InmateAid tracks the outgoing side of the process, not the delivery confirmation at the facility end. Here is what that means in practice.
When you place an order, a confirmation email goes out with the details of what was sent and when. From there, everything ships through the United States Postal Service, and standard USPS transit times apply. The general window is two to three business days from the date of mailing to reach the facility's mailroom, though destination and distance affect that.
Where the mail originates depends on what you sent. Letters and photos go out from Miami, Florida. Postcards and greeting cards ship from San Francisco, California. Magazines come directly from the publishers, so delivery times on those vary more widely depending on the publication and where your facility is located.
Once the mail arrives at the facility it does not go straight to your inmate. Every piece of incoming mail gets opened and inspected by corrections officers before it is distributed at mail call. That inspection process adds a day or two in some facilities depending on volume and staffing. A busy mailroom on a Monday after a weekend can back things up noticeably.
The honest answer is that there is no delivery confirmation once mail enters a correctional facility. The most reliable way to know something arrived is to ask your inmate directly on their next call or in a return letter. If you sent something and significant time has passed with no acknowledgment, contact InmateAid at aid@inmateaid.com and the team will look into it and resend at no charge if necessary.
