What is the Receiver Operating Characteristic (ROC) Curve?
The Receiver Operating Characteristic (ROC) curve is a graphical plot used to assess the performance of a binary classifier system. It illustrates the trade-off between the true positive rate (TPR) and the false positive rate (FPR) at various threshold settings. In the context of email marketing, it can be used to evaluate the effectiveness of your email campaigns in terms of how well your model can distinguish between subscribers who will engage with your emails and those who won't.
