Let’s be honest: when we talk about email marketing, we often think about the subject line, design, the header, or even the famous CTA. But statistics? They’re sometimes pushed into the background… until the moment you ask, “But did someone really read this email?”
This is where an analysis of open rates, clicks, bounce rates, or even unsubscribes begins. These key indicators reveal a lot about how responsive your recipients are, the quality of your content, the relevance of your messages, and even the deliverability of your emails.
I’ll give you the keys to decode the results you should watch and how to use data to improve your next sends.
Tracking your email marketing statistics is essential
Point to note: email statistics can be controversial due to bots, tools that analyze them, or even your own calculation methods.
In short, you may not get the same results from the same email campaigns if you change tools and/or analysts. The best approach is therefore to compare by period! That ensures tracking under the same conditions, which is essential.
Next, the KPIs that deserve your attention are often similar across marketing teams. Do your contacts open your messages? Do they click? Do they unsubscribe? Each number helps you understand what engages—or doesn’t—your contacts.
Without these indicators, it’s difficult to identify areas for improvement, validate what works, or justify your choices to your team. Analyzing your results means laying the foundation for an agile email strategy—one that evolves with your audience and adapts to the signals.
The indicators you absolutely must track in your email campaigns
Having access to statistics is good. Knowing which ones to analyze to improve your campaigns is better. Not all indicators are equal, and some clearly deserve more attention than others.
The open rate is often the first instinct. It gives you an indication of the effectiveness of the subject line, the sender’s reputation, and the timing of the send. Be careful, though: this KPI can be skewed by automatically recorded opens. It’s still useful for comparing different approaches in similar campaigns.
Next comes the click-through rate (CTR), which measures the real engagement of your recipients. It can be expressed as raw clicks (all clicks) or unique clicks (one click per contact). The second indicator is generally more reliable for assessing how attractive your content is and the effectiveness of your calls to action.
To refine your analysis, the response rate (or click-to-open rate) relates clicks to opens. It helps you understand, among those who opened your email, how many actually engaged. It’s a good indicator of the relevance of the content once it’s been read.
The conversion rate is without a doubt the most strategic KPI. It measures the achievement of your end goals: booking a meeting, requesting a demo, purchase, downloading, etc. It gives you a clear view of the return on investment of your campaigns.
Some indicators can also serve as alerts. An increase in the unsubscribe rate may reflect a problem with frequency, targeting, or the perceived value in your content. The bounce rate (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 isn’t limited to filling out a dashboard. It’s 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 inevitably comes up: “Are my results good?”
It’s hard to assess the performance of your email campaigns without a point of comparison. Several studies, such as those by Tabular, GetResponse, Statista, or even our internal data, give you a broad overview.
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 industry email statistics sheet.
These figures remain overall averages. They vary greatly depending on the industry, the audience (B2B or B2C), the type of campaign, and 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 standard newsletter, with performance often multiplied.
What matters isn’t reaching an ideal average, but evaluating your results within a range that makes sense for your activity. And above all, measuring your progress over time. A significant gap can reveal a weakness to fix… or a good practice to strengthen. ?
How to use statistics to improve your campaigns
Knowing the right indicators and reference benchmarks is a first step. But to truly improve, you also need to know how to analyze this data… and turn it into an optimization lever. Marketing automation tools have their own nuances to understand.
Start by comparing your results to your industry’s averages. A 2% click rate may be very satisfying in some industries and insufficient in others. The goal isn’t to hit an absolute number, but to position your performance within a reasonable order of magnitude for your business.
Then, adjust your objectives based on your field. If you’re B2B in the software industry, your open rates won’t be the same as those in consumer e-commerce. Your indicators should 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 in your click-through rates… and your conversions.
