Click-Through Rate (CTR)

Also known as: CTR, Click Rate

Percentage of delivered emails where someone clicked a link. It is a simple way to see how many people move from reading your email to taking action.

Click-through rate is the share of people who get your email and click a link. It tells you who cared enough to do something, not just open the email. You compare clicks to delivered emails to get the number. People often shorten it to CTR.

CTR matters because it shows if your content is actually useful. High opens with low clicks usually means the email did not match what people expected. Marketers track CTR to compare subject lines, offers, and layouts over time. It also helps you spot when a list is getting tired or no longer engaged.

Start by watching CTR on a small, engaged segment of your list. Try one clear call to action in each email and make the button easy to see on mobile. If CTR drops, test a new angle, shorten the copy, or send to a smaller group. Over time you will learn what your audience actually wants to click.
