Send a real postcard online
By Justin Winter · Updated October 17, 2026
The short answer
Write your message, add the address, and paperplane prints and mails a real postcard through USPS. A 4x6 postcard is $0.99, a 6x9 is $2.99 and a 6x11 is $3.49, with printing and postage included.
How it works
- Pick a size. 4x6 for a note, 6x9 or 6x11 when you want more room for the message and the image.
- Write the message and add the address. The preview shows the card as it will print.
- Pay one price. Printing and postage are included in the price shown.
- We mail it. We print the card and hand it to USPS.
What it costs
| Service | Price |
|---|---|
| 4x6 postcard | $0.99 |
| 6x9 postcard | $2.99 |
| 6x11 postcard | $3.49 |
Who it is for
- You want a postcard to arrive without buying a stamp or finding a mailbox.
- You are sending one or a few, from a phone, a script or an AI agent.
When it is not the right tool
- You need a postcard in an envelope; a notecard is the better fit (see the notecard page).
- You are planning a large marketing campaign with list targeting.

Questions before you send
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.
Is postage included?
Yes. The price shown covers printing and USPS postage.
Can a postcard be handwritten?
Postcards are printed. For a handwritten look, use a notecard, which has a pen-written option.
Can I mail postcards to many people?
Yes, through the API or a CSV mail merge.
