You've got mail. Home Letter Box

I have "Informed Delivery" from USPS, where they email you images of items arriving in your mail. Here is a link.

Put a bell on it and ask him to jingle it. Push bell https://www.google.com/search?q=push+bell&safe=active&client=tablet-unknown&prmd=sivn&source=lnms&tbm=shop&sa=X&ved=0ahUKEwjTk5z-s9bWAhWo8YMKHcvmCHYQ_AUIEigB&biw=1280&bih=800 yes the old fashioned kind or even a door bell push button works. I have used door bell push buttons when I was injured. You can also have a jingle a bell set-up or a ding a long bell too..

still looking for other ideas .

Perhaps the postman could raise the box's flag (like you would normally do to alert him that you have mail to pick up to go out)?

My husband took a metal spring, put a small ball on one end and spray painted it a brite color. On the opposite side of the flag he attached the other end of spring. At the handle where you pull to open attached a piece of plastic with a notch the size of the spring cut out. So when the mail box is open it springs up, you know when the mail is delivered. Then when you get your mail you just put the spring back in the notch.

Amazon sells these

Baby monitor or intercom , in plastic bag on a hook. He can talk to you.

My neighbor tied a painted whiffle ball to the mailbox door, and put it inside so every time the mailman put the mail in, the ball would come out and hang down so she could see it.

As a retired Postal Carrier I can tell you this... The flag that comes on your mail box should only be used when you have OUTgoing mail.. but due to the on going problem of strangers driving or riding by and stealing mail (hoping to find bill payments with checks) some areas recommend that you place your mail in the box with the stamp facing the door and do not put up your flag. I have used a large binder clip labeled "outgoing mail" to show my carrier that I had stuff to send. NOTE: most carriers WILL NOT sort thru mail that is in the box looking for outgoing stuff.

ANY method you use to show that you have new mail in the box.. should need only ONE had to operate (the other is usually full of other mail)... I have had several of my rural customers use an indicator like the ball one from Amazon, ACE hardware has a similar product.. works when the door is opened to deliver and pick up mail... just remember to reset after you remove your mail from the box. i have also seen customers who put a clear back in their mail box so they could see stuff in .

I'm not sure what it is called or even where it was purchased but my mom and dad have a little device that buzzes that lets them know when the mailman has gone. It is in their kitchen if anyone is interested in this I will find out some more info from them!!😊.

Maybe you could get a wireless door bell for your mailbox

a large colorful magnet

ask the mail person to move it to a visible spot when mail is delivered, you can even write directions on the box or magnet

My Dad had the mail persons to raise their flag, when they delivered. If Dad had mail to go out, the mail person took the mail and lowered the flag. My folks always knew when to go out for the mail.

Ask the mailman the approximate time he delivers the mail. Then go to the mail box 15-30 minutes later. They are on a route and usually deliver around the same time every day.

Look for a mailbox that turns (or create a gizmo that will allow it to turn). After you get the mail turn it sideways. When the mail carrier delivers your mail it has to be turned outwards in order to open the door. If it is facing out, you've got mail.

Many areas with roadside mailboxes have "flags" attached to them. Do as Esther suggested, if this type of mailbox is an option where you live.
