These insights empower marketers to refine strategies, better segment their audience, and tailor content for improved recipient engagement.

By reading this blog, you will learn about the foundational principles of email analytics and the 20 essential metrics you should measure to enhance the effectiveness of your email campaigns.

What is Email Analytics?

Email Analytics

Email analytics is the process of using data and metrics derived from email marketing campaigns to understand how recipients engage with emails. It involves tracking various metrics like open rates, click-through rates, conversions, and other engagement indicators.

These insights help marketers comprehend audience behaviors, preferred content, and areas for improvement in their email strategies, leading to more engaging and effective communication.

Why is Email Analytics Important?

Understanding your audience is crucial in any marketing strategy. It can help you in the following ways:

1. Insight into Audience Behavior

Beyond just open rates and click-throughs, email analytics can track the time spent reading an email, the device used, and even the specific sections of the email that received the most attention. This granular data reveals not just actions but also user habits and preferences, enabling better personalization.

2. Campaign Assessment

Email analytics isn’t just about the success rate; it dissects the performance, pinpointing which elements attract the most attention. For example, it might reveal that a particular CTA drove higher conversion rates or that a specific design format led to increased engagement.

3. Content Relevance

Analytics offers content heat maps, revealing areas that caught readers’ attention or caused them to lose interest. This in-depth analysis helps in creating focused, compelling content and subject lines that cater to the audience’s preferences and behaviors.

4. Opportunities for Improvement

It’s not just about identifying low-performing areas; it’s about learning why they underperformed. For instance, a low click-through rate may not just signal a weak CTA but could point to content quality, relevance, or layout issues.

5. Refining Segmentation

Analytics can assist in deeper audience segmentation, allowing marketers to group recipients based on engagement behavior. This means targeted campaigns catering to specific behaviors or preferences, resulting in higher response rates.

6. Strategy Enhancement

Continuous monitoring allows for constant learning and adaptation. Marketers can leverage this feedback loop to fine-tune future strategies, applying lessons from analytics for more impactful campaigns.

7. Optimizing Engagement

The ultimate goal is to enhance the audience’s interaction. Insights from email analytics can help in A/B testing different elements, ensuring campaigns are optimized for maximum engagement and, consequently, better performance.

20 Essential Metrics For Email Marketing You Should Track

Here are the 20 essential metrics for email marketing that you should track to measure the performance of your email marketing campaign.

1. Open Rate

Open Rate

The Open Rate is one of the most important email metrics that measures the percentage of recipients who opened an email. The formula for calculating the open rate in email marketing is:

Open Rate = (Number of Delivered Emails/ Number of Emails Opened​) × 100

This formula compares the number of emails opened to the total number of emails delivered. The result is expressed as a percentage, providing insights into the effectiveness of your email subject lines and overall campaign engagement. This metric assesses the appeal of subject lines and preheaders, highlighting email list quality and content relevance. Marketers fine-tune strategies for better engagement and impact by observing open rate trends.

2. Click-Through Rate (CTR)

Click-Through Rate (CTR)

Click-through rate (CTR) is the ratio/number of recipients who clicked on a link within an email to the total number of recipients. The formula for calculating the click-through rate (CTR) in email marketing is:

CTR = (Number of Delivered Emails/Number of Clicks​) × 100

This formula compares the number of clicks on links within an email to the total number of emails delivered. The resulting percentage indicates the effectiveness of your email in encouraging recipients to interact with the content and take further action.

This email marketing metric assesses the effectiveness of call-to-action (CTA) buttons and email content such as the subject line and the email body, helping marketers understand how to refine strategies for better interaction and engagement.

3. Conversion Rate

Conversion Rate

The Conversion Rate is a key metric that tracks the percentage of email recipients who complete a desired action after engaging with the email. Whether it’s making a purchase, signing up for a webinar, or downloading a resource, this metric showcases the effectiveness of your email campaign.

Conversion Rate = (Number of Clicks/Number of Conversions​) × 100

This formula compares the number of desired actions (conversions) to the total number of clicks generated by your email campaign. The result is expressed as a percentage, indicating the efficiency of your campaign in converting clicks into meaningful actions.

