Montana: pen pal rules and how to send mail
Montana prisons reject mail that contains a pen-pal solicitation or that comes from a pen-pal matching service. Being listed isn't against the rules, but writers should send ordinary personal letters and never enclose anything from a pen-pal site.
Where personal letters go depends on the prison: each prison's page below shows its address. They are scanned, and the person receives a copy on their tablet.
