Systems and methods herein provide wickless fragrance delivery. In embodiments, fragrance aroma chemicals are delivered from a fragrance oil containing pod or cartridge by applying direct heat to said pod. Upon a particular temperature (or temperature range) being reached, the pod releases fragrance at a desired intensity. The heated pod releases fragrance at a cooler temperature as compared to traditional wax systems, traditional plug-in devices, and/or traditional diffusers. As such, the heater devices of the systems disclosed herein operate at a cooler temperature as compared to traditional fragrance systems. The comparatively cooler temperature makes the devices disclosed herein more energy efficient than traditional fragrance systems. In addition, the pods themselves are more efficient and utilize less fragrance as compared to traditional fragrance systems. Moreover, this device is designed to cycle warmer/cooler temperatures at programmed times. This temperature cycle fluctuates the amount of fragrance released, preventing the oversaturation of fragrance into the environment. This prevention of oversaturation is crucial for preventing human anosmia (e.g., the fragrance is no longer noticeable to the user due to overexposure).
