Click-Through Rate (CTR)
Click-through rate is the share of delivered emails where someone clicked a link.
Click-through rate is the number of emails with a click divided by the number delivered. It tells you how many people took action, not just opened.
Because it counts against everyone who got the email, it measures the whole campaign: the subject line that earned the open and the message that earned the click.
