Question: What’s a click-through rate?
- The percentage of successful deliveries post-send
- The percentage of emails that are undelivered and returned to the sender
- The percentage of recipients who clicked a link in your email out of those who opened it
- The percentage of email recipients who completed the desired action after clicking on a link within the email
Explanation
Click-through rate is an email performance metric that focuses on post-open engagement. In HubSpot, it helps show whether opened emails are compelling enough to drive link interaction. This metric is different from delivery, bounce, and conversion metrics because it measures engagement inside the email experience. It is useful for evaluating content relevance, link clarity, and CTA effectiveness.
Why the other options are incorrect
Successful deliveries is incorrect because that describes delivery performance, not link engagement after opens.
Undelivered emails is incorrect because that describes bounces, not recipient interaction.
Desired action completed is incorrect because that describes conversion behavior after the click, not email click engagement.
