Once Upon a Letter is operated by Mintinny LLC (Mint in NY), a United States company based in New York. Contact: reply to your order email.
A digital, personalized letter (and matching certificate) written with the help of AI from the details you provide, delivered as a private web page that you can print or save as a PDF. Nothing is mailed. Letters are a make-believe keepsake for family use.
If you are not happy with a letter, reply to your order email within 14 days and we will rewrite it or refund your purchase.
This site is intended for adults. We do not knowingly collect information from children. To write a letter we ask you, the adult, for a child’s first name and the details you choose to share, plus your email address. We use them only to create and deliver your letter and to answer your questions. We do not sell personal information or use it for advertising. Letter details are sent to our AI provider (Anthropic) to write the letter, payments are handled by Stripe, and email is sent through Resend. To have your order details deleted, reply to your order email.
Please share only details you are comfortable seeing in a printed letter, and do not submit information about children who are not in your care. We may decline or refund orders that ask for unkind or inappropriate content.
Santa Claus, the Tooth Fairy and similar folk characters are part of shared tradition. We are not affiliated with any brand or trademarked character.
