We use calculations, in combination with your email campaign activity, to create the valuable percentage metrics you see in your email reports. In this article, we show you where each value comes from and how we calculate each section of the report.

All equations are written as X / Y x 100 = %. If there’s no data available for the Y value, 0 is used.
