The Net Promoter Score report gives a full history of NPS scores submitted by users of all accounts, including score submit date, user email as well as the comment associated with each score. The detractor/promoter calculation displayed on the top is based on the scores received within the last 90 days of the latest score, including the latest score. You can quickly review and filter NPS responses from your customers by a particular account segment, timeframe, and survey name. You can export the filtered results as a CSV file. 

You can use the Account Lists dropdown to filter this report by any predefined account list. 

The overall NPS score across all accounts is calculated as the Promoter % - Detractors %. This is the NPS score for the entire organization/product based on the list used in the filter.
