In a situation where you have to share your mailboxes with a family member or a close friend, it is better to install a Double Mailbox Post. It saves space and looks more immaculate than a single post stuffed with tons of mail. Also, it saves confusion if you are sharing a mailbox and conveniently carries multiple mail, newspapers, and magazines at one time. Not only are these mailboxes an intelligent and advantageous choice for modern people, but they significantly enhance your entrances and curb appeal.
