Mail by Pony

Write to someone inside.

A letter at mail call matters. Write it here. We print it plainly and mail it.

Or draft it with your AI assistant. US addresses only.

  1. Get the exact address

    Find the facility’s mailing address and the person’s ID number on the state corrections website or the Federal Bureau of Prisons inmate locator.

  2. Keep it plain

    Use white paper, a white envelope and a typed font. Skip artwork and the script style, which some facilities reject.

  3. We mail it

    Pony prints it and hands it to USPS with your full name and return address on the envelope, which facilities expect.

For example

Dear [Name],

It was good to hear your voice on Sunday. Mom’s garden finally came in, and the tomatoes are taking over the porch.

[What is happening at home, who says hello, what you are looking forward to.]

I will write again next week.

Love,
[Your name]

Good to know

  • Every facility sets its own mail rules. Read them on the facility’s website before you send, especially for photos and page limits.
  • Some facilities only take mail at a central processing address. If yours does, send it there.
  • Many prisons and jails open, scan or copy incoming mail, and some give the person only a copy. Write knowing staff may read it.
  • Mail that breaks the rules can be returned to your return address or not delivered at all.

Questions

How do I address a letter to a prison?

The person’s full name and ID number, then the facility’s mailing address exactly as the facility lists it. Put both name and number on the recipient line.

Will a typed letter be accepted?

Typed letters on plain white paper are the safest choice. Facilities more often reject colored paper, stickers, cards and anything glued or scented.

Can I send photos?

Often, within limits. Check the facility’s photo rules first. Many limit how many you can send, and some reject photos printed on regular paper.
