Cold emails remain one of the most cost-effective strategies for generating leads and driving sales. Especially when done smartly. But how do you know if your approach is right? Are your metrics actually good, or could they be better?

In this guide, we’ll break down the latest cold email statistics for 2025, so you can compare your performance with existing benchmarks. Learn the average response rate for cold emails, what open rate is good for your industry, and other stats to measure your success and grow faster.

General cold email statistics

Let’s look at the state of cold email in 2025:

1. In B2B, about 61% of decision-makers prefer email as the primary channel for outreach. 
2. 37% of decision-makers receive more than 10 emails per week.
3. However, 20% claim none of them are relevant. 
4. 73% of decision-makers claim personalization matters for cold outreach.

As for B2C, you’ll hardly find true stats. Most statistics refer to newsletters, marketing drip, and other permission-based campaigns rather than the cold outreach itself. 

This issue lies within strict compliance boundaries. Sending cold emails to individual consumers is heavily restricted by laws like CAN-SPAM and GDPR. That’s why most B2C campaigns are targeted at people who’ve already opted in.

Anyway, some findings can be found. According to the Emailtooltester report:

5. 38% of surveyed consumers prefer companies to contact them by email.
6. On average, people receive 15 cold emails per week.
7. 51.4% of them come from companies in the health and beauty industry.
8. 44.7% of the surveyed consumers consider messages to be trustworthy, while 36.2% of respondents don’t trust them at all.

Cold email open rate statistics in 2025 

The open rate is the first sign of how your campaigns perform. This metric shows whether your message reaches the right people and sparks their interest. Looking into the relevant cold email stats may provide valuable insights on how to improve your subject lines, sender reputation, and overall targeting strategy.

Average cold email open rate (B2B vs B2C)

The latest B2B cold outreach stats reveal:

9. The average cold email open rate for B2B across all industries is 27.7%.

Due to better personalization and sender authorization practices, this metric has increased over the last years. In 2019, for instance, the average open rate for cold emails was only 16.6%. 

10. The average cold email open rate among C-level executives is 28.1%.
11. For non-C-level executives, this rate is 27.3%.

For B2C, according to Emailtotester’s report:

12. 51.4% of them come from companies in the health and beauty industry.
13. 44.7% of the surveyed consumers consider messages to be trustworthy, while 36.2% of respondents don’t trust them at all.

What is a good open rate for cold emails?

According to Belkin’s recent report

14. In general,  a good open rate for cold emails in 2025 is considered to be above 45%. 
15. Businesses operating in the software industry have the highest open rates – 47.1%.
16. The lowest average open rates are shown by companies in the consumer goods (19.3%) and banking (19.7%) industries.

Below are cold email benchmarks for various industries that you can take as a reference point; aim for higher metrics to show strong performance.

Cold email subject line statistics

Subject lines directly influence whether your email will be opened or not. Here is what numbers tell us about their impact on open rates:

17. According to Zippia’s research, approximately 64% of people make a decision to open an email based on a subject line, while  33% of recipients will do it if the subject line is catchy.
18. Zerobounce provides a bit higher percentage: 43% of people will engage with a message that has an attention-grabbing subject line.
19. Interestingly, based on Mailchimp’s study, subject lines that include both recipients’ first and last names influence open rate most positively (33%).
20. Using just last names in subject lines brings a 17% open rate.
21. Using only first names in subject lines generates only a 9% open rate.
22. According to a study conducted by Yesware, subject lines that include numbers generate 45% higher open rates.
23. Subject lines framed as questions may bring you a 10% higher open rate.

We can clearly see that questions spark more interest in recipients.

What about salutations in subject lines?

24. Generic greetings, such as “Hello” or “Friend”, used in subject lines can lower open rates to 9%.
25. As is stated in Belkin’s report, subject lines that are three, seven, or eight words long show the highest open rates (33%).
26. Surprisingly, subject lines in uppercase have the highest open rates of 35%, while subject lines in Sentence case show an open rate of 24%.

🤔 How to find out which subject lines work best in YOUR campaigns?

Identify the most effective subject lines with the Snov.io A/B testing feature. You can include up to 15 variations to each step of your campaigns, so don’t limit yourself.

Experiment with subject line length, style, case, CTA, wording, or any other idea you have to see what drives opens in your niche.

Cold email response rate statistics in 2025

The response rate indicates whether your recipient is interested in the content of your message. But what is a good reply rate for cold email? Let’s review relevant emailing statistics and industry benchmarks to figure it out. 

The average reply rate for cold email

The average email response rate is lower than the open rate. According to Belkin’s report:

27. The average response rate for cold emails is 5.1%. 
28. The average cold email response rate for C-level professionals is 4.2%, while for non-C-level executives, it is 5.6%.
29. Emails to HR specialists show the highest reply rate of 8.5%.
30. Sequences sent to fewer than 100 recipients drive the highest reply rate, up to 5.5%.

