Capabilities and prices
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.
Who sends the mail
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.
What it mails
Letter
A letter printed on 8.5 x 11 in paper and mailed in an envelope. The addresses print at the top of the first page.
- Image: A picture at the top of the letter, or after the signature.
- More pages: Up to 3 pages. Past the first page, the paper is printed on both sides.
- Stationery: A style for the letter: classic, monogram, botanical, celebration, typewriter, handwritten. Classic is a plain page.
- Signature: The person's saved signature, from a photo, printed under the closing.
- Certified mail: Sent as USPS Certified Mail, with or without an electronic return receipt, and signed for at delivery.
Postcard
A postcard with a photo on the front and the message and address on the back.

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.
