Final answer:
Physical Evidence is not added to the list of marketing mix ingredients when marketing services are developed and delivered.
Step-by-step explanation:
In marketing services, the element that is not added to the list of marketing mix ingredients is Physical Evidence.
The marketing mix is a framework that includes Product, Price, Place, Promotion, and Physical Evidence. While Physical Evidence is an important element in marketing tangible products, it does not apply to services.
Physical Evidence refers to the tangible aspects that support the service being offered, such as the appearance of the service facility or the physical cues that customers can see or touch. Services, being intangible, do not have physical evidence as part of their marketing mix.
