Terms of sale

You buy one printed piece and its postage. These are the rules that come with it.

Effective 28 August 2026.

The short version

• Payment starts the printing. After you pay, nobody can cancel, change or recall your piece.
• Nothing reads your message. No person and no software checks it before it prints. What you send is on you.
• One flat price. A card costs $7.00 and a letter costs $5.00, with postage included.
• Delivery is an estimate. First-Class mail carries no delivery guarantee, so no date here is a promise.
• There is no automatic refund. Write to hello@cellpostal.com and the owner decides each request.
• You must be 18 or older to buy, and we mail to United States addresses only.

These bullets are a summary. The sections below are the terms.

What you are buying

One piece, one page, printed and posted. You choose one of two formats.

Card, $7.00

A 5.5 by 4.125 inch card, printed in full colour on 120# uncoated stock. It goes into a plain sealed envelope with the address printed on the front and a real First-Class stamp. A small QR code prints in the corner and links to cellpostal.com.

Letter, $5.00

An 8.5 by 11 inch page, printed in black and white on 24# bond paper. We fold it into a #10 double-window envelope and meter the First-Class postage.

The service checks these limits before you pay:

• The card takes 8 printed lines and 968 characters.
• The letter takes 25 printed lines and 3350 characters.
• A sign-off and a sender name must each fit on one line.
• The press sets Latin-1 text, the character set that covers English and most of Western Europe. Curly quotes, long dashes and similar marks convert for you. Emoji and any other script cannot print, so we name them and stop the piece before you pay.

We post to United States addresses, and the website offers US states only. If the postal service calls an address undeliverable, we refuse the piece before you pay. If the checking service does not answer, we send the piece as you typed it.

Price and payment

• A card costs $7.00. A letter costs $5.00. The price is flat and postage is included.
• There is no tax line and no shipping line. You cannot buy more than one piece at a time.
• Stripe takes the payment. You type your card details on Stripe's own page, never on ours.
• Before you pay, closing the checkout page cancels the piece. We charge you nothing.

Payment starts the printing

Read this before you pay for anything.

The moment Stripe confirms your payment, we render your piece and hand it to the mail house. There is no queue, no hold and no review window.

After that moment you cannot cancel your piece, change it or recall it. Nobody at Cellpostal can pull it back out of the post.

Check the message, the recipient's name and the address while you still can. The payment button is the point of no return.

What you may not send

Nothing in this service reads, screens, filters or moderates your message. No person and no software looks at it before it prints. You carry the responsibility for what you send.

When you buy, you agree not to send:

• threats, harassment or intimidation, of the recipient or of anybody else
• anything that breaks the law
• a message that pretends to come from another person or another organisation
• content that infringes somebody else's rights, such as copyright or a trademark
• mail to a person who has asked you to stop writing to them

We can refuse service, and we can stop serving somebody. That is our right, and it is not a check on your message. No filter enforces this list, so the list binds you.

What you are responsible for

• The address. You type it and you own its accuracy. We print what the address check returns, or what you typed when the check does not answer.
• The message and the signature. You confirm that you have the right to send them.
• Your age. You must be 18 or older, and nothing in the service checks this.
• Your tracking link. Anybody holding it sees what it shows. If you forward it, you share that.

Delivery and tracking

Every timing on this site is an estimate, never a promise. First-Class mail carries no delivery guarantee.

• Your piece enters the mail stream on the next business day.
• Most mail arrives 3 to 5 postal days after the post office takes it.
• Your tracking page shows an estimated arrival date.
• Ordinary post reports through postal sorting and often sends no scan at the door. Your tracking page may never show "delivered", and the piece can still arrive.
• Scans refresh at most every 6 hours, and they stop 30 days after mailing.

Refunds

There is no automatic refund.

If your piece fails to reach the mail house, we email you to say so.

For anything else, write to hello@cellpostal.com. The owner reads every request and decides it one at a time. This page promises you no refund, no window and no amount.

Limits on the service

• You can create 20 pieces per hour from one internet address.
• You can run 60 address checks per hour.
• One purchase buys one piece of one page.
• There is no account, no login and no password. Your tracking link is the only way back to a piece.
• Cellpostal is in beta. We can change the service, and we can stop it.

Your privacy

The privacy page says what we collect, who else sees it, and how long it stays.

The legal part

• We provide the service as it is, and we make no warranty about it.
• Our liability to you is limited to the price you paid for the piece.
• The law of the State of New Jersey governs these terms.
• 250 High Street LLC operates Cellpostal.

Changes to these terms

We can change these terms. The effective date at the top changes with them. The terms that bind your purchase are the ones on this page on the day you pay.
