Open Rate Benchmarks for B2B Email Newsletters by Industry
You sent the newsletter. You checked the dashboard. The open rate says 28%.
Is that good? Is that terrible? Should you be relieved or quietly panicking?
Without a benchmark tied to your specific industry, that number tells you almost nothing. A 28% open rate is above average for a SaaS company and well below average for a professional services firm. Same number. Completely different story depending on where you sit.
This post gives you the actual benchmarks by industry, explains why open rates have gotten harder to read, and tells you which metrics actually matter more now.
The Big Caveat You Need to Read First
Before we get into the numbers, you need to understand something that changes how all of this data should be interpreted.
Since Apple launched Mail Privacy Protection (MPP) in late 2021, reported open rates have been significantly inflated. Apple Mail Privacy Protection accounts for nearly half of all email opens as of early 2025, with Apple's proxy server preloading tracking pixels before the recipient ever actually looks at the email. Your ESP records an open. The person may never have glanced at the subject line.
The B2B average email open rate is 15 to 25% for genuine human opens, and around 40% if you are looking at raw metrics inflated by Apple MPP. That gap is the single biggest source of confusion in email benchmarking right now.
This matters because almost every benchmark you will find online is now reporting the inflated number. The median email open rate across 3.6 million campaigns in MailerLite's dataset was 43.46% in 2025, a slight increase on 2024's average of 42.35%. That number sounds great. It is also not telling you what you think it is.
The right way to use these benchmarks: compare your number against others in the same dataset, using the same ESP. If everyone's numbers are inflated by the same factors, the relative comparisons still hold. But stop treating a 40% open rate as proof your emails are crushing it.
B2B Email Open Rate Benchmarks by Industry (2025 Data)
Here is where different B2B industries actually land, based on the most current available research.
Technology and SaaS
B2B email open rates by industry from a study of 939 companies show SaaS at 23%, Professional Services at 22%, Consulting at 21%, and Manufacturing at 19%. SaaS audiences are digitally native, but they are also flooded with vendor email. Their inboxes are noisy.
For SaaS and tech marketing emails, a practical baseline is mid-to-high 20s for open rates, with one 2025 benchmark set reporting about 29.2% average opens and another SaaS-focused dataset reporting 23.4%. Those ranges are normal. If your tech newsletter is hitting 25 to 30%, you are performing at or slightly above par.
Technology companies average 17 to 21% open rates, with regular product updates and educational content keeping subscribers engaged. If you are comparing against raw ESP data inflated by MPP, expect your dashboard to show something closer to 35 to 42%.
Professional Services and Consulting
Professional services tends to punch above average because the audience is smaller, more targeted, and subscribed with clearer intent. Newsletter-style emails have an average open rate of 41.3% in professional service sectors.
B2B services see 18 to 22% open rates when measuring actual human opens, with professional audiences checking email regularly and expecting relevant, targeted content.
If you run a consulting firm or professional services business and your newsletter is landing between 20 and 30% in your ESP dashboard, you are within a normal range. Above 35% consistently is a strong signal your content and list hygiene are working.
Finance and Investment
B2B finance sector emails average a 33.5% open rate. Finance audiences tend to be compliance-conscious and selective about what they engage with, which is why deliverability is especially important in this space. Deliverability rates reach 99.1% in financial services, the highest of any industry tracked. Clean lists and authenticated domains are non-negotiable here.
Real Estate
Real estate companies have an average open rate of 37.18%. This is an MPP-inflated figure, so actual engaged opens are lower, but real estate newsletters tend to perform well when the content is locally relevant and the sender is a recognized name in the recipient's market.
Manufacturing and Industrial
Manufacturing sits at the lower end of B2B benchmarks. Manufacturing averages 19% open rates, lagging behind SaaS and services due to a phone-first communication culture. If you are sending to plant managers and operations leads, email is not always their primary channel.
Marketing and Advertising
Marketing and advertising had some of the lowest click-to-open rates in MailerLite's 2025 benchmarks. Marketing professionals receive a high volume of email and are more likely to filter aggressively. Subject lines have to work harder in this space. If you are marketing to marketers, you are competing with people who write marketing email for a living.
