A newsy letter is a friendly letter from someone you know — a parent, a friend, an aunt — that is full of little bits of news: who is well, who got a job, what happened on the street. It is informal and warm. It is not newspaper news; it is personal news. You would not call a government report newsy, and you would not call a short, cold email newsy either. Though actually, younger people send messages instead of long letters, so the word can feel a bit old, like something in a story — but if you see it, it still means full of chatty updates from home.
