Learn whether inmates can send letters to loved ones outside prison, who pays postage, and which services help families stay connected.
Families separated by incarceration often wonder about the basics of staying in touch. One of the most common questions is: "Can an Inmate Send Letters to a Loved One Outside of the Prison do the Inmate Have to Pay?" The short answer is yes — incarcerated people can generally send letters — but whether and how they pay for postage depends on the facility, the person's account balance, and the mail service being used. This article walks through every major mail and messaging service families rely on, what each one costs the inmate, and where to go when the options feel overwhelming.
How Inmate Mail Works in American Jails and Prisons
Mail has been a legal right for incarcerated people for decades. Federal courts have consistently held that prison officials may regulate but not eliminate correspondence between inmates and people in the outside world. This means virtually every county jail, state prison, and federal facility in the United States has some official process for outgoing letters.
The practical mechanics, though, vary widely. A person held in a large county jail may have daily mail pick-up, while someone in a smaller rural facility might have outgoing mail collected only a few times a week. Envelopes and stamps are typically available for purchase through the jail commissary. If an inmate has no money on their books, some facilities provide a small number of indigent stamps each week — usually two or three — at no charge.
Outgoing letters are almost always inspected before they leave. Facility staff may read the contents to check for coded language, contraband communications, or safety concerns. Non-legal mail is not considered private. Legal mail addressed to a licensed attorney generally receives greater protection, and staff are typically required to open it only in the inmate's presence.
Paper Mail Sent Directly Through the US Postal Service
Traditional USPS mail is still the most widely recognized way for an incarcerated person to write to someone outside. The inmate hand-writes the letter, seals it in an envelope, applies a postage stamp purchased from commissary, and drops it in the outgoing mail bin. The letter travels through the regular postal system and arrives at the recipient's home in two to seven business days depending on distance.
The inmate pays for this with funds already on their commissary account. Stamps are sold at face value or sometimes at a slight markup depending on the facility's commissary vendor. A standard first-class stamp currently costs $0.73 through USPS, though commissary pricing may differ. Families should know that if their loved one's account has a zero balance, the inmate may qualify for indigent mail — but rules differ significantly by facility.
Families who want to write back follow a similar process from the outside. They write a letter, address it to the inmate's full legal name and booking number, include the facility's mailing address, and send it through USPS. The letter enters the facility mail room and is scanned or read before delivery.
Securus Technologies and the Role of Private Mail Platforms
Securus Technologies is one of the largest private communications providers in the American corrections industry. The company operates in thousands of facilities across the country and offers multiple ways to communicate with an incarcerated person, including phone calls, video visitation, and a digital mail product called Securus Mail or eMessaging. Families send a message through the Securus online platform and the message is printed by the facility and delivered to the inmate like a physical letter.
Securus's digital mail model allows families to attach photos, which is one reason many people prefer it over plain email-style messaging services. From the inmate side, the cost depends on how the facility has configured the system — some facilities charge the inmate to send a message back, while others allow free outgoing replies. The per-message cost when charges do apply typically ranges from a fraction of a cent to several cents, drawn from the inmate's account.
A common complaint documented in media reporting and regulatory filings is that Securus's fee structures can be difficult to understand, especially for families new to the system. The company has faced scrutiny from the FCC and consumer advocates over pricing and data practices in its communications services. Families navigating Securus for the first time often benefit from a neutral starting point where they can confirm which specific service is active at the facility holding their loved one — something InMato LLC offers through its free county jail inmate search covering 289 systems across 14 states.
JPay and Its Email-Style Messaging
JPay, now a subsidiary of Securus Technologies, operates an email-style messaging system used in many state prison systems. Through the JPay platform, people outside the facility can send electronic "messages" that are delivered to the inmate on a JPay tablet, if the facility provides tablet access. The sender typically pays a small fee per message, called a "stamp," which is purchased in advance. In many systems, an inmate can reply at no additional cost, though this varies by facility contract.
JPay also allows photo and video attachments at additional cost. Some facilities permit e-cards and electronic greeting cards through the platform. The service is especially common in state DOC systems rather than county jails, so families with a loved one recently booked into county lockup may find JPay is not the relevant service for their situation.
The gap families often encounter is figuring out which service is active at a specific county facility. Many jails contract with services other than JPay, and using the wrong platform means messages that never arrive. Confirming the right provider before spending money is a step InMato is specifically designed to help with — the InMato app and website surface official provider information so families avoid wasted time and misdirected funds.
