How to calculate Click To Open Rate
An email campaign goes out to 1,000 recipients. You achieve an Email Open Rate of 20%, which means 200 people now see the content of the email. Because of your content, 50 people -- 25% -- click on a link. This is your CTOR. Taking this one step further, you can now also calculate your Click Through Rate: 25 people of the initial list of 1,000 clicked through, giving you a CTR of 2.5%.
