CTR in email marketing stands for click-through rate, and it’s the rate at which your recipients click on the clickable elements in your email, such as links and buttons. A high CTR means your recipients are actively clicking on those elements, and therefore your copies and calls to action (CTAs) are effective. Meanwhile, a low CTR means the opposite. The average CTR for all industries is 2.44%; however, anything above 1% is generally acceptable.
