What's a Good Email Open Rate?
Real Benchmarks · By Audience · By Industry · With Sources
Ask this question online and you'll find answers ranging from 19% to 43% — all claiming to be “the average.” The honest truth: there is no single good open rate, because the number depends enormously on who you're emailing. A message to loyal customers and a cold email to strangers live in completely different worlds. This page gives you the real benchmarks for each audience, the industry data, why the published numbers disagree — and links to every source, so you can check our work.
How an “open” gets counted — and why the experts can't agree on the average
Your open rate is simply the percentage of delivered emails that got opened. The measuring method is worth knowing, because it explains everything odd about this metric: email platforms hide a tiny invisible image (a “tracking pixel”) in each message, and when someone's mail app loads that image, an “open” is recorded. Clever — and imperfect. Some apps block images (real opens go uncounted), and, far more consequentially, some apps load them automatically whether the human ever looked or not.
That's the story behind the wildly conflicting “averages” you'll find online. In 2021, Apple introduced Mail Privacy Protection, which pre-loads every email's images for Apple Mail users — recording an “open” even for messages deleted unread. HubSpot cites a study of 80,000+ email accounts that found reported open rates jumped roughly 18 percentage points after the change. So today's benchmarks split into two camps: studies counting everything report averages in the 40s — MailerLite's analysis of 3.6 million campaigns puts 2025's average at 43.46% — while studies filtering out the Apple auto-opens report far lower: Brevo's 2026 benchmark across 175,000 businesses found 20.73% excluding the inflation (33.87% with it). Neither is lying; they're measuring differently.
What this means for you, practically: don't chase one magic number from a headline. Compare yourself against the benchmark measured the way your platform measures (most platforms count everything, so the higher benchmarks apply), watch your own trend line month over month — the most honest comparison is you versus past-you — and put your real trust in clicks and replies, which no privacy feature inflates. That's the good, clean analytics way.
And Then There's the Variable That Dwarfs All Others
Measurement quirks move the number by points. Who you're emailing moves it by multiples. The same business, sending the same quality of email, will see dramatically different open rates from customers who love them, subscribers who opted in, strangers who've never heard of them, and — worst of all — a list of names purchased from a broker. Most “is my open rate good?” confusion dissolves the moment you benchmark against the right audience type. That's the next section, and it's the heart of this page.
Four audiences, four completely different scoreboards
Before comparing your open rate to anything, identify which of these you're emailing — because each plays an entirely different game:
Current Customers & Clients
People with an active relationship and money on the table — they want your emails. Appointment reminders, order updates, and account emails routinely open in the 50–80%+ range (welcome emails to brand-new subscribers average around 80%), and even promotional sends to customers should comfortably beat every general benchmark. If customer emails are underperforming your overall average, something specific is wrong — usually deliverability or a stale list.
→ Healthy zone: well above the averages — think 35–60%+Warm Contacts & Opted-In Subscribers
Newsletter subscribers, past customers, event signups, people who asked to hear from you. This is who every published “average” describes: ~43% counting everything (MailerLite), ~21% with Apple's inflation removed (Brevo) — with Brevo's top 10% of senders reaching 44%. Where you land in that range depends mostly on list hygiene, sender recognition, and how consistently you've earned attention.
→ Healthy zone: 25–45% on most platforms; watch your trend lineCold Contacts (People Who Don't Know You)
Prospecting emails to strangers play by outbound rules, where average opens run around 27–28% and — the metric that actually matters here — reply rates average just 3–5%, with 5–10% considered solid (Instantly). Under ~20% opens usually signals a deliverability problem, not a subject-line problem, per BuzzLead's benchmarks. Cold email done legally (real sender info, honest subject, working unsubscribe) is legitimate — just never confuse its scoreboard with your newsletter's.
→ Healthy zone: 25–40% opens; judge by replies, not opensBought & Rented Lists
There's no “good open rate” benchmark for purchased lists, and that absence is the message. These lists are riddled with dead addresses and spam traps, the recipients never agreed to hear from you, and mainstream platforms (Mailchimp, Constant Contact, and peers) prohibit purchased lists outright in their terms — accounts get suspended for it. Worse than the wasted money: the flood of bounces and spam complaints damages your sender reputation, dragging down deliverability to the customers and subscribers who do want your email.
