What are unique clicks?
Unique click is a metric that shows how many recipients clicked on your links. This does not include the number of times each individual may have clicked on a link but instead is only measuring unique opens. So, for example, if one reader clicked on a unique link six times, it would still count as only one total number of clicks. This metric is a great building block to later determine your click-through rate (ctr), total opens, and other metrics.
