 Keeping your audience in mind while you write can help you make good decisions about what material to include, how to organize your ideas, and how best to support your argument.

Hey there,
You will know whom you are writing to. For example a formal letter to your teacher or a informal letter to your friend. You will know what kind of tone you are supposed to use, like a polite, kind, friendly, aggressive and many more.

Hope this helps :))
