Question: What’s a conversion 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
Conversion rate measures whether email engagement led to the intended business outcome after the click. It is tied to the goal of the campaign, such as a form submission, purchase, registration, or download. In HubSpot, marketing email analytics help connect email performance to downstream actions. This makes the metric useful for evaluating whether the email drove meaningful results beyond opens and clicks.
Why the other options are incorrect
Successful deliveries is incorrect because that describes delivery performance, not goal completion.
Undelivered emails is incorrect because that describes bounces, not conversions.
Click-through rate is incorrect because it measures link engagement, not completion of the next desired action.
