1. A method for specifying email recipients comprising: specifying, via computing equipment executing at least one program that is stored in a non-transitory storage medium, a first set of email recipients within one designation section of a plurality of different email designation sections of a graphical user interface, wherein said email designation sections comprise a TO section and a CC section; designating, via the computing equipment executing at least one program that is stored in the non-transitory storage medium, a user specified set operation, wherein the user specified set operation is typed as text into the one designation section, and wherein the user has an option to specify a Boolean operation as the user specified set operation, wherein said Boolean operation comprises at least one of an exclusion operation and an intersection operation; specifying, via the computing equipment executing at least one program that is stored in the non-transitory storage medium, a second set of email recipients, wherein at least one of the first set and the second set comprise a previously established email distribution list; and automatically generating, via the computing equipment executing at least one program that is stored in the non-transitory storage medium, a third set of email recipients by performing the user specified set operation upon the first set of email recipients and the second set of email recipients, wherein the third set of email recipients includes fewer recipients than the first set, wherein the third set defines email recipients for the one designation section, wherein other ones of the different email designation sections are unaffected by the user specified set operation and by the second set, wherein when the set operation is the exclusion operation the third set consists of recipients in the first set that are not in the second set, and wherein when the set operation is the intersection operation the third set consists of recipients that exist in both the first set and the second set.