By evaluating this rate, you can understand the impact of your emails on driving the intended actions and identify elements contributing to success or areas needing improvement. Enhancing this rate involves optimizing content, design, and targeting strategies to encourage more recipients to take the desired actions, ultimately boosting overall campaign performance.

4. Bounce Rate

Bounce Rate

The Bounce Rate measures the percentage of emails that were not delivered to recipients’ inboxes. It comprises both soft bounces, typically temporary issues like a full inbox, and hard bounces, indicating permanent problems like an invalid email address.

Bounce Rate = (Total number of bounced emails ÷ Total number of emails sent) x 100

The Bounce Rate is calculated by dividing the total number of bounced emails by the total number of emails sent and then multiplying the result by 100 to get the percentage. A higher bounce rate might suggest issues with list quality or email hygiene, urging a review of contact lists, rectifying incorrect email addresses, and maintaining list hygiene for improved email deliverability.

5. List Growth Rate

The List Growth Rate measures how your email list expands over a specific period, usually monthly. The formula for calculating the List Growth Rate in email marketing is:

List Growth Rate = ([(New Subscribers – Unsubscribes) / Initial List Size] \times100​) ÷ Initial List Size

This formula takes into account the changes in the size of your email subscriber list over a specific period. It considers new subscribers gained, subtracts any unsubscribes, and expresses the net growth as a percentage of the initial list size. This metric provides insights into the health and expansion of your email subscriber base.

A positive growth rate signifies healthy list expansion, influenced by successful campaigns, content strategies, and acquisition tactics. Sustained negative growth could indicate issues in list maintenance, campaign relevancy, or subscriber disengagement. Understanding this metric helps tailor strategies for audience retention, content enhancement, and effective audience acquisition for optimal list expansion.

6. Forward Rate

Forward Rate

The Forward Rate is an essential email metric for gauging audience engagement and content resonance. The formula for calculating the Forward Rate in email marketing is:

Forward Rate = (Number of Delivered Emails/Number of Email Forwards​) × 100

This formula measures the number of times an email is forwarded to others, compared to the total number of delivered emails. It is expressed as a percentage, providing insights into how engaging and shareable your email content is among your audience, showcasing the potential reach beyond your initial subscriber list.

A higher forward rate showcases content appreciation and is a testament to the virality and relevance of your emails. Analyzing this rate provides insights into the impact and appeal of your content, guiding future strategies to capitalize on audience preferences and drive further engagement.

7. Unsubscribe Rate

Unsubscribe Rate

The Unsubscribe Rate measures the percentage of subscribers opting out of your email list after receiving an email campaign. It reflects the audience’s disengagement or dissatisfaction with the content received, the frequency of emails, or both. Although a high unsubscribe rate might seem discouraging, it offers essential feedback. The formula to calculate the Unsubscribe Rate is:

Unsubscribe Rate = (Number of Unsubscribes ÷ Total Emails Delivered) x 100

It is calculated by dividing the total number of unsubscribes by the total number of emails delivered (minus any bounces) and then multiplying the result by 100 to get the percentage. Analyzing the reasons behind these exits aids in refining content, frequency, and targeting strategies. It provides an opportunity to reevaluate the email marketing approach and tailor content to suit the audience better, reducing further attrition and increasing engagement with those who remain subscribed.

8. Spam Complaint Rate

Spam Complaint Rate

The Spam Complaint Rate measures the number of recipients who mark your email as spam, indicating dissatisfaction with the content or frequency. It’s crucial because a high spam complaints rate can affect your sender’s reputation and email deliverability.

Spam Complaint Rate = (Number of Delivered Emails/Number of Spam Complaints​) × 100

This formula measures the ratio of reported spam complaints to the total number of delivered emails, expressing the result as a percentage. Monitoring the Spam Complaint Rate helps in gauging the quality of your email content, sender reputation, and overall email deliverability.

Importantly, it provides insight into what aspects of your emails might be displeasing the audience, enabling improvements in content, targeting, or sending frequency. Keeping this rate low is crucial to maintaining a positive sender reputation, better engagement, and preventing the emails from ending up in spam folders, ensuring emails reach the intended audience’s inbox.

