What continent is mail in

I think there may be a bit of confusion here!

"Mail" is not a continent. A continent is a large continuous area of land, such as Africa, Asia, Europe, North America, South America, Australia, Antarctica, and Oceania.

"Mail" refers to a system of sending and receiving letters, packages, and other items through a network of postal services. It's a way of communicating and exchanging goods over long distances.

So, to answer your question, "mail" is not a continent.