Why Your Open Rate Varies More Than You Think
Two newsletters in the same industry can have drastically different open rates and it has nothing to do with content quality. These are the real drivers.
List quality. A list of 500 highly targeted subscribers who opted in because they needed your content will outperform a list of 5,000 scraped contacts every time. Industries with higher open rates tend to communicate with highly motivated, high-intent audiences, while lower-performing industries send to broader audiences with less targeted messaging.
Send frequency. The more often you send, the more your open rate will drop over time. This is not a failure. It is list fatigue working as it should. The subscribers who open every issue are your core audience. The ones who stopped opening are telling you something.
Subject lines. Using someone's name in a subject line increases opens by 26%. Specificity also helps. A subject line like "3 things your SaaS content calendar is missing" will consistently beat "This month's newsletter" regardless of what is inside.
Sender name. Emails sent from a real person outperform emails sent from a brand name or a generic address. Emails sent from named individuals versus generic company names see a 27% higher open rate.
Send day. Best send day varies by industry: SaaS peaks on Tuesday, Manufacturing on Wednesday, and Services on Thursday. If you are sending to a B2B audience on Friday afternoon, you are competing with the weekend.
The Metric That Matters More Than Open Rate
Here is the part most marketers skip.
Open rate is the wrong primary metric now. If you only track one metric after Apple MPP, make it click-to-open rate (CTOR), which sits at 6.81% average and is far more useful than raw open rate for understanding what happens after someone actually reads your email.
CTOR tells you what percentage of people who actually opened your email clicked something. It filters out the phantom opens and gives you a real signal on content quality and CTA effectiveness.
B2B click-through rates are 47% higher than B2C email campaigns, reflecting a more engaged, intent-driven audience.
The hierarchy to track in order of reliability:
First, deliverability and bounce rate. If your emails are not reaching inboxes, nothing else matters. Keep bounce rates below 2%.
Second, click-to-open rate. This is your content quality signal. The 2025 average is 6.81%. Above 10% is strong.
Third, click rate. The 2025 average across all industries is 2.09%. B2B tends to run slightly above this.
Fourth, open rate. Still worth tracking as a health indicator, but do not make it your headline KPI.
If your open rate jumped 15 points without a corresponding click-rate increase, you did not get better at email. Apple got better at preloading pixels.
What to Do If Your Open Rate Is Below Benchmark
If you are consistently landing below your industry average, start here before touching anything else.
Check your list health first. Run your list through a verification tool and remove hard bounces immediately. A dirty list is the most common reason open rates crater. It also damages your sender reputation over time, which compounds the problem.
Re-examine your subject lines. Look at your last ten sends and find the three with the highest open rates. What did they have in common? Specificity, urgency, personalization, or a direct question tends to win in B2B.
Segment your list. Sending the same email to everyone on your list is the fastest way to depress open rates. Even a basic split by role or company size will show you which segments are engaged and which are dead weight.
Check your send time. If you have never tested send day and time, start there. A simple A/B test on Tuesday morning versus Thursday morning can surface meaningful differences.
Sunset inactive subscribers. Anyone who has not opened in six months is dragging your rate down and hurting your deliverability. Send one reactivation email. If they do not open it, remove them. A smaller, engaged list beats a large, unresponsive one every time.
What This Means for the B2B Marketing Manager
If you are the one managing the newsletter while also running campaigns, briefing freelancers, writing landing pages, and answering your CEO's questions about content output, you probably do not have time to obsess over open rates.
That is the right instinct. Open rates are one signal among many, and they have gotten noisier since 2021. Your real goal is a list that clicks, reads, and converts. That comes from sending consistently valuable content to people who actually want it.
The companies that win in email are not the ones chasing vanity metrics. They are the ones showing up on a predictable schedule with content that earns the read.
If your newsletter content is the bottleneck because you are already stretched thin, that is a problem worth solving. Consistent content takes consistent time. And for most lean B2B marketing teams, that time does not exist.
