A job function is a standard way of classifying contacts in an organization by their role or what they are responsible for. Job functions are general classifications used for selection purposes. They do not always correspond exactly to titles. A title is the precise set of words on someone's business card. It is also the set of words that appear under a person's name on a mailing label.
Titles are specific to the individual person.
Even individuals with seemingly unrelated titles may be classified as a Marketing Manager if they have responsibility for marketing. Note that each of our data providers classifies their contacts in their own way. You may add criteria at any time before purchasing your list. Each time you make a selection, your criteria will be added to your current selection list on the left side of your screen. Simply click on any item to delete it.