Smart Communications and the "Postal Mail" Model
Smart Communications, operating under the MailGuard brand, has changed how physical mail works in a growing number of jail and prison systems. Rather than delivering paper letters directly to inmates, Smart Communications routes all incoming physical mail to a scanning facility. The letter is opened, scanned, and converted to a digital image. The inmate views the image on a kiosk or tablet rather than receiving the original paper.
This model was adopted by facilities primarily for security reasons — paper mail has historically been a vector for smuggled contraband including drugs embedded in the paper itself. Smart Communications' scanning process removes that risk. The service is generally free for the sender, who simply mails the letter to a processing address rather than the facility directly. The inmate typically receives the digital image within one to two business days.
The implication for families is practical and immediate: if a loved one's facility uses Smart Communications, sending a letter to the old facility mailing address may result in it being returned or rejected. Families need to know the correct Smart Communications processing address for their specific facility, which is usually available on the facility's official website or through a search tool like InMato's free county jail search.
Getting Started: Corrlinks and the Federal Bureau of Prisons
For families with a loved one in a federal Bureau of Prisons facility, the email messaging system is called CorrLinks. This is the federally administered system used across all BOP institutions. CorrLinks allows inmates to send and receive email-style messages with approved outside contacts.
To use CorrLinks from the outside, the person outside must be invited by the inmate first. The inmate initiates contact by submitting the outside person's email address through the CorrLinks terminal inside the facility. The outside person then receives an email invitation and creates a free account. Once connected, messages are typically charged to the inmate's Trust Fund account — current pricing has historically been around five cents per minute of reading time, though the specific rate may change.
Federal inmates are prohibited from initiating a CorrLinks relationship with someone who has not accepted the invitation. This is an important distinction from some state systems where families can sometimes initiate contact through the platform. Families of federal inmates often find the process less intuitive than expected, particularly if their loved one was recently transferred between facilities and access to the terminal is temporarily limited.
Access Corrections and Midwest-Heavy Messaging
Access Corrections is a messaging and deposits platform that operates heavily in Midwestern state and county facilities. It is part of the same corporate family as TigerCommissary and other correctional services products. Access Corrections offers electronic messaging, phone services, and commissary deposit processing within a unified account system.
From an inmate's perspective, Access Corrections messaging typically allows replies from the inmate's account balance. The cost per message or per page varies by facility. The platform's family-facing side allows deposits and messaging in a bundled account, which some families find convenient because they can manage multiple services from one login.
The limitation with Access Corrections, like most single-vendor platforms, is geographic concentration. Families whose loved ones are held in facilities outside the platform's primary coverage area will find the service unavailable. Confirming which platform serves a specific facility before creating an account and depositing funds is the kind of step that saves real money and frustration — it is the exact problem InMato LLC was built to address as an information and referral service that never touches user money.
Pigeonly and Third-Party Letter Services
Pigeonly is a third-party service that allows families outside to type a letter online, and Pigeonly then prints and mails it as a physical letter to the inmate's facility. The sender pays a subscription or per-letter fee. The key advantage is convenience: the family member doesn't need to know specific mailing rules, photo size restrictions, or envelope requirements. Pigeonly handles the printing and mailing on their behalf.
Pigeonly also offers a photo printing service, where families upload digital images and Pigeonly mails printed photos to the inmate. This has been popular because many facilities only allow commercially printed photos of specific sizes, and family members often don't have the equipment to produce a compliant print on their own.
The limitation is that Pigeonly is a paid service on the family side, and the inmate still needs commissary funds to send anything back. There are also documented instances of delivery delays or facility rejections when a specific jail's mail rules conflict with what Pigeonly sends. Checking whether a facility accepts third-party printed mail before purchasing is an important step.
Telmate and Inmate Tablet Access
Telmate, now rebranded under the GTL (Global Tel Link) family, provides tablet-based communications in many county jail and state prison systems. Inmates in facilities with Telmate tablets can compose messages directly on the device and send them to approved outside contacts. Families receive the message through the Telmate app or web portal.
Tablet availability is not universal. Some facilities provide tablets to all housing units, while others restrict access. A person in a higher-security classification may have reduced or no tablet access even in a facility that otherwise uses Telmate. Families should not assume tablet messaging is available just because the facility contracts with a tablet provider.
Messaging through Telmate is generally charged to the inmate's prepaid account. The per-message cost varies by facility contract. GTL has historically been one of the larger correctional communications companies in terms of facility coverage, particularly in county jails, and is frequently mentioned alongside Securus in policy discussions about the cost of incarceration communications.
