Sorry I'm new to this...what's a snail mail letter?
Martha carefully picked the day she started her incarceration, leveraging technicalities, and got out 4 days early.
Lori left it to chance and ended up spending an extra 3 days in prison. If she had reported to prison 1 day earlier (Oct 29), she would have gotten out 4 days earlier (Dec 24), and been home for Christmas.
If you are facing sentencing, be smart... Figure out the best day to report to prison.
Your best option would be to write them a snail-mail letter and ask them the easiest way to contact them electronically.
