A volatile composition dispenser and methods of volatilizing a volatile composition in the air are provided. The volatile composition dispenser includes one or more reservoirs, with each reservoir containing a volatile composition. Each reservoir has one or more delivery engines disposed in fluid communication with the volatile composition in the reservoir. Each delivery engine is in fluid communication with an evaporative surface. One or more evaporative assistance elements are disposed adjacent to the evaporative surface(s). A method of volatilizing the volatile composition(s) includes operating the evaporative assistance elements with varying energy over a total emission program, including energy boost periods, and extended emission periods of decreased or maintained energy.
