Email Marketing Metrics That Matter for SEO and How to Improve Them

It is 2025, and email marketing continues to be one of the strongest marketing tactics. While some marketers think sending bulk emails does the job, the smart ones carefully plan each email to drive maximum output. Your customers' inboxes are flooded with hundreds of emails every day. You might not want to end up in a spam folder by sending random, generic messages.  

So, how do you know if your strategy is hitting or missing the bull's eye? Email engagement metrics will tell you the real story. Let's see what those metrics are and learn some tips on optimizing email campaigns for better SEO. 

What are Email Marketing Metrics?  

In simple words, email marketing metrics are key performance indicators that measure the success of an email campaign.  

These metrics can track audience interaction, delivery success, and overall effectiveness. So, they inform you how well your email campaign performs. Understanding these metrics can significantly improve your email marketing efforts and, indirectly, your SEO.  

SEO Impact of Email Marketing 

Although email campaigns and SEO are two separate concepts, they can be combined to complement each other. For instance, emails can route traffic to your website, boost website engagement, and increase dwell time. Such passive impact on user behavior can contribute to search engine rankings and establish emails as a valuable tool beyond direct communication. 

Importance of Tracking Email Marketing Metrics for SEO 

Sending emails without tracking and analyzing email marketing metrics for SEO is like shooting in the dark; you will not know what is helping and what is a waste of time. While you might see a surge in website visitors and even sales, you cannot confidently claim it is due to your email campaigns. So, tracking is essential for truly understanding how your audience behaves and engages with your messages. 

When you first launch an email campaign, all you know is that subscribers are interested in what you have to offer. It is like fishing — but without knowing which bait works better, you cannot refine your approach. Analyzing metrics like open rates, click-through rates, and conversions helps build a clearer picture of their preferences. 

Performance tracking can let you tailor content, subject lines, and offers to match audience behavior. For example, you may find out that short subject lines drive more engagement, or discount codes might lead to higher conversions. 

How to Optimize Email Campaigns for Better SEO and Overall Performance? 

There are tons of elements that you can track and analyze for your email marketing campaign. Let's talk about the ones that are important to assess the flow of traffic towards your website and how to cater to them. 

Improving Email Click-through Rate for SEO 

Email click-through rate is one of the prime metrics for gauging the success of your strategy. The importance of email click-through rate for SEO is evident from the fact that it literally represents the number of people who clicked one or more links in your email.  

If you sent out 10,000 delivered emails that gained 500 clicks, your click-through rate is 5%. All you must do is divide the clicks obtained by the number of delivered emails and multiply the answer by 100. 

Pro Tips: Try experimenting with different design formats, such as an inverted triangle design that directs the viewer's attention to the CTA button. Moreover, your clicks will improve if you present clear, relevant, and valuable information through personalization and email list segmentation. 

Analyzing Click to Open Rate (CTOR) 

A click-to-open rate tells you how many people who open your emails go ahead to click. Since CTR is calculated based on the total number of delivered emails, its performance can be skewed by the open rates. The click-to-open rate eliminates that variable and shows if the email content effectively prompted those who opened it to click on a link.  

Pro Tips: Start by crafting engaging content above the fold, especially compelling headlines. You might also want to optimize your email design for both mobile and desktop. Moreover, regular A/B testing of CTA placements will help you pinpoint the most fruitful strategies for boosting engagement. 

Email Conversion Rate Optimization 

Email conversion rate is the percentage of email subscribers who took your desired action, which, in this case, is going to the website and purchasing something. It is a key metric to judge the quality of your email content and the effectiveness of your CTAs.  

Pro Tip: Let's suppose you want your viewers to go to your website and sign up for a service. In this case, email conversion rate optimization will require you to examine surrounding metrics, like open rates or clicks, that can pinpoint the exact issues with your email copy. Once identified, you can A/B test each element for better conversion rates. 

Don’t Overlook Forward and Share Rates 

Most marketers assume the rate at which people share or share their emails does not do much. If you think about it, it is one of the most important metrics, especially if your goal is SEO and website ranking.  

It helps you generate new contacts and attract new leads that can become your active visitors.  

Pro Tip: Of course, amazing content will make your existing subscribers forward it. You can even share an incentive to your readers to share your newsletter with their friends. For instance, offer free shipping or a discount code for those who get others to subscribe to your emails. 

Identify Your Email Delivery Rates 

While most email marketers rely on email marketing automation these days, they forget to check if their emails actually landed in peoples' inboxes. The email delivery rate tells you the number of emails that did not bounce. It is not the same as email deliverability, but it is a hard metric that indicates when your deliverability is suffering. 

Pro Tip: To improve your email delivery rate, you must go through the bounce report and identify the issues. Typically, bounces occur due to typos, spam reports, duplicate emails, missing subject lines, or invalid unsubscribe headers. Once you identify your specific cause, refine your sending practices to ensure your message reaches the maximum number of people. 

Enhance Email Engagement  

Email engagement rate is a contact-based metric that measures a subscriber's interaction across multiple campaigns. Unlike campaign-specific metrics, engagement rate provides a broader view of subscriber behavior. By tracking this metric, email marketers can isolate inactive users from active users for email list cleaning or segmentation.  

Pro Tip: You can leverage a subscriber's engagement behavior to improve your targeting strategies. Through email marketing automation, you can send out specific emails triggered when a subscriber has been inactive or changes their interaction pattern. As a result, you will enjoy consistent engagement and the overall success of your email campaign. 

Final Word 

It is crucial to remember that the campaign's performance isn't only about the email itself but the bigger picture. Each email metric provides insights into different aspects, like subscriber growth or email engagement. The choice of the right metrics depends on your client's goals. 

For example, a brand awareness campaign will be successful with high open rates, even if the click rates are low. On the other hand, you might want to see high click-through rates if your goal is to leverage the SEO impact of email marketing. 

While it is good to track all metrics, there must be some hero metrics that serve as key performance indicators (KPIs). It helps avoid data clutter and vague results.
