The Performance over Time graph shows the number of opened and clicked emails for all sends or for the last send (as set in the date filter). This report shows non-unique open and click events. This means that if a recipient opened the email three times, three events will be shown. Hover over any point in the graph to see the open and click count for that point in time.
The initial view is of the first 24 hours. For mass email, the first 24 hours are of interest as they enable to establish the peak time that the email was opened.
Use the scroll bar below the graph to scroll and zoom to different time frames. You can also drag over an area of interest within the graph, such as a peak, to zoom into it.
Note: The Performance over time report shows data of maximum one year.
