Personal letters and pen pal mail, minus the errand
By Justin Winter · Updated September 16, 2026
The short answer
You can type a personal letter, have it typeset in a handwriting-style font, and mailed anywhere in the US via USPS for $0.99 — a real paper letter in the mailbox, sent from your phone in about 90 seconds.
Usually the right pick: First-Class · $0.99
Some letters should be paper: the note to a grandparent who does not do email, the pen pal exchange, the letter to a friend going through something, the "open when" letter, mail to a summer camper. The recipient gets an envelope with their name on it — an increasingly rare and genuinely felt thing.
The handwriting-style fonts (free) are the right register for personal mail — "Handwritten casual" for warmth, "Neat" for legibility for older eyes. It is typeset rather than pen-written and we are upfront about that; what lands emotionally is the physical object and the words, and those are fully yours.
For recurring correspondence — a weekly letter to a parent in assisted living, a monthly pen pal exchange — prepaid credits (with up to 35% bonus) mean no checkout each time, and the letter history keeps your thread. Some people dictate the letter to their AI assistant, which sends it through our MCP endpoint; the words are still theirs, the licking of stamps is nobody’s.
One honest limitation: this is US-only mail today, up to 12 pages, text documents only — no photo prints yet. For enclosing photos, a traditional envelope still wins.
Questions before you send
Why not go to the post office myself?
You can. paperplane does not replace the post office; it replaces the trip. USPS still carries the letter. What you skip is the printer, the envelope, the stamp and the walk to a mailbox. $0.99 covers all of it.
If something goes wrong, do I pay?
If we cannot mail the letter, the hold on your card is released and you are not charged. If a letter fails after your card is charged, you are refunded automatically and in full.
Can the recipient tell it was sent through a service?
The letter arrives printed in your chosen style in a windowed envelope with your return address. It is clearly printed mail, not pen-on-paper — think of it as typed correspondence with warmth, in the tradition of typewriter letters.
Can I send letters internationally?
Not yet — US addresses only at launch. International First-Class is on the roadmap.
Is there a cheap way to write weekly?
Prepaid credit packs add up to 35% bonus balance, bringing a weekly $0.99 letter down meaningfully. Codes work at checkout with no card needed.
