Can I send an encoded letter to an inmate?

Description : Can I send an encoded letter to an inmate?

Last Answer : This is a very interesting question. I myself have no idea, but I’d imagine they’d reject anything that looks suspicious, so if it’s random gibberish at first glance, they’ll probably know what’s up and reject the letter. If it’s something you could hide within plain text, you might get farther.
