Start by getting the addressing details right. Use his full legal name exactly as the facility records it, include his inmate/prisoner ID number if available, and write the prison or detention facility name and full mailing address precisely. If anything is missing or slightly wrong, the letter can be delayed, returned, or not delivered.
Write in a simple, steady structure so you don’t get stuck. Open with something warm and direct, add one or two everyday updates, include a short emotional check-in, ask a couple of easy questions, and end with reassurance. Clear, normal language is best—especially when someone is incarcerated and reading time may be limited.
Avoid things that can slow down screening. Many facilities review mail, so skip anything that looks like coded messages, instructions, or discussions that could create problems for him. If you’re mailing it yourself, keep the format plain: normal paper, no perfume, no stickers, no clips, no extras.
