Performance analysis is the backbone of successful email marketing campaigns. Among the many metrics to track, open rates and click-through rates often take center stage.
But should you focus on Click-Through Rate (CTR) or Click-to-Open Rate (CTOR)?
With an average CTOR of 10.5% and a good CTR between 2-5%, choosing the right metric can make all the difference.
While open rates reveal how many recipients view your email, the true measure of engagement lies in clicks.
So, Let’s dive into the differences between Click Through Rate vs Click To Open Rate and explore which one is the best for your email marketing strategy.
What is Click-Through Rate?
Click-Through Rate (CTR) measures the percentage of recipients who click on a link within your email.
It’s a key metric that shows how well your email content and call-to-action (CTA) encourage your audience to take action.
For example, as an online business trainer, if you send an email promoting a new course, your CTR will show how many recipients clicked on the link to learn more or sign up.
The higher your CTR, the more effective your email content and CTA are in driving interest and action.
How to Calculate Email Click-Through Rate?
To calculate CTR, simply divide the total number of clicks on your email links by the total number of emails delivered, then multiply by 100 to get the percentage.
This shows you how effective your email is at driving clicks.
Formula: CTR = (Total Link Clicks / Total Delivered Emails) x 100

For example, if 1,000 emails were delivered and 100 recipients clicked on the links, your CTR would be 10%.
A high CTR shows that your content and CTA are resonating with your audience, making them take action.
On the flip side, a low CTR could mean your email isn’t clear or persuasive enough.
A CTR also helps in evaluating the effectiveness of different elements such as subject lines, CTAs, and overall content within the email.
What is the Click to Open Rate (CTOR)?
Click-to-Open Rate (CTOR) measures the percentage of recipients who clicked on a link within your email but only considers those who actually opened it.
It helps you understand how well your content engages recipients who took the time to open your email.
For example, as an instructor promoting a new course, if 100 people opened your email and 20 clicked to learn more, your CTOR would be 20%.
A higher CTOR means your email content is effectively encouraging action from those who opened it.
How to Calculate Email Click to Open Rate?
CTOR is calculated by dividing the total unique clicks by the total unique opens and multiplying by 100 to get the percentage.
Formula: COTR = (Unique Clicks/Unique Opens) × 100
![Email Click Through Rate vs Click to Open Rate – Differences & Uses [2025] 11 Email Click To Open Rate](https://getwpfunnels.com/wp-content/uploads/2023/12/Email-Click-To-Open-Rate.webp)
Suppose you send out an email campaign to 500 subscribers. Out of these, 400 subscribers open the email, and 100 of them click on a link within the email.
In that case, your COTR would be (100/400) x 100 = 25%, indicating that 25% of the recipients who opened the email also clicked on one or more links.
Why are CTR & CTOR Important?
Let’s explore why these marketing metrics matter and how they can provide valuable insights to boost your email marketing success
CTR (Click-Through Rate):
- Measures how well your entire email, including the subject line and design, drives clicks.
- Helps evaluate the overall effectiveness of your email campaigns.
- Crucial for tracking actionable engagement, like sales or registrations.
CTOR (Click-To-Open Rate):
- Focuses on how engaging and relevant your email content is to those who open it.
- Highlights the efficiency of your email in transitioning recipients from opens to clicks.
- Helps identify areas to improve user experience and content quality.
Tracking both gives a complete view of your email performance and helps you refine your strategy for better results.
Factors Influencing CTR and CTOR
Several factors influence both Click-Through Rate (CTR) and Click-To-Open Rate (CTOR) in email marketing campaigns.
i. Email Subject Line
The subject line is crucial in determining open rates, which directly impacts CTR and CTOR. If your emails aren’t opened, there’s no chance for clicks, and a low open rate will likely lead to a low CTR.
A low CTR could mean your subject line isn’t compelling enough. To figure out where the issue lies, you need to look at both open rates and CTR together.
If you have a low CTOR, it means your email body isn’t engaging enough, as CTOR only measures clicks from emails that were opened.
For better results, make sure your subject line grabs attention and your email content keeps readers interested, improving both click rates and click-through rates.
ii. Call to Action (CTA)
A clear, compelling CTA in your email helps encourage recipients to take action. The placement and wording of your CTA impact both CTR and CTOR.
Action-oriented phrases like “Shop Now” or “Get It Now!” can drive clicks and improve engagement.
If your click rate vs open rate is low, it could indicate that your CTA isn’t strong or clear enough.
A strong CTA can also improve your email click to open rate, making it more likely that recipients will open and take action. Always test and refine your call-to-action for better results.
iii. Email Content Relevance
![Email Click Through Rate vs Click to Open Rate – Differences & Uses [2025] 12 Click Through Rate vs Click to Open Rate](https://getwpfunnels.com/wp-content/uploads/2025/01/02.-Click-Through-Rate-vs-Click-to-Open-Rate-.webp)
Relevant content is key to boosting engagement. When your email content matches your email recipients’ interests, it increases both CTR and CTOR.
Providing valuable information and aligning it with your audience’s preferences will drive more visitors, clicks, and actions.
