Jeffrey compares version A versus version B and asks respondents which email would make them more likely to book, with an optional demographic focus by factors like age, gender, income, and party. He runs a flash review with 50 respondents targeting Columbus, Ohio (with other U.S. pools available). The test serves 25 database respondents per version, synthesizes the results, and returns a recommendation in as little as a few seconds, typically in 5 or 10 seconds.
