A circular mail singulator is provided having a continuous spiral baffle which is disposed immediately above a rotating annular table with a frictional top surface, there being a central cone for the delivery of envelopes into the inner convolution of the spiral and a linear conveyor tangential to the outermost convolution to receive envelopes delivered therefrom and, without interrupting the envelope speed, deliver the envelopes into a stamp cancelling machine.
