The Infomed Delivery mail is just an email you receive that shows a picture of your mail & or packages you should receive that day.
No it does not help with mail not recieved. You have to wait so many days before you can report it as not received.
I have done this with several pieces of mail we never received. The Post Office never sent me any type of reply regarding the lost mail. We have never received any of the lost mail.
When I called to ask about it they said they cannot do anything about it unless that piece of mail has a tracking number?
LOL!!! If it's lost it's lost you may or may not get it. Nothing you can do about it.
