Admail

Okay, so you know how sometimes you get letters or flyers in the mail from people or companies trying to sell you things? That's called mail advertising or admail!

Basically, companies will send out a bunch of letters or flyers to lots of different people's mailboxes. They do this because they want to try and sell their products or services to as many people as possible.

Sometimes, companies will even create special offers just for the people who get their admail. So if you get a letter from a pizza place, for example, it might have a special coupon just for you to use when you order a pizza.

Some people might not like getting admail, though, because it can sometimes be a lot of junk mail that they don't really want to receive. But other people might find it helpful if they're looking for something specific and an admail comes along offering just what they need!
