In some scenarios, you want reporting data for a specific date and the report comes back with seemingly wrong data after compared to the same report ran on a previous date for the same time period. This discrepancy applies to the reports in Acoustic Campaign with data on open, clicks, soft bounces, and other data.
Data updates when an action to that email happens. The data is current, but the email templates that are chosen are for the date range. Exports can run via RawRecipientDataExport or TrackingMetricExport depending on preference.
For example, a Trend Summary Report is run on 11/3/2012 for emails that are sent between 10/1/2019-10/31/2019. The list of emails is for 10/1/2019-10/31/2019, but the data is through 11/3/2019. Unique Opens are 100. Gross Opens are 200. Unique Clicks are 150. Gross Clicks are 300. The same report is run on 12/3/2019 for emails that are sent 10/1/2019-10/31/2019. The list of emails are for 10/1/2019-10/31/2019 but the data is through 12/3/2019. Unique Opens are 125. Gross Opens are 250. Unique Clicks are 175. Gross Clicks are 350.
