The USPS offers a handy reminder that your mailbox is full if you are sending a letter or package and the red light on the machine flashes. If this happens, your mail carrier will not be able to deposit your mail and will leave a notice in your mailbox. The notice will include the date and time that the carrier attempted to deliver your mail. If you see this notice, you should remove any mail from your mailbox and contact the carrier with any questions.
