Abstract: A system and method for efficiently generating calls-to-action using progressive filtering. A method includes determining whether messages are eligible or ineligible for response, wherein determining whether each message is eligible or ineligible for response further includes applying eligibility rules defining criteria for determining that a message requires further action. A first set of filtered messages is created by filtering each message which is determined to be ineligible for response. The first set of filtered messages is clustered into clusters based on contents of the first set of filtered messages. Redundant tasks are identified in at least one first cluster. A second set of filtered messages is created by filtering a portion of the at least one first cluster including the redundant tasks. Calls-to-action are generated based on the second set of filtered messages.