→ Healthy zone: doesn't exist — the kindest data-driven advice is simply don'tThe pattern worth noticing: open rates track relationship warmth more than they track email skill. The same subject line might open at 60% with customers, 30% with subscribers, and 25% with strangers. Which points to the real long game: everything that moves contacts up this ladder — great service, an honest opt-in list, consistent value — raises every email metric you have. List quality beats copywriting cleverness, every time.
Benchmarks by industry & audience — every number linked to its source
These come from the major published studies, each analyzing thousands to millions of real campaigns. Reminder from above: sources that filter out Apple's auto-opens (like Brevo) report lower numbers than those that don't (like MailerLite) — both views are included so you can compare against the one matching how your platform counts.
| Segment | Benchmark | Worth Knowing | Source |
|---|---|---|---|
| All industries (everything counted) | 43.46% open · 2.09% click | 3.6 million campaigns analyzed; includes Apple's auto-opens | MailerLite 2025 |
| All industries (Apple inflation removed) | 20.73% open (33.87% with it) · 2.27% click | 175,000+ businesses; top 10% of senders reach 44% — segmentation matters that much | Brevo 2026 |
| B2B (business-to-business) | ~39.5% open | Professional audiences engage well with genuinely useful, human-sounding email | HubSpot |
| E-commerce & retail | 37.93% open | Klaviyo data across e-commerce senders; promotional volume runs high in this space | Klaviyo via Flowium |
| Nonprofits | 28.59% open · 3.29% click | Mission-driven audiences click at well above commercial averages — supporters genuinely want the updates | Neon One |
| Nonprofit fundraising sends | $58 raised per 1,000 messages · 0.48% click | The gold-standard annual nonprofit study — proof that results-per-send, not opens, is the metric fundraisers live by | M+R Benchmarks 2025 |
| Government & public sector | 30.5% open (top of its dataset) | From a lower-baseline dataset (19.21% overall avg) — institutional email earns unusually high trust; nonprofits (25.2%) and education (23.4%) follow | WebFX 2026 |
| Cold outreach (opens) | ~27.7% open average | Down from ~36% in 2023 as inboxes tighten; under 20% usually means a deliverability problem | Martal compilation |
| Cold outreach (replies — the real metric) | 3–5% average reply · 5–10% is solid | Benchmarks from millions of sends; the strictest studies (net-new contacts only) run even lower — cold email is a numbers game played politely | Instantly / Backlinko / Belkins |
Why the sources are right there in the table: benchmark numbers get repeated around the internet until nobody remembers where they came from — and stale or misquoted stats lead to real decisions made on fiction. Every figure above links to the study that published it, with its methodology, so you (and we) can check the work. When these studies update annually, we'll refresh this page. That's how we believe data deserves to be treated.
The 10 factors behind every open rate — in order of how much they matter
Most advice starts (and ends) with subject lines. Subject lines are real — and they're fourth on this list:
Factor 01 · Before Anything Else
Deliverability — actually reaching the inbox
An email in the spam folder has a 0% open rate no matter how brilliant it is. Authentication records (SPF, DKIM, DMARC), sender reputation, and list quality decide whether you're even in the room. If your open rate sits below ~15%, look here first — it's rarely a creativity problem. Our Why Are My Emails Going to Spam? guide is the full deep-dive.
Factor 02
Who the list is (the audience ladder)
Everything from the four-audiences section: relationship warmth moves opens by multiples, not points. A modest email to a genuinely opted-in list outperforms a masterpiece to strangers. Grow the list slowly and honestly; it pays compounding interest on every send forever.
Factor 03
The sender name they recognize (or don't)
Before anyone reads your subject line, they read who it's from — and familiarity is the fastest yes/no in the inbox. Use a consistent, recognizable sender (“Rachel at Mindful Marketing” beats “no-reply@” every day), and never change it casually; each change resets recognition to zero.
Factor 04
The subject line (yes, finally)
Clear beats clever, specific beats vague, and honest beats hype — subject lines that overpromise train people to stop opening. Keep it under ~50 characters for mobile, make the preview text (the gray line after the subject) pull its weight, and skip the ALL CAPS and !!! that spam filters and humans both dislike.
Factor 05
List hygiene — pruning the ghosts
Dead addresses and long-gone subscribers drag the percentage down and quietly hurt deliverability (mailbox providers notice when you keep emailing the disengaged). A yearly sweep — re-engagement campaign first, then a respectful goodbye to the silent — often lifts open rates more than any copywriting change. A smaller, real list beats a big, hollow one.
