Tips to start exchanging mail with inmates:
>Step 1 - Research your target
If I am mailing Gary Ridgway, who feels guillty about his crimes, I won't talk to him the same as if I am mailing Armin Meiwes.
>Step 2 - Research the state/country laws about mailing inmates
I sent a letter to Gary Ridgway who is incarcerated in Washington. If I want to send him money so he can buy chocolate and stamps to mail me back, I have to use services like JPay. They won't allow cash-in-enveloppes and many other things so check out.
>Step 3 - Establish contact
You know who and where so now, figure out what. Let's say my inmate is Charles Manson. Charlie doesn't like fangirls and lunatics. Charlie likes music and nature. You could send him a postcard of a landscape.
>Step 4 - The Wait
If you did things right, they will mail you back. Most of them are bored and will do whatever it takes to engage conversation with normies out there or help out troubled fellows.
>Precautions
-If your inmate is a psychopath, You're talking to a psychopath, so try not to talk about them in your first letter or upset them. People like Manson won't think twice about handing off your letter and its contents to other inmates who will play mind games with you.
-Don't get too involved, lie but keep track of your lies so you don't get caught up in them and you know what you said to whom.
-The inmates have no obligation to respond so you may leave empty-handed but you can always try again at another moment.
