First, take a breath. A month without a response does not mean what you are afraid it means.
Getting adjusted to incarceration is genuinely hard in ways that are difficult to explain from the outside. The first weeks and months inside are disorienting, humbling, and emotionally exhausting. Some people shut down. Some are too proud to show vulnerability in a letter. Some are still trying to figure out who they are in this new environment before they can reach out to the people they care about most. It is not always about you, even when it feels that way.
There are also practical reasons a letter might not have arrived or been responded to yet. Mail gets delayed, misrouted, or held up in mailroom processing. If your inmate was moved to a different housing unit or facility around the time you sent it, it may not have reached them at all.
The advice here is simple: be persistent. Send another letter. Make it warm, make it real, include a photo if you can. Not a letter that demands an explanation for the silence, but one that shows you are still there and still thinking about them. That kind of steady presence from the outside means more than most inmates will admit, especially in the early stretch of a sentence when everything feels uncertain.
If staying connected through letters is something you want to keep doing, InmateAid makes it easy to send letters and photos without the hassle of printing and mailing yourself. Keep reaching out. Patience and persistence are the two things that actually work here.
