What is a good email open rate for marketing campaigns

TL;DR: Most benchmark articles tell you where your open rate sits, then leave the diagnosis to you. This one maps each benchmark to a specific cause, so IT company owners know not just whether their number is good but which lever to pull when it is not. You'll leave with a clear framework for reading your metrics and acting on them.

What is a good open rate for email marketing

A strong open rate for B2B marketing emails in 2026 sits between 35 and 45 percent. If your campaigns are landing in that range, you're performing well. Below 25 percent is a signal worth investigating. Above 50 percent almost certainly reflects Apple Mail Privacy Protection (MPP) inflation, not genuine engagement.

MPP has distorted raw open rate data since Apple launched iOS 15 in late 2021. When a recipient uses Apple Mail, iOS pre-fetches email content automatically, recording an "open" whether the person read the message or not. Litmus estimates that Apple Mail now accounts for roughly 50 percent of all email opens tracked globally. That means your reported open rate can look healthy while your actual readership is significantly lower.

This matters for IT company owners because most published benchmarks blend B2B and B2C data together, pulling the "average" down toward consumer email norms. A retail newsletter and a managed services provider email do not share the same audience, cadence, or context. Comparing your numbers to an all-industry average is the wrong baseline.

The more reliable signal in a post-MPP environment is your click-to-open rate (CTOR): clicks divided by confirmed opens. A B2B CTOR of 10 to 15 percent indicates that the people who did open your email found it worth acting on.

For a breakdown of how these benchmarks shift by vertical, open rate performance varies more than most benchmarks show across specific industries.

What is the average email open rate for B2B emails

The average email open rate for B2B emails sits between 20 and 40 percent depending on the source, but that range is nearly useless without context. Most benchmark reports blend B2C retail, nonprofit, and e-commerce data into a single "all-industry" figure, which pulls the average down. When you isolate B2B technology and IT services senders, email open rate benchmarks by industry consistently show a tighter range: 28 to 38 percent for well-maintained lists, with top-quartile senders hitting above 40 percent.

The catch is Apple Mail Privacy Protection (MPP), active since iOS 15 in late 2021. MPP pre-loads tracking pixels regardless of whether the recipient actually opened the message, which inflates raw open rate figures for any list with a meaningful share of Apple Mail users. For B2B IT audiences, that share is often 40 to 60 percent of contacts. Your platform may report 38 percent while your real engaged audience is closer to 22 percent.

So when you ask what is a good open rate for email marketing in a B2B context specifically, the honest answer is: measure against a MPP-adjusted baseline, not a raw figure. If your open rate looks strong but what happens after someone opens your email shows low click-through, MPP inflation is likely distorting the picture.

Before comparing yourself to any benchmark, run a quick audit of your sender reputation and list health to confirm you're reading clean data.

Is a 20% email open rate good

For most IT and SaaS senders, 20% sits below the current B2B baseline. Average B2B open rates in 2024–2025 cluster between 25% and 35% depending on list quality and segment, so a 20% figure is a warning signal, not a passing grade.

The diagnosis gets harder because Apple Mail Privacy Protection (MPP), introduced with iOS 15, pre-loads tracking pixels regardless of whether the recipient actually opens the message. That inflates reported opens for any list with a meaningful share of Apple Mail users. If your platform shows 20% post-MPP, your real engagement could be lower.

Two root causes account for most cases at this level:

• List decay : B2B contacts change roles frequently. A list that hasn't been cleaned in six months accumulates cold addresses that drag your average down and hurt deliverability.

• Sender reputation damage : High bounce rates or spam complaints suppress inbox placement before subject lines even matter. Run a quick audit of your sender reputation and list health before adjusting anything else.

Fix the foundation first. Creative changes won't move the number if delivery is already broken.

What factors affect email open rates

Four factors move the needle on open rates, and they don't carry equal weight. Fix them in this order.

• Sender reputation : Is the floor everything else rests on. If your domain or IP is flagged by Gmail or Outlook's filtering systems, your emails land in spam before a subject line ever gets read. A poor sender score can suppress deliverability enough that even a 40% open rate on delivered mail translates to near-zero reach. Run a quick audit of your sender reputation and list health before touching anything else.

• List hygiene : Is the second fix, and it directly protects your sender reputation. High bounce rates and low engagement signals (unopened mail sitting for 90+ days) tell inbox providers your list is stale. Most teams find that removing unengaged subscribers every quarter keeps bounce rates under 2%, which is the threshold most ESPs use to flag accounts for review. This is one of the most overlooked factors that affect email open rates, especially for IT companies running long nurture sequences.

