Early on, Airspeed promoted the Envoy by entering individual aircraft in air races and performing numerous long distance flights. The specialised Viceroy derivative, being tailored towards racing, was used in this promotional campaign as well. Production of the Envoy was produced in three distinct series; initial production aircraft lacked several of the features present on later-built examples, such as trailing edge flaps. Seventeen Series I Envoys were completed, followed by thirteen Series II aircraft (equipped with split flaps) and the improved Series III, of which nineteen were constructed. Akin to the preceding Courier, a 'colonial' model of the envoy was developed for overseas customers.
