Letter Writing Guide

How to write to an inmate — a complete guide for first-time pen pals.

What to say, what not to say, formatting rules by platform, and how to build a real friendship through letters. Written by a ministry that's been doing this for years.

Writing your first letter

The first letter is the hardest. You're writing to someone you've never met, you want to be encouraging without being corny, friendly without being weird, and you don't know what they'll think of you. That's normal. Everyone feels that way.

Here's the structure that works for most first letters:

  1. Introduce yourself, briefly. Your first name, where you live (just the state — never your full address), what you do (general — "I work in healthcare" not your employer's name), and one or two interests. Two or three sentences total.
  2. Tell them why you're writing. "I'm writing through Jeff's Second Family because I read your introduction letter and it stuck with me." Be honest. They can tell when you're not.
  3. Respond to something specific from their intro letter. Did they mention they like to draw? Read? Their faith? Their family? Pick one thing they wrote about and ask a follow-up question or share something related from your own life.
  4. Share one ordinary thing. What you did this weekend, something funny your kid said, a meal you cooked, the weather. Keep it real.
  5. Close warmly, not stiffly. "Looking forward to hearing back from you" is fine. "Praying for you in this season" is fine if it's authentic. "I hope this letter finds you well" sounds like a robot. Avoid that.

Aim for one full page, handwritten if you're using mail, or about 250–400 words if you're using a digital platform. Less than that feels like you didn't try. More than that on a first letter feels overwhelming.

What to say

The thing most first-time pen pals get wrong is overthinking the content. They want to send something meaningful — and meaningful, to them, sounds like a deep thought or a Bible verse or an inspirational quote.

What inmates actually crave is ordinary. The world they're in is the same color, the same sounds, the same routine, day after day. The most precious thing you can send is a window into a life that looks different.

"Tell me what you had for dinner. Tell me about your kid's school play. Tell me what color your kitchen is." — written by an inmate to a new pen pal who kept apologizing for "boring" letters.

Topics that work consistently well

What not to say

✓ Do

  • Be specific (not "we had dinner" — say what you ate)
  • Ask follow-up questions
  • Share photos when allowed
  • Reference what they wrote in their last letter
  • Be honest about your pace
  • Treat them like a friend, because they are one

✗ Don't

  • DO NOT open with "I'm so sorry you're going through this"
  • DO NOT ask about their case unless they bring it up first
  • DO NOT try to fix them or counsel them
  • DO NOT promise frequency you can't keep
  • DO NOT share your home address, phone, employer, or e-mail address
  • DO NOT send anything that violates platform rules (more below)

Two more things to avoid that don't fit neatly in a list:

Don't moralize. Even if they tell you something they did or are struggling with. Their lawyer, the courts, and the system have all weighed in. They don't need another voice telling them they should have done better. Your job is to be a friend, not a judge.

Don't disappear. If you decide not to continue the correspondence, end it through your dashboard so the ministry can let them know respectfully. Never just stop writing. Mail call where their name doesn't get called for weeks, after a relationship started, is one of the most painful things you can do to someone in prison.

A sample first letter

Here's roughly what a first letter looks like when it lands well. Names changed, but this is close to a real one.

Sarah → Marcus, October 2025

Hi Marcus,

My name is Sarah and I'm writing through Jeff's Second Family. I'm in my late thirties, I live in northern Michigan, and I work as a nurse in a small clinic. I have two dogs and zero patience for cold weather, even though I've lived here my whole life.

I read your introduction letter last week and what stuck with me was when you wrote about teaching yourself guitar from a book your mom sent you. I tried to learn guitar twice in my twenties and gave up both times — partly because I had so many other distractions, partly because I was bad at it. The fact that you've stuck with it for years now, with no internet to look up tutorials, says something about you that's hard to fake.

What kind of music do you play? I grew up on Springsteen and Tom Petty in my dad's old pickup, but lately I've been listening to a lot of bluegrass — Tyler Childers especially. Do they let you listen to music in there?

This past weekend I made my grandmother's apple pie for the first time. It's one of those recipes where everything is approximate — "a handful of flour," "enough sugar." It came out lopsided but tasted right. The dogs got the crust trimmings.

I'd love to hear back from you when you have time. No pressure on the timing — I can imagine mail call works at a different pace than my email.

Take care,
Sarah

What that letter does well: introduces her without giving away identifying info, references something specific from his intro letter (the guitar), shares an ordinary detail (the pie), asks an open question, and closes without being saccharine.

Platforms by state

The platform you'll use depends on what state the inmate is in and what the prison allows. Your dashboard tells you exactly which one applies for your match. Here's the quick reference:

PlatformWhere it's usedFormatCost
Securus Texas (and many other state systems) Electronic messages, sometimes with photos ~$0.05–$0.50 per message
TextBehind Many county jails and some state systems You type online, they print and deliver $0.50–$1.50 per letter
GettingOut Some state and county systems (run by GTL/ViaPath) Electronic messages ~$0.10–$0.40 per message
CORRLINKS Federal Bureau of Prisons (BOP) Email-style messages ~15¢ per message + 30¢ per photo (non-Federal inmates), paid by the volunteer
ConnectNetwork Many state and county systems (also run by ViaPath/GTL — sibling to GettingOut) Electronic messages, deposits, phone funding ~$0.25 per message (1 credit = 1 message)
SMARTINMATE (Smart Communications) Several state systems (esp. mail-replacement programs) You upload mail, they scan and deliver; photos supported ~$0.50 per message (50 credits) + 100 credits per photo
USPS (regular mail) Many state and federal facilities still accept it Handwritten or printed letters One stamp + envelope

Each platform has its own quirks — character limits, photo rules, prohibited topics. The volunteer dashboard has step-by-step setup guides for each one. We won't make you figure them out alone.

Formatting rules that apply almost everywhere

Whatever platform you use, these rules apply at most facilities:

A note on monitoring

Everything you write to an inmate is read by prison staff or the platform's compliance team before it reaches them. Same for everything they write to you. This isn't something to be paranoid about — it's just reality. Write like you'd write any letter that someone else might read, and you'll be fine.

When their replies are hard to read

This catches first-time pen pals off guard, so it's worth saying plainly: the replies you get back may sometimes be hard to read.

Hard in the literal sense — the handwriting, especially from older inmates or those with limited education, can be a workout. Hard in the emotional sense — they may write about loneliness, grief, regret, hope, or fear that doesn't have anywhere else to go. Hard in the spiritual sense — sometimes the gap between your life and theirs feels enormous, and you don't know what to say back.

What helps:

Staying faithful long-term

The hardest part of pen pal ministry isn't the first letter. It's the twentieth.

The first letter is exciting. So is the first reply. By month four or five, the novelty has worn off, your life has gotten busier, and writing the next letter feels more like an obligation than a calling. This is the moment most pen pals quietly stop.

Here's how to make it past that point:

If you do this faithfully — even at a slow pace — over months and years, something happens that's hard to describe. The person on the other end stops being "an inmate" and starts being someone you genuinely care about. The letters get easier to write because you're just catching up with a friend. And one day you realize you're not doing this as ministry anymore. You're doing it because they're part of your life.

That's the goal. Friendship is the thing.
