Let’s be honest: when we talk about email marketing, we often think about the subject line, the design, the header, or even the famous CTA. But statistics? They are sometimes pushed into the background… until the moment when we ask ourselves, “But actually, did anyone really read this email?”
That is the beginning of an analysis of open rates, click rates, bounce rates, and even unsubscribe rates. These are all key indicators that say a lot about the responsiveness of your recipients, the quality of your content, the relevance of your messages, and even the deliverability of your emails.
I’ll give you the keys to deciphering the results you need to monitor and how to use data to improve your next sends.
Tracking your email marketing statistics is essential
One thing to keep in mind: email statistics can be controversial because of bots, analysis tools, or even your own calculation methods.
In short, you may not get the same results from running the same email campaigns if you change tools and/or analysts. So the best thing to do is compare by period! That ensures tracking under the same conditions, and that is essential.
Then, the KPIs that deserve your attention are often similar across marketing teams. Do your contacts open your messages? Do they click? Do they unsubscribe? Every figure helps you understand what engages your contacts, or not.
Without these indicators, it is difficult to identify areas for improvement, validate what works, or justify your choices to your team. Analyzing your results means laying the foundations for an agile email strategy, one that evolves with your audience and adapts to signals.
The indicators you absolutely need to track in your email campaigns
Having access to statistics is good. Knowing which ones to analyze to improve your campaigns is even better. Not all indicators are equal, and some clearly deserve more attention than others.
The open rate is often the first reflex. It gives you an indication of the effectiveness of the subject line, sender recognition, and send timing. Be careful, however: this KPI can be skewed by automatically recorded opens. It is still useful for comparing different approaches across similar campaigns.
Next comes the click-through rate (CTR), which measures the real engagement of your recipients. It can be expressed as total clicks (all clicks) or unique clicks (only one click per contact). This second indicator is generally more reliable for assessing the attractiveness of your content and the effectiveness of your calls to action.
To refine your analysis, the click-to-open rate links clicks to opens. It tells you, among those who opened your email, how many actually interacted. It is a good indicator of the relevance of the content once it has been read.
The conversion rate is probably the most strategic KPI. It measures whether you achieved your final objectives: booking an appointment, requesting a demo, making a purchase, downloading, etc. It gives you a clear view of the return on investment of your campaigns.
Some indicators can also serve as warnings. A rise in the unsubscribe rate may reflect a problem with frequency, targeting, or the perceived value of your content. The bounce rate, especially hard bounces, directly affects your deliverability. Poor list hygiene can impact your sender reputation and reduce the overall effectiveness of your sends.
Tracking your KPIs is not just about filling a dashboard. It is what allows you to make informed decisions, adjust your strategy, and continuously optimize your campaigns for better results.
What do the 2025 email marketing benchmarks say?
Now that you know what to analyze, one question naturally arises: “Are my results good?”
It is difficult to assess the performance of your email campaigns without a benchmark. Several studies, such as those from Tabular, GetResponse, Statista, as well as our internal data, give you an overall view.
In 2025, the average rates observed are around 27 to 32% for opens, between 2 and 3.5% for clicks, with an unsubscribe rate generally stable at around 0.1%. The conversion rate, meanwhile, varies by industry, but is often between 2 and 6.5%. You can download our email statistics sheet by industry.
These figures remain overall averages. They vary greatly depending on the industry, the target audience (B2B or B2C), the type of campaign, or the sending volume. For example, an automated email such as an abandoned cart or a welcome message can achieve open rates far higher than those of a traditional newsletter, with performance often multiplied.
What matters is not reaching an ideal average, but evaluating your results within a range that is consistent with your business. And above all, measuring your changes over time. A significant gap may reveal a weakness to correct… or a good practice to strengthen. ?
How to use statistics to improve your campaigns
Knowing the right indicators and the benchmark references is a first step. But to really improve, you still need to know how to analyze this data… and turn it into a lever for optimization. Marketing automation tools have subtleties that need to be understood.
Start by comparing your results with the averages in your industry. A 2% click-through rate can be very satisfactory in some industries, and insufficient in others. The goal is not to reach an absolute figure, but to place your performance within an order of magnitude that is consistent with your business.
Then, adjust your objectives according to your field. If you are in B2B in the software sector, your open rates will not be the same as those in mass-market e-commerce. Your indicators must reflect the reality of your audience and your campaigns.
Use this data as a tool to continuously improve your messages. Work on your email subject lines to generate more interest. Segment your lists further to send truly targeted messages. Test different sending times, different formats, and refine your content. These are often simple adjustments, but they can make all the difference to your click-through rates… and your conversions.
Conclusion