Factor 06
Segmentation — right message, right people
Brevo's finding that top senders more than double the average comes down largely to this: sending the customer email to customers and the prospect email to prospects. Even two or three simple segments (customers / subscribers / event contacts) noticeably outperform one-blast-fits-all.
Factor 07
Frequency & fatigue
Email too rarely and people forget who you are; too often and they tune out (or unsubscribe — watch that rate alongside opens). There's no universal magic cadence: the honest rule is to email when you have something genuinely worth their minute, on a rhythm you can sustain. Consistency at monthly beats brilliance at random.
Factor 08
Timing — real but overrated
Mid-week, mid-morning sends test well in aggregate studies — and your audience is not an aggregate. Timing is worth a simple experiment (same email style, two different slots, compare), then settling on what your list responds to. It's a single-digit-points factor; don't let it eat the attention the top factors deserve.
Factor 09
Mobile reality
The majority of opens happen on phones, where your subject gets ~40 characters, your preview text decides the swipe, and a clunky mobile layout gets deleted in seconds — teaching recipients not to bother next time. Every send deserves one glance on an actual phone before it goes out.
Factor 10 · The Long Game
The track record you've built
Every email teaches your list whether opening you is worth it. Consistently useful, honest sends raise your future open rates; consistently salesy or empty ones lower them — no subject line can outrun a reputation. The best open-rate strategy is unglamorous: be reliably worth opening, for months. It works, and nothing else works without it.
Opens start the story — they never finish it
An open is a glance, not a result — and as we've seen, sometimes not even a glance. Good, clean analytics means watching the metrics that reflect what people actually did:
The Metrics That Don't Lie
Clicks, replies, unsubscribes & results
Click rate (2–3% is typical across studies) shows genuine interest — no privacy feature fakes a click. Click-to-open rate tells you whether the email delivered on its subject line's promise. Replies are the gold metric for anything conversational. Unsubscribes (healthy is under ~0.3–0.5%) are your fatigue alarm. And the final boss: results per send — inquiries, bookings, donations. It's why M+R measures nonprofit email in dollars raised per 1,000 messages ($58), not in opens.
How We Watch It
Email in the one clear dashboard
For our clients, email metrics don't live alone in a platform tab — they sit beside website traffic, social, and listings in one visual dashboard, with UTM-tagged links connecting every send to what readers did after the click, on clean GA4 data. Reviewed together in plain English — week over week, month over month, year over year — so “is our email working?” always has a current, honest answer. That's the whole clean-analytics philosophy, applied to the inbox.

From “is this good?” to genuinely better — six steps
In order — because fixing them out of order (say, polishing subject lines while your emails land in spam) wastes effort:
Pull Your Real Numbers
Open your email platform's reports (every platform has them — usually under “Reports,” “Analytics,” or per-campaign stats) and write down three numbers from your last several sends: open rate, click rate, unsubscribe rate. Not remembered, not estimated — the actual figures. Improvement starts with an honest baseline.
Benchmark Against the Right Row
Match your numbers to your audience type (the four-audiences section) and your industry (the table above). A 28% open rate is concerning for customer emails, perfectly healthy for a nonprofit's full list, and excellent for cold outreach. Most open-rate anxiety ends right here, at the correct comparison.
If You're Well Below Benchmark — Check Deliverability First
Open rates under ~15% on a warm list almost always mean a chunk of your email never reaches inboxes. Before touching a single subject line, verify your authentication (SPF, DKIM, DMARC) and sender reputation — our Why Are My Emails Going to Spam? guide walks through the whole checkup in plain English. Fixing deliverability routinely produces the biggest single jump on this page.
Clean the List, Then Segment It
Run a re-engagement send to subscribers who haven't opened in 6–12 months (“still want to hear from us?”), then respectfully remove the silent — your percentage rises immediately and your sender reputation thanks you. Then create your first simple segments: customers, subscribers, prospects. Even this basic split lets every group get mail that actually fits them.
Sharpen the Envelope: Sender & Subject
Lock in one recognizable sender name and keep it forever. Then work the subject-line craft: clear over clever, under ~50 characters, preview text written on purpose, no hype. If your platform offers A/B testing, test one subject variable per send and let your own audience — not a blog post — tell you what works on them.
Graduate to the Metrics That Matter
Tag every email link with UTM parameters so clicks flow into GA4 with your email's name on them — then judge each send by clicks, replies, and what readers did on your site afterward. Review the trend monthly: is this quarter's you beating last quarter's you? That's the question that actually grows a business; the open rate was only ever the doorway to it.
