InmateAid has a service where the inmate can respond to your letter. We receive many letters to our members who have kept their address private. We scan the inmate letter and upload it into your account. We charge $1.49 to retrieve the letter. It has created a "pen pal"-like community - you can write somewhat anonymously and the inmate has a way to stay in touch, however you control the situation with InmateAid being in-between.