9. List Churn Rate

List Churn Rate

List Churn Rate measures the rate at which subscribers opt-out or leave your email list over a specified period. The formula for calculating the List Churn Rate in email marketing is:

List Churn Rate =(Total Number of Contacts/Number of Unsubscribes + Email Bounces​)×100

This formula measures the rate at which your email list decreases due to unsubscribes and email bounces, expressed as a percentage of the total number of contacts or subscribers. High churn rates might suggest irrelevant content, high frequency, or unsuitable targeting.

By focusing on more engaging content, providing value, managing email frequency, and improving segmentation, you can reduce the churn rate and retain more subscribers. Monitoring the List Churn Rate is crucial as it reflects the attrition or loss of contacts from your email list, indicating the health and sustainability of your subscriber base over time.

10. Email Sharing/Forwarding Rate

Email Sharing/Forwarding Rate

Email Sharing/Forwarding Rate signifies the number of times an email is shared or forwarded by recipients. The formula for calculating the Email Sharing/Forwarding Rate in email marketing is:

Email Sharing/Forwarding Rate = (Number of OpensNumber of Email Shares/Forwards​)× 100

This formula measures the percentage of opened emails that are subsequently shared or forwarded by recipients. It helps in understanding the engagement level and the willingness of your audience to pass along your email content to others, indicating the virality and potential reach beyond your initial email recipients.

High sharing rates indicate content relevance, engagement, and resonance with your audience. By encouraging and fostering content that people find valuable and shareable, you can enhance your brand visibility and broaden your audience through organic reach, harnessing the power of your subscribers as brand ambassadors.

11. Email List Segmentation Effectiveness

Email List Segmentation Effectiveness assesses the success of dividing your subscriber base into distinct segments based on various attributes. This metric measures the relevance and response rate of emails within each segmented group. It allows you to understand how effectively tailored content aligns with the unique preferences of different segments.

A higher effectiveness indicates that your segmentation strategies are resonating well, resulting in increased open and click rates. It also helps in identifying where improvements in content personalization are required to ensure that the right message reaches the right audience, optimizing engagement and conversions.

12. Engagement Over Time

Engagement Over Time evaluates how recipient engagement evolves throughout your email campaign’s duration. The formula for calculating Engagement Over Time involves assessing the average engagement metrics, such as open rates, click-through rates, or conversions, during specific periods. It can be calculated as:

Engagement Over Time =(Total Engagement for a Time Period ÷ Number of Emails Sent or Delivered in the Same Period

This formula helps to evaluate the average engagement metrics (like opens, clicks, or conversions) over a particular timeframe, allowing you to track and compare the engagement trends and performance of your email marketing campaigns over different periods.

By tracking this metric, you assess how subscribers interact with your emails over a specified period, spotting trends, peak engagement moments, and declines. It provides insights into when your audience is most responsive and when they disengage.

13. Mobile Open Rate

Mobile Open Rate

Mobile Open Rate signifies the percentage of emails opened on mobile devices compared to desktops. With the surge in mobile usage, analyzing this metric is crucial for understanding how recipients access your emails. The formula for calculating the Mobile Open Rate in email marketing is:

Mobile Open Rate = (Number of Opens on Mobile Devices/ Total Number of Opens)×100

This formula measures the percentage of email opens that occur on mobile devices compared to the total number of email opens. It helps in understanding the proportion of your audience accessing and engaging with your emails on mobile devices, which is crucial for optimizing email design and content for mobile users. A higher mobile open rate suggests the importance of mobile-friendly content and design.

It directs you to optimize emails for mobile devices, ensuring they display properly and are easy to navigate on smaller screens. Tailoring content for mobile consumption improves user experience, positively impacting engagement and conversions. Understanding this rate helps fine-tune your strategies for the evolving landscape of email accessibility.

14. Click-to-Open Rate (CTOR)

Click-to-Open Rate (CTOR)

Click-to-Open Rate (CTOR) is a pivotal metric revealing the engagement quality within an email. It calculates the percentage of unique opens that resulted in a click on any given link or element within the email. Unlike the Click-Through Rate (CTR), CTOR measures click only concerning the number of opened emails, offering a more concentrated understanding of the email’s effectiveness.

The formula for calculating the Click-to-Open Rate (CTOR) in email marketing is: CTOR=(Number of Clicks/Number of Opens)×100

This formula measures the percentage of email recipients who opened an email and subsequently clicked on a link within that email. It focuses specifically on the engagement of those who opened the email, giving insight into the effectiveness of the content and calls to action within the email for the engaged audience.

