While I was serving my five years in Federal prison, the BOP rolled out an email system for prisoners. It allows inmates to correspond with friends and families on a more consistent basis. In Federal prison you get 300 minutes of phone calls per month, or about 10 minutes per day. While it was a blessing to be able to speak to my wife almost every day, it was difficult to deepen a relationship or deal with issues that cropped up. Plus, I was shipped off to FCI Elkton in Ohio which was about 9 hours away from home, so our visits were very limited.
It looks like states like Vermont and others are implementing a new email system for their inmates to help improve communications with family. This is a good step forward, but hopefully they will not use it to replace personal visits as some institutions have tried to do with video chat systems. Nothing can replace the personal and intimate moments inmates experience with their family during visits. This should never be replaced by technology.
