Bulkmail III lets you maintain multiple mailing lists in a single file and discriminate between them or combine parts of them at will by using sixteen "switches," plus various other discriminators combined in instantly selectable "filters" that you define and name. The system has a "template" that lets you automatically repeat common things such as a city name and partial zip code as you enter records.
