Mail by Pony
Prepare ordinary personal correspondence as printed letters. Create and revise drafts, choose print styles, view exact PDF proofs, and check your order history. Sign in to your Mail by Pony account to access your letters. Supply sender and recipient addresses in conversation and review the exact proof, addresses, and price. When you ask to send, Pony provides a Stripe-hosted payment link. You can also finish on the Mail by Pony website. Printing and mailing are handled manually for U.S. domestic addresses. Handwriting styles are printed fonts. Standard letters do not include tracking or a guaranteed arrival date. Do not submit medical records, government identifiers, payment-card details, passwords, secrets, or other highly sensitive content. This service is not suitable for deadline-sensitive legal notices. Customers may fund a prepaid USD balance and separately authorize an assistant or API key to send within their chosen limits. Connecting an assistant does not grant spending permission. There are no subscriptions, automatic top-ups, or fallback card charges. Developer documentation is available at https://www.mailbypony.com/developers.