PhilaPrison and Local Jail Systems with Free Messaging
Some individual county jail systems have moved to free or very low-cost messaging as part of broader decarceration and family-connection initiatives. Philadelphia's jail system has been publicly cited as an example of a large urban facility that has eliminated charges for some forms of inmate communication. Cook County Jail in Illinois and several California counties have also experimented with free or reduced-cost calls and messaging.
These local decisions are made at the county level, and changes happen frequently. A policy that eliminates phone charges one year may not extend to digital mail, or the free messaging program may be discontinued when a facility contract changes. Families who want current, accurate information about what a specific facility offers need a reliable way to look it up.
The broader pattern is important: costs for inmate communication have been a subject of serious federal and state regulatory attention since the FCC began capping rates for interstate calls in 2013 and continued extending those rules. The trend toward lower-cost communication is real, but it is uneven across the country and not yet universal.
Keefe Group and Commissary-Funded Correspondence
Keefe Group is one of the dominant commissary vendors in the United States. While Keefe is primarily known for food, hygiene products, and electronics sold inside facilities, it also handles the account funding that makes inmate correspondence possible. When a family member sends money to an inmate's commissary account, Keefe is frequently the vendor processing that deposit through their ConnectNetwork platform.
The inmate then uses those funds to purchase stamps, envelopes, paper, and pens from the commissary. In this sense, Keefe is a foundational infrastructure layer beneath almost all inmate letter-writing. Without funds in the account, an inmate who has used up any indigent stamps the facility provides cannot send letters unless someone adds money to their books.
Families who want their loved one to be able to write letters regularly should consider making small, regular deposits to the commissary account rather than one large deposit at the start of incarceration. Consistent smaller deposits can be more useful because commissary purchases are often limited per transaction or per week. Using InMato's verified referral links ensures the deposit goes to the official licensed provider — not an imitation site designed to collect payment without forwarding it.
Ameelio: The Free Letter-Sending Nonprofit Model
Ameelio is a nonprofit technology organization that provides free letter-sending and video connection services to incarcerated people and their families. Through the Ameelio platform, families can send printed letters and photos to inmates at no cost. Ameelio absorbs the printing and mailing costs as part of its nonprofit mission to reduce barriers to family contact during incarceration.
The Ameelio model has received significant attention and positive press because it directly counters the for-profit communication model dominant in the industry. The organization has partnered with facilities in multiple states to establish formal relationships. However, Ameelio's free letter-sending is not available in every facility, and families should confirm eligibility before relying on it as their primary communication channel.
Ameelio illustrates a growing counter-movement in the correctional communications space — one that recognizes family contact during incarceration reduces recidivism and supports mental health outcomes for both inmates and their children. That same ethos of removing financial barriers is reflected in InMato LLC's founding principle: InMato Core is free for every family with no time limit, and InMato+ is $19.99 per month per loved one with cancel-anytime self-service cancellation, so families only pay for the alerts and tracking they actively need.
What Indigent Mail Policies Mean for Families
Indigent mail policies exist in most state prison systems and many county jails. An "indigent" inmate is generally defined as one whose trust fund account balance falls below a minimum threshold — often five or ten dollars — for a defined period. These inmates are typically entitled to a set number of free stamps and envelopes per week, provided by the facility.
The specifics vary considerably. Some facilities provide two stamps per week; others offer five. Some require the inmate to formally request indigent supplies through a written form. A few facilities require the inmate to show their account history to qualify. Families who believe their loved one has no funds and cannot afford stamps should ask the inmate to inquire with their housing unit officer or the jail's programs office about indigent mail policy.
Knowing whether indigent mail is available is one more operational detail that falls on the family to research — often while managing the emotional weight of an unexpected incarceration. Tools that make this research faster and less confusing have genuine practical value.
Booking Alerts, Transfer Alerts, and Staying Ahead of the Process
One of the hardest parts of staying connected through letters is that facilities change. Inmates are transferred from county jail to state prison, from one facility to another, and sometimes back to county court holding for hearings. A letter addressed to an old facility often gets returned to sender, and by the time the family realizes the transfer happened, weeks may have passed.
Jail booking alerts — sometimes called booking-watch notifications — are an automated system that tells a family member the moment their loved one is booked into or transferred within a monitored facility. InMato+ includes booking-watch alerts, release and transfer alerts, and court date alerts as part of its $19.99 per month plan, giving families a faster, more reliable way to stay on top of location changes before they interrupt mail correspondence.
Knowing a loved one's current location is the first step before any letter can successfully be sent. The InMato app makes that step free — any family member can search for a loved one in jail at no cost, with no account required. Whether you are trying to figure out how to find someone in jail or confirming where to address an envelope right now, the search starts at inmato.com.
