# Letter IRL

> Letter IRL prints physical letters and postcards and mails them with USPS to addresses in the United States. A person writes the mail with an AI assistant connected to Letter IRL, checks a preview, and sends it.

A person sends each piece of mail. Where the assistant shows the Letter IRL preview card, they press Send on it; elsewhere the assistant gives them a link to the Letter IRL website, where they sign in, check the mail and press Send. An assistant prepares previews but cannot send mail by itself.

A preview is free. It shows the mail as it will print, and its price. Nothing is printed or charged until the mail is sent.

## Delivery

- USPS First-Class Mail: Mailed in 1-2 business days; usually arrives in 1-2 weeks.
- USPS timing varies and can take longer. USPS does not guarantee a delivery date for First-Class Mail.
- USPS Certified Mail; USPS Certified Mail with an electronic return receipt: USPS timing varies and can take longer. Certified mail is signed for at delivery; if no one signs for it or collects it from the Post Office, USPS returns it to the sender.
- Arrival date: A person may give the date the mail should arrive by. Letter IRL holds the mail and sends it to the printer early enough that it aims to arrive by then; the date is a target, not a guarantee. At most 60 days ahead.

## Limits

- Addresses: The recipient and the return address must both be in the United States. Each piece of mail goes to one recipient.
- Letter length (3 pages): The most pages a letter may take. The words must fit on them; the preview lays the letter out and says when it does not fit.
- Postcard message: The message must fit on the back of the postcard beside the address. The preview says when it does not fit.