• Subject line : Is where most teams start, but it's actually the third lever. A subject line can lift open rate by 10 to 15 percentage points on a clean, well-delivered list. On a list with deliverability problems, it changes almost nothing. Keep subject lines under 50 characters, avoid spam-trigger words like "free" or "guaranteed," and test one variable at a time.

• Send time : Has the smallest independent effect of the four, typically 3 to 8 percentage points depending on your audience's timezone and role. For B2B IT buyers, Tuesday through Thursday mornings tend to outperform Friday sends, but your own send history is more reliable than any general benchmark.

Understanding what is a good open rate for email marketing starts here: the benchmark you're chasing only matters if these four factors are working together. Once they are, open rates by industry give you a meaningful comparison point. And remember, opens are just the entry point — what happens after someone opens determines whether the send actually drove revenue.

How to improve your email open rates

Fix the four controllable factors in this order, because sequence matters: sender reputation degrades silently and poisons every other improvement you make, so it comes first.

1. Audit your sender reputation and list health : Check your domain's spam score and bounce rate before touching subject lines. A domain with a 5%+ hard bounce rate will land in spam regardless of how good your copy is. Run a quick audit of your sender reputation and list health before moving to step two.

2. Remove unengaged contacts : List hygiene is the fastest lever most IT company owners ignore. Segment anyone who hasn't opened in 90 days, run a re-engagement sequence of two emails, then suppress non-responders. Sending to a smaller, engaged list consistently outperforms blasting a large, stale one. Review bulk sending practices that protect deliverability if you're sending above 5,000 contacts per campaign.

3. Fix your subject line before you optimize send time : Subject line is the highest-leverage copy decision you make per campaign. Test one variable at a time: sender name vs. company name, question vs. statement, 4-word vs. 8-word. Most teams run A/B tests with sample sizes too small to be meaningful. Use at least 200 recipients per variant before calling a winner.

4. Dial in send time last : Once reputation and list quality are stable, send-time testing produces real signal. For B2B IT audiences, Tuesday and Wednesday mornings (8–10 a.m. recipient time zone) outperform Friday afternoons in most cases, but your own historical data beats any general benchmark. Check email open rate benchmarks by industry to calibrate what a realistic target looks like for your segment.

One caveat on measurement: Apple Mail Privacy Protection (MPP), active since iOS 15, pre-loads tracking pixels and inflates reported open rates for any list with a significant Apple Mail share. If your open rate jumped in late 2021 without a corresponding lift in replies or clicks, MPP is likely the cause. Track what happens after someone opens your email alongside open rate to get an honest read on how to improve email open rates that actually move pipeline.

How open rate connects to the metrics that drive revenue

Open rate is a leading indicator, not a destination. When your open rate climbs, reply rate and click-through typically follow, which means pipeline moves too. When it drops, the problem usually sits upstream: a deliverability issue, a list that's gone cold, or subject lines misaligned with what your audience actually cares about.

For B2B IT audiences, email open rate benchmarks by industry matter less than the directional signal your own rate sends week over week. A 38% open rate that's falling is a worse position than a 22% rate that's climbing.

The chain looks like this: open rate predicts whether your message reaches attention. Attention predicts clicks. Clicks predict replies and conversions. What happens after someone opens your email determines whether that open ever touches revenue.

Asking "what is a good open rate for email marketing" is the right starting question. The sharper follow-up is: what does my open rate tell me about the health of the steps that come after it?

Open rate vs. click-to-open rate: which number to trust

Open rate tells you how many people opened. Click-to-open rate (CTOR) tells you how many of those openers actually engaged. That distinction matters more now that Apple Mail Privacy Protection pre-loads open pixels, inflating raw open rates for anyone with Apple Mail users on their list.

CTOR is calculated as clicks divided by unique opens. Because both numbers come from the same pool of "opened" messages, MPP inflation affects the denominator and numerator equally, making CTOR a more stable signal when you're trying to diagnose whether your content is working.

A practical way to use both: track open rate as a deliverability and subject-line indicator, then use CTOR to judge what happens after someone opens your email. If open rate looks healthy but CTOR is flat, the subject line is doing its job and the body copy isn't.

For B2B IT senders, understanding the email open rate benchmarks by industry gives you a baseline before drawing conclusions from either metric.

Closing

A good open rate sits between 35 and 45 percent for B2B in 2026, but that number only matters if your sender reputation, list hygiene, subject lines, and send times are all working together. Most teams chase subject line tweaks when the real problem is deliverability or list decay. Start with an audit of your sender reputation and bounce rate, then move through the levers in order. If you're manually checking open rates week to week and adjusting subject lines campaign by campaign, that's a sign your workflow needs automation. Evox tracks sender reputation continuously and runs automated send-time and subject line tests so your open rate improves without a weekly audit. What's your current bounce rate, and when was the last time you cleaned your list?
