I recently logged into the United Stated Postal Service (USPS) to check some shipping rates, and there was an ad on the USPS Homepage for a product called Informed Delivery notifications. Informed Delivery is a really cool service that sends you an email with the pictures of the mail you are going to receive that day in your mailbox!
I really love this product, because when I work late I can see in advance if there is anything in my mailbox worth stopping for on my way home. If there’s not, I just head home and pick up the mail on another day. Another benefit is you can see if the Postal Carrier didn’t deliver all your mail. There is an option to notify the Post Office if you didn’t receive a piece of mail. Here is an example of what the email header looks like and a example of the image you’ll receive of your mail:
