CTOR, or Click Through Open Rate, is a key performance indicator (KPI) that helps businesses measure the effectiveness of their email campaigns in terms of engagement.
It’s not just about how many recipients opened the email, but more importantly, how many of those who opened the email were motivated enough to click on a link within it. In essence, CTOR provides a deeper understanding of the relevance and appeal of content to the audience, bridging the gap between initial interest (open) and deeper engagement (click).
Key Takeaways
- Definition: CTOR (Click Through Open Rate) measures the percentage of recipients who, after opening an email, were motivated to click on a link within the email.
- Calculation: CTOR is determined by dividing the total number of email clicks by the total number of email opens, then multiplying the result by 100.
- Strategic Importance: CTOR provides insight into the relevance and appeal of email content, helping organizations measure the bridge between initial interest and deeper engagement.
- Optimization Strategies: Improving content relevance, optimizing design elements, creating clear CTAs, and refining segmentation are critical steps to increasing CTOR.
- Limitations: CTOR may not directly correlate to sales, may be skewed by content or low open rates, and may not be comparable across campaigns or industries.
- Complementary Metrics: CTOR should be analyzed alongside metrics such as open rate, bounce rate, unsubscribe rate, and conversion rate for a comprehensive evaluation of email campaigns.
Why does Click Through Open Rate matter for your business?
For businesses leveraging email marketing, CTOR is essential for various reasons:
- Content Relevance: A high CTOR indicates that the email content is relevant and resonates with the audience, prompting them to explore further.
- Campaign Effectiveness: CTOR can serve as an immediate metric to assess the effectiveness of specific campaigns, helping businesses tweak content or design for better results.
- Engagement Analysis: While open rates give an overview of initial interest, CTOR dives deeper into how effectively the email sustains that interest, pushing users to act.
- Optimization: By comparing CTOR across campaigns, businesses can identify what type of content, call-to-action, or design works best for their audience.
- Segmentation Strategy: Low CTOR can be a cue to revisit segmentation strategies, ensuring that the content is tailored to specific audience segments for higher engagement.
How to calculate Click Through Open Rate (CTOR)?
Explanation of the parts of the formula:
- Total Email Clicks represents the number of times recipients clicked on a link or multiple links within an email. This metric gives insight into how effective the email content was in driving recipients to take a desired action, such as visiting a website or availing an offer.
- Total Email Opens is the total number of times the email was opened by recipients. This metric gives an idea about the effectiveness of the email subject line or sender name in enticing the recipient to open and view the email content.
- The ratio generated by dividing Total Email Clicks by Total Email Opens gives us the percentage of people who, after opening the email, were intrigued enough by its content to click on one or more links. This value lies between 0 and 1 (or 0% to 100% when expressed as a percentage).
- Multiplying the previously calculated ratio by 100 converts the decimal value into a percentage.
In essence, the CTOR (Click through Open Rate) indicates the effectiveness of the email’s content in driving recipient engagement after the email has been opened. A high CTOR suggests that the email content was compelling and relevant, while a low CTOR may indicate that the content didn’t resonate with the recipients or wasn’t compelling enough to drive them to take action.
Example Scenario
Let’s say over the course of a week:
- Your email campaign reached 5,000 recipients.
- Out of these 5,000 recipients, 2,500 opened the email.
- Of those who opened the email, 500 clicked on one or more links within the email.
Insert the numbers from the example scenario into the CTOR formula:
- CTOR = (500 / 2,500) × 100
- CTOR = 0.20 × 100
- CTOR = 20%.
This indicates that 20% of the recipients who opened the email were engaged enough by its content to click on a link, showcasing the effectiveness of the email’s content in driving actions.
Tips and recommendations for increasing Click Through Open Rate
To increase the click-through open rate (CTOR), companies should focus on improving the quality of email content, optimizing design elements, and refining call-to-actions:
Engaging content
Engaging content is the backbone of every successful email marketing campaign. It is important to understand what your audience is interested in and what their needs are. Once you have this information, you can create content that will truly engage them. This could be information about new products or services, industry news, or tips and advice. Personalization can play a key role here; try incorporating the recipient’s name or using data to deliver content tailored to their browsing or purchasing history. Storytelling can also be a powerful engagement technique. A compelling story can evoke emotion and build a stronger connection between the brand and the customer.
Clear call to action (CTA)
A strong, clear call-to-action (CTA) is essential to improving your CTOR. The CTA should be easy to find and compelling enough to encourage the recipient to click. It can be a button or a text link, but it should stand out from the rest of the content. Play with colors, shapes, and sizes until you find the one that works best. The text within the CTA should also be action-oriented and provide a clear value proposition – remind the recipient what they’ll gain by clicking.
Optimized email design
The design of your email has a significant impact on how recipients interact with it. A visually appealing email, with a harmonious blend of images and text, can engage readers and make them more likely to click through. Use white space effectively to make your email content easy to digest. In addition, more people than ever are using their mobile devices to check their email. It’s critical that your emails are mobile-optimized and look as good on a small screen as they do on a desktop.
Segmented campaigns
Segmenting your email list allows you to send highly targeted emails that can significantly improve your CTR. You can segment your list based on a variety of criteria, such as demographics, purchase history, or engagement level. For example, long-time customers may appreciate exclusive offers or loyalty rewards, while new subscribers may benefit more from introductory guides or first-time purchase discounts. By tailoring content to specific segments, you make each email more relevant and increase the likelihood that recipients will click through.
Test and refine
Finally, never underestimate the power of testing to improve your CTR. A/B testing allows you to compare the performance of two different versions of an email to see which performs better. You can test virtually any element of your email, from subject lines to images to CTAs. Once you have the results, you can refine your emails based on what works best. Remember that testing is an ongoing process – customer preferences can change over time, so it’s important to keep testing and refining your strategy.
Examples of use
Product Launch Campaign
- Scenario: An ecommerce store launching a new product line notices a higher CTOR for emails showcasing the new products with user testimonials and a limited-time discount.
- Use Case Application: The brand can further harness this strategy for subsequent launches, emphasizing user testimonials and time-sensitive offers to drive engagement and clicks.
Content-Driven Strategy
- Scenario: A blogging platform observes a spike in CTOR when they share “top 10” type content or curated lists in their newsletters.
- Use Case Application: The platform can prioritize creating and sharing more of such content, possibly even segmenting its audience based on content preferences, ensuring higher engagement and CTOR.
Feedback Loop Initiative
- Scenario: A software-as-a-service (SaaS) company sends out emails to gather user feedback on a new feature update. They find that emails with interactive surveys embedded within them have a higher CTOR compared to those with external links to survey forms.
- Use Case Application: The company realizes that reducing the steps to participation by using embedded surveys can increase interaction and feedback rates. In future communications, they focus on providing more embedded interactive content to encourage immediate engagement.
Event Promotion Drive
- Scenario: An event management firm promotes various events through email campaigns. They notice a higher CTOR for emails that include teaser videos of the event or past event highlights.
- Use Case Application: The firm decides to include more multimedia content, especially short engaging videos, in their promotional emails. This strategy not only showcases the allure of the event but also provides recipients a visual stimulus, thereby increasing the chances of them seeking more information or buying tickets.
Loyalty Rewards Push
- Scenario: A retail chain with a loyalty program sends out emails to its members about redeeming their loyalty points. They observe that emails which showcase potential products or services members can get with their points have a higher CTOR than generic reminder emails.
- Use Case Application: To maximize engagement and point redemption (which often leads to further purchases), the retail chain begins to tailor their emails to individual member preferences, showing them specific items they are close to affording with their current loyalty points.

Limitations of using Click Through Open Rate
While the Click Through Open Rate (CTOR) is a valuable metric for understanding email engagement, it has its limitations when used in business analysis:
- Not a Direct Indicator of Sales or Conversions: While CTOR can show you how engaging your email content is, it doesn’t directly correlate with sales or conversions. A person might click on a link in an email but not complete a purchase or desired action on the website.
- Dependent on Email Content: CTOR might be affected by factors unrelated to the recipient’s interest in the product or service. For example, a catchy email headline or engaging content might lead to a higher CTOR, but that doesn’t necessarily mean recipients are interested in purchasing.
- Can Be Misleading with Low Open Rates: A high CTOR combined with a low open rate might give a skewed perception of success. If only a small percentage of recipients open the email, but a large portion of those click a link, the CTOR will be high. However, this might not represent a broad-based interest among the entire email list.
- Doesn’t Account for Multiple Clicks: CTOR doesn’t differentiate between a user who clicked once and a user who clicked multiple times. Thus, it might not capture the depth of engagement within the email.
- Subject to External Influences: CTOR can be influenced by external factors like holidays, promotions, or current events that might spike interest temporarily but don’t indicate a lasting trend.
- Limited by Email Design and Structure: If an email is poorly designed or the links aren’t clearly visible, it can result in a lower CTOR. In such cases, CTOR is reflecting design flaws rather than lack of interest in the content.
- Overemphasis Can Neglect Other Important Metrics: Focusing too much on optimizing for CTOR might lead businesses to neglect other crucial metrics like conversion rates, average order value, and customer retention.
- Not Always Comparable Across Different Campaigns or Industries: What’s considered a good CTOR can vary based on the type of email (e.g., newsletter vs. promotional) or industry standards. Directly comparing CTORs without context can be misleading.
In conclusion, while CTOR is a valuable metric in the arsenal of email marketing KPIs, it should be used in conjunction with other metrics and not be the sole determinant in evaluating the success of an email campaign.
KPIs and metrics relevant to Click Through Open Rate
- Open Rate: Measures the percentage of recipients who opened the email. A discrepancy between a high open rate and a low CTOR can hint at content or design issues within the email.
- Bounce Rate: Represents the percentage of emails that couldn’t be delivered. A high bounce rate can negatively affect deliverability and subsequently, CTOR.
- Unsubscribe Rate: Monitors the percentage of recipients who opted out of your email list. If CTOR is low and the unsubscribe rate is high, it’s an immediate red flag.
- Conversion Rate: The percentage of email recipients who clicked on a link within an email and completed a desired action, such as making a purchase.
Understanding and improving CTOR in tandem with these metrics can guide businesses in crafting more impactful email marketing campaigns.
