Dear XX,
I'm writing here to tell you that if there's nobody at your home,please pay attention to the Notice Left issued by post office.

I mail packages for overseas clients, customers, sometimes at the post office will issue a Notice: Left.
I prepared in after delivery, writing in English, if the clients inform customers home sometimes no one, please Notice the post client note Left? The best is the habit of Europe
