You can send letters to inmates electronically through a handful of approved messaging services, but the letter doesn’t arrive as paper in their hands. It’s delivered as a digital message on a tablet or kiosk inside the facility, and whether your loved one can read it depends on the rules at that specific jail or prison. The process is faster than mail and often cheaper than a stamp plus a trip to the post office, but it comes with its own set of frustrations that families run into constantly.
Is sending a letter online the same as mailing one?
No, and this is where most of the confusion starts. When you mail a letter the traditional way, it goes through the facility’s mail room, gets inspected, and eventually reaches your loved one as paper. When you send a letter electronically, it goes to a company’s servers first. That company then pushes it to a tablet, kiosk, or sometimes a printed copy at the facility, depending on how that location handles digital mail.
Some facilities print electronic letters and hand them out. Others only allow viewing on a device. A few don’t allow electronic letters at all, even if they allow messaging. You won’t find one universal answer because the rules are set by the facility or the state department of corrections, not by the messaging company.
What you should expect: your letter shows as sent, then as delivered, then as read. If it sits in sent for a day or two, that’s usually normal. If it sits for a week, something is wrong, and you should contact the service’s support rather than the facility directly.
Why does my letter get rejected or delayed?
Rejections are the number one source of family frustration. The reasons are usually boring and consistent. Content that mentions anything about escape, contraband, or violence gets flagged. Photos with nudity get blocked. Sometimes a message gets held because it includes a link, or because the facility’s review queue is backed up.
Another common issue: you write a long, emotional letter and it gets cut off or returned because it exceeded a character limit. Many electronic systems cap letters at a certain length, and the limit is often lower than what you’d write on paper. If you’re used to sending three-page handwritten letters, you’ll need to adjust.
Also, some facilities only allow electronic letters from approved senders. If you’re not on the list, your letter may be rejected without much explanation. The fix is usually to call the facility’s inmate accounts office or check the messaging service’s help page for that specific location.
How much does it cost to send letters electronically?
Costs vary by service and facility. Some charge per message or per photo. Others bundle messaging into a monthly fee. You may also see fees for adding funds to the inmate’s account, which is separate from the cost of sending a letter.
InmateDB, for example, charges $19.99 per month with a 5-day free trial. That covers sending messages, photos, and letters online. If you’re comparing options, look at the total monthly cost for the volume you actually send, not just the per-message price. Families who write daily often find a flat monthly plan cheaper than paying per letter.
One more thing: the inmate usually can’t reply through the same electronic letter system unless the facility allows outbound messaging. In many cases, they can send a short text to a U.S. or Canada phone number, but longer replies may still come by mail or a phone call. That asymmetry surprises people.
What can I actually send in an electronic letter?
Text, mostly. Photos are often allowed, but they get screened. You can usually include a few images per message. What you can’t send is anything that would be contraband in paper form: no cash, no stamps, no stickers, no perfume, no drawings with hidden meanings that a reviewer might flag.
Some services let you send a digital greeting card or a formatted letter with a header. Others keep it plain. InmateDB includes messages, photos, and letters in its monthly plan, and the inmate side includes things like a private journal, email, Wikipedia, dictionary, news, sports, lessons, trivia, and AI chat. That’s not the same as receiving your letter, but it gives your loved one more to do with the device than just read and reply.
Will my loved one actually get to read it?
Yes, if the facility supports electronic letters and your account is in good standing. The catch is that they need access to a tablet or kiosk. If the facility’s devices are limited, or if your loved one is in a housing unit without them, your letter may sit unread for a while.
This is why some families do both: they send an electronic letter for speed and a paper letter for reliability. The electronic one often arrives first. The paper one is the backup. If you’re worried about a specific deadline, like a court date or a holiday, send both and don’t rely on either alone.
What should I do next?
Start by finding out what the facility actually allows. Call the inmate accounts office or check the facility’s website for a mail and messaging policy. Ask specifically whether electronic letters are permitted, whether photos are allowed, and whether there’s an approved sender list.
Then pick one service and test it with a short letter. Don’t write a long, emotional first message. Send something simple, confirm it gets delivered and read, and then decide whether the cost and speed are worth it for your situation.
If you want a straightforward option that covers messages, photos, and letters in one place, InmateDB is worth a look. It’s $19.99 per month with a 5-day free trial, and it also gives your loved one access to email, a private journal, and educational content on the inmate side. But check your facility’s rules first. No service can override them, and the last thing you need is to pay for something your loved one can’t use.
