States with different mail statutes

The system was not built to help you stay connected

Mail gets rejected for reasons families never see coming. Each facility, each state, each level of government has its own rules.

📜

Facility-Specific Rules

Federal BOP, state DOC, and county jails all have different requirements for envelope marking, content, and approved items. One format does not fit all.

Silent Rejections

Many facilities reject mail without telling families why. MailRight shows you the rules before you send, so your letter arrives the first time.

Appeal Rights You Don't Know About

Most states require written notice when mail is rejected, and you have 15 days to appeal. Families rarely know this. MailRight walks you through it.

🔍

Inmate Address Lookup

Finding the correct facility address and inmate ID is the first hurdle. MailRight provides a searchable directory with verified mailing addresses.

📝

Smart Letter Guidelines

What paper is allowed? Can you include photos? Are stickers okay? The answers change by facility. MailRight gives you a checklist for each one.

📖

Rights in Plain English

First Amendment protections, federal regulations (28 CFR § 540), and state statutes translated from legal jargon into language families can actually use.

How MailRight works

01

Enter the facility

Search by name, state, or type. We cover federal prisons, state facilities, and county jails.

02

Get the rules

See exactly what's allowed: paper type, photos, content restrictions, envelope formatting, and prohibited items.

03

Write with confidence

Follow the facility-specific checklist. No more guessing. No more rejected letters sitting in a return pile.

04

Know your rights

If mail is rejected, we show you the appeal process for that jurisdiction. You have rights. Use them.

A letter should not require a law degree to send

Every rejected letter is a missed connection. Every confusing statute is a barrier between families. MailRight exists because staying in touch shouldn't be this hard.