But what response rate truly counts as “high”?

What is a good response rate for cold email in 2025?

Considering cold email benchmarks mentioned above:

31.  A truly good cold email reply rate in 2025 is 10%. 
32. Legal services companies have the highest response rate across industries, up to 10%.
33. Businesses operating in the software sector show the lowest response rates (less than 1%).

But keep in mind that this is a general score, not tied to any specific industry. B2B cold email response rates depend on the niche and the target recipients. So don’t be discouraged if your results are slightly lower. Take benchmarks for various industries as a reference point and aim for higher open rates:

However, if you’re seeing a response rate lower than 5%, it may be a sign that your campaign needs optimization.

Now, let’s move on to the conversion rate.

Cold email conversion rate statistics in 2025 

The ultimate sales goal isn’t high reply rates — it’s conversions. And not every reply is equal to a conversion. So, first, let’s define what can be considered a conversion in cold outreach, and then dive into key emailing statistics.

What is a conversion in cold emailing (reply, meeting booked, etc.)?

Typically, a conversion means that your recipient took a desired action. This can be a booked meeting, a positive reply (or any reply at all), a purchase, signing up for a trial, and so on. 

Average cold email conversion rate

According to recent Focus Digital research:

34. The average conversion rate for cold emails is 0.2153%. 
35. This conversion rate means that one deal is secured for every 464 emails sent.
36. Personalization can improve this metric by 10%. 

Again, to find your optima, refer to the average cold email conversion rate benchmarks, which differ from industry to industry:

How to improve your cold email metrics: tips and tools from Snov.io

Now that you know cold email statistics and key benchmarks, let’s explore how to improve your results. Here are practical tips to optimize your campaigns:

Improve deliverability 

How can prospects reply if your campaigns never reach their inboxes? Focusing on inbox placement should be step number one. Before starting cold outreach, set up proper authentication (SPF, DKIM, DMARC) and utilize warm-up tools to establish a strong sender reputation. 

Looking for an advanced yet user-friendly solution to improve inbox placement? With Snov.io Email Warm-up, you can find a ready-to-use warm-up strategy that fits your specific goals. Whether you’re preparing a new domain for cold campaigns or want to fix your domain reputation, you’ll be able to grow deliverability automatically, sparing hours of your precious time.

Aim for hyper-personalization

Therefore, to make your cold outreach more impactful, go beyond using first names. Reference a prospect’s company, role, or recent activity. You can also mention shared connections to build instant relevance and trust.

With Snov.io’s Cold Email tool, for example, you can personalize your bulk messaging on autopilot. Its advanced Dynamic content variables will help personalize each message in your sequence on the go, so it feels relevant and warm.

Meanwhile, with Snov.io’s Personalized AI Email Builder, you can create targeted messages based on your ICP and unique selling points.

No matter how many prospects are on your list, Snov.io’s AI-powered features will make each email feel personal and relevant to your prospects.

Segment your lead list

How do you ensure your outreach is relevant to all your leads? Group them by shared characteristics and tailor your messaging at scale. By segmenting your leads based on industry, job role, location, or other criteria, you can create emails that resonate with each group. More targeted cold outreach always brings better results. 

Optimize your sending schedule

Timing can make or break your open and response rates. Never send campaigns randomly! Instead, learn about your audience to align your schedule accordingly. The cold email statistics provided in this article will also be helpful.

Provide a catchy subject line and a clear CTA

Subject lines open the doors to your outreach, so make them:

• attention-grabbing 
• relevant
• clear

Meanwhile, CTA can significantly impact your reply rates. Ensure your recipient understands what you want them to do. Avoid vague phrases like “Let me know what you think.” Instead, consider adding action-oriented call-to-actions, such as “Would you be open to a 15-minute call?” to guide your prospect to the desired action.

Follow up strategically

Don’t give up after the first email. Most replies come after 2-3 follow-ups. Create a compelling follow-up sequence to move your prospect towards a response/action. Don’t repeat yourself in follow-ups – add fresh value to keep your cold campaigns effective.

A/B test to spot what’s working

Experiment with various approaches through A/B testing and analyze your results to identify the most effective options. Try out different subject lines, CTAs, texts, and other elements to see what works best. With valuable insights you gain, you’ll be able to adjust your next campaigns — a key strategy for boosting cold email open rates and other metrics.

The idea is simple: if we don’t keep our strategies fresh, we might miss out on connecting with potential clients. Our recent tweaks have upped our response rates to a steady 3-4%, but who knows how long that’ll last? So, we constantly optimize and test. Personalized content and smart timing are the main ingredients that grab the attention of busy execs.
