Five years since her release, Maggie Luna has kept the mail she received from family during her two stints in Texas state prisons: drawings from her daughter, a letter from her niece, prayer cards from her mother. “It was something that I was able to open up while I was in prison and just be able to escape for a minute,” she says. But under a new program launching in some Texas facilities this week, prison mail is about to become less personal, as prisoners will no longer be allowed to receive any physical mail from loved ones.
