Do you send poo via mail

I think there may be some confusion here!

No, it's not common or acceptable to send poop (feces) via mail. In fact, it's not even possible to send biological waste like poop through the postal service. The postal service has strict guidelines and regulations regarding what can and cannot be sent through the mail, and human waste is definitely not allowed.

Additionally, sending poop through the mail would also pose significant health and safety risks to the people handling the mail, as well as the environment.
