when you send a letter to inmate on here do they get notified ? how do know if they received it ?

Inmates are not notified ahead of time when a letter is sent. Your letter is printed and mailed through USPS, and then delivered by the facility’s mailroom during regular mail distribution.

Once it arrives at the facility, it’s inspected and handed out to the inmate, so there isn’t a tracking or notification system on their end.

The best way to know they received it is when they respond to your letter or mention it during a call. Your mail will be delivered, though timing can vary depending on the facility’s mail process.
