mailing date at checkout: as soon as today (before 2:00 PM ET) or the next business day, or a later date if you prefer to schedule the mailing. Your letter is printed and handed to USPS on the chosen date, and your proof of mailing shows that date.