Focusing on relevant content helps reduce unsubscribes and keeps your audience engaged. This applies to your newsletter as well.
For many customers, creating content they care about helps improve your ideal CTOR and keeps them engaged with your entire email.
iv. Design and Layout
Visually appealing emails that match your brand’s style can grab your audience’s attention and encourage them to engage.
Using high-quality images and a clean layout makes a great first impression, which can boost your click rates.
When the design stays consistent, your audience is more likely to have a positive experience, leading to a higher CTR and CTOR.
v. Personalization
Personalized elements and dynamic content that cater to the recipient’s interests or past behavior can boost engagement.
You can send out personalized recommendations and indicate to their past purchasers to make the customer feel special.
At the same time, addressing recipients by their name, greeting them on their birthdays and special events, and offering solutions to their pain points are great ways to connect with them.
vi. Email Sending Time
Optimizing email sending time is important when you are collecting leads for a long time.
If you send an email to people at 3 AM, chances are most of them will not open the email at all.
Rather, sending it early morning, or during the afternoon after lunch are ideal times to send emails for higher opens & higher click rates.
vii Email Frequency
The frequency of your emails is another important factor you should worry about.
If you send too many emails in a short time, initially, you will notice high open rates but with low click rates.
But eventually, you will notice fewer and fewer emails opened and increasing unsubscribe rates.
So, unnecessarily high email frequency will annoy your subscribers and impact all your email metrics negatively.
Key Differences Between Email Click Through Rate and Click to Open Rate
Aspect | Click Through Rate (CTR) | Click to Open Rate (CTOR) |
Calculation | Total clicks divided by the number of delivered emails | Total clicks divided by the number of unique email opens |
Focus | Indicates the effectiveness of the call-to-action (CTA) and overall engagement | Reflects the engagement with email content regardless of the number of links clicked |
Influence of Open Rate | Doesn’t consider unique opens | Considers unique opens as the denominator for calculation. |
Measurement of Engagement | Measures the performance of the email in driving clicks | Measures how engaging the content is after it’s opened |
Affected by Link Placement | Affected by the number and placement of links | Not influenced by the number of links; focuses on engagement within the opened email |
Purpose in Assessment | Helps in evaluating the success of the CTA | Assesses the relevance and appeal of email content |
When to Prioritize Click Through Rate vs Click to Open Rate
![Email Click Through Rate vs Click to Open Rate – Differences & Uses [2025] 13 Click Through Rate vs Click to Open Rate](https://getwpfunnels.com/wp-content/uploads/2025/01/Click-Through-Rate-vs-Click-to-Open-Rate-1.webp)
When deciding whether to prioritize CTR or CTOR, it really depends on your campaign goals and what insights you’re looking for.
Using both metrics together gives you a more complete understanding of your email performance.
If you’re looking for actionable engagement, like driving sales or registrations, focus on CTR.
It shows how many recipients opened your email but also clicked on a link. CTR is also helpful when testing elements like button colors or imagery.
On the other hand, prioritize CTOR if you want to focus on content relevance and how well your email resonates with your audience.
CTOR shows how many of those who opened your email actually clicked. It helps you optimize the transition from open to click.
In short, there’s no need to choose one over the other, you should track both to improve different aspects of your email campaigns.
Best Practices to Improve Email Engagement Metrics
No, let us look at a few best practices that you should follow to improve email engagements.
i. Craft compelling subject lines and CTAs for higher click rates
Your subject lines and CTAs are the keys to driving engagement. Use personalization, curiosity, or urgency to grab attention and boost your click rate and open rate. Keep subject lines short, clear, and spam-free.
For example, a subject line like, “Last Chance: Save 50% Today!” paired with a CTA like “Claim Your Discount” can improve your email click-to-open rate.
Remember, a strong subject line boost opens, while a clear CTA drives click. Balancing both is essential for better results in your click rate vs click through rate comparisons.
ii. Conduct A/B testing based on CTR and CTOR data insights
Analyzing your CTR and CTOR helps you make smarter decisions for your email campaigns.
With A/B testing, you can experiment with subject lines, CTAs, content layouts, or visuals to see what resonates best with your audience.
For example, you might test two subject lines to find which one drives a higher click-through open rate. Or, try different CTAs to see what encourages more clicks.
By refining these elements based on real data, you’ll create emails that engage recipients and improve your overall campaign performance.
iii. Personalization strategies to enhance CTR and overall campaign success
Personalization is a game-changer for your email campaigns. Addressing subscribers by name or recommending products based on their previous purchases can boost both CTR and CTOR.
For even better results, segment your list by factors like location or purchase history. This way, you can send emails that feel more tailored to each group, increasing open rates and click-through rates.
Remember, personalized emails create stronger connections with your audience, giving you the edge when comparing CTR vs open rate to improve overall performance.
Conclusion
In conclusion, both click through rate (CTR) and click to open rate (CTOR) are essential for evaluating your email marketing efforts.
CTR shows how well your email engages all recipients, while CTOR highlights how relevant your content is to those who actually opened it.
To truly optimize your email performance and boost conversions, I recommend tracking both.
By paying attention to click through rate vs click to open rate, you can fine-tune your strategy for even better results.
