A mail stack unloading device for use in a mail stacker to unload a stack of mail pieces in the mail stacker. The mail stacker has a pair of stack supports, located at a small angle from a vertical line, for supporting the mail stack as the mail pieces enter the mail stacker along a stacking path when the stack supports are in a stacking position. The stacker also has a platform or tongue connected to the stack supports such that the platform is positioned beneath the mail stack below the stacking path. During unloading, the platform is caused to move upward beyond the stacking path in order to engage with the stack, allowing the stack to be lifted. Then the stack supports are caused to forward beyond the vertical line in order to tip the lifted stack into a container.
