About the Email Click Rate Calculator

Click rate is the metric that survived the collapse of open-rate accuracy: a click is a deliberate act that privacy features do not fake. It tells you whether the content and the call to action earned anything.

Enter unique clicks and emails delivered for the click-through rate, then add unique opens for the click-to-open rate — the share of people who opened and then clicked. CTR judges the whole campaign, CTOR judges the email itself once the subject line has done its work, and reading them together tells you which one to fix.
