Click To Open Rate (CTOR)

Click to open rate shows how many people who open your email then click on a link. It sits between open rate and click rate. You only look at people who actually opened the email. That keeps the focus on how good the content is once someone is inside.

It matters because it tells you if your email delivers on the promise of the subject line. A strong click to open rate means your copy, layout, and offers make sense to the reader. A weak click to open rate can point to boring content, unclear calls to action, or messy design. Most teams use it to see which emails truly move people to act.

For example, if 100 people open an email and 25 click a link, your click to open rate is 25 percent. You can try changing the main button text, moving it higher in the email, or cutting extra links to raise that number. Track click to open rate by segment, campaign type, or email template so you know what actually works for your list.