A higher CTOR signifies that the content resonated with the reader, driving a higher interaction per open. It’s a vital gauge for email content relevance, allowing refinements to optimize future email campaigns.

15. Subscriber Lifetime Value

Subscriber Lifetime Value gauges the long-term value derived from an email subscriber. It’s a comprehensive metric analyzing the net benefit a subscriber brings to a business over their engagement duration. The formula for calculating Subscriber Lifetime Value (SLV) involves several variables and might vary based on specific business models. However, a common formula used to estimate Subscriber Lifetime Value is:

Subscriber Lifetime Value = Average Monthly Revenue per Subscriber× Average Lifespan of a Subscriber

This calculation involves determining the average revenue generated per subscriber each month and multiplying it by the average duration or lifespan of a subscriber in months. The result represents an estimation of the total revenue or value generated by a subscriber over their entire engagement period with your business or service

A higher SLV demonstrates active, engaged, and lucrative subscribers, allowing businesses to tailor marketing strategies, segment effectively, and nurture high-value relationships. This metric ensures the optimization of marketing efforts and investment in subscribers with the most substantial long-term value.

16. Overall ROI

Overall ROI

The overall Return on Investment (ROI) metric for email marketing measures the profitability of your email campaigns by comparing the gains against the costs associated with running those campaigns.

The formula to calculate the overall ROI for email marketing is:

ROI = (Net Profit from Campaign − Cost of Campaign​ /Cost of Campaign) × 100

This formula takes into account the net profit generated from the campaign (revenue earned minus expenses) and divides it by the cost of the campaign. The result is expressed as a percentage, indicating the return on investment for the specific email marketing effort. A positive ROI signifies that the campaign generated more revenue than the cost to run it, while a negative ROI indicates a loss.

17. Geographic Data

Geographic Data refers to insights gathered about a subscriber’s location, providing a nuanced understanding of their geographical spread. It’s an invaluable metric for tailoring campaigns to resonate with regional specifics, addressing cultural or timing relevance. By analyzing this data, marketers refine content strategies, adjusting promotions, language, or timing to cater to diverse audiences.

Understanding where subscribers are concentrated assists in personalized targeting, ensuring relevance and resonating content to engage a broader audience. This detailed geographical insight enables the tailoring of campaigns and communication to better connect with audiences across varied locations.

18. Device Metrics

Device Metrics offers valuable insights into how subscribers engage with emails across various devices, spanning mobile, desktop, or tablet. This metric divulges which devices are predominantly used to open emails, the corresponding engagement rates, and how these users interact with the content. This data aids in optimizing email layouts and designs for different screens, enhancing user experience.

Insights into device preferences allow marketers to tailor content for specific device formats, ensuring better readability and interaction across diverse platforms, and ultimately improving overall email engagement and performance.

19. Social Media Metrics

Social Media Metrics

Social Media Metrics gauge the impact and reach of your email campaigns on social platforms. Tracking how subscribers engage with your emails on social media—like sharing, comments, or likes—provides a deeper understanding of how content resonates beyond the email platform. It measures the virality and amplification of your email content when shared on social channels.

Insights from these metrics can guide strategies for cross-channel integration, helping in optimizing content that garners more social interaction, and extending the email’s reach and influence across various social media platforms.

20. Revenue Per Email

Revenue Per Email

Revenue Per Email is a crucial metric that signifies the direct impact of your email marketing on generating revenue. It calculates the monetary value each email contributes to your overall revenue. By measuring the income generated per email sent, you can understand the financial effectiveness of your campaigns. The formula to calculate Revenue Per Email (RPE) is:

The formula to calculate Revenue Per Email (RPE) = (Total Revenue Generated/ Number of Emails Sent​)

This formula helps measure the average revenue generated by each email sent in an email marketing campaign. By dividing the total revenue generated by the number of emails sent, you get an insight into the effectiveness of your email campaigns in driving revenue. A higher RPE indicates that each email sent is generating more revenue, showcasing the campaign’s efficiency in converting email communication into monetary returns.

Tracking these 20 email marketing metrics provides a holistic view of your campaigns, enabling data-driven decisions and continual improvement of your email marketing efforts.
