Abstract: A method, system and program product allow an originator of an electronic mail message to create and attach different topics to messages. Recipients of messages can view different topics from an electronic mail message and can take actions on specific topics and related content. Electronic mail messages can be organized based on topics. Each topic in a string of electronic mail messages is chain-scoped with its lifetime bounded by an electronic mail chain.
