Email Marketing Benchmarks 2026: Open Rates, CTR, and What 'Good' Looks Like
Industry email marketing benchmarks for 2026. Open rates, click-through rates, and the metrics that actually matter after Apple Mail Privacy Protection.
Email marketing has an ROI problem. Not because the ROI is bad. Because it is so good that people do not believe the numbers. Litmus pegged email ROI at $36 for every $1 spent in 2022. The DMA (Data & Marketing Association) has reported similar figures for years. No other marketing channel comes close.
But knowing email works and knowing whether your emails work are different questions. That is what benchmarks are for. They give you a reference point: is your 22% open rate good, mediocre, or embarrassing? The answer depends on your industry, your email type, and whether you are even measuring the right things anymore.
The benchmark landscape in 2026
Here are the numbers most commonly cited across major email platforms (Mailchimp, Campaign Monitor, Klaviyo, HubSpot).
Open rates
The average email open rate across industries sits between 20% and 25%. But this number comes with a giant asterisk.
Apple Mail Privacy Protection, launched with iOS 15 in September 2021, pre-fetches email content for Apple Mail users regardless of whether the recipient actually opens the email. This means Apple Mail users register as "opened" even when they never looked at your email. Since Apple Mail accounts for roughly 50% to 60% of email opens in many markets (Litmus Email Client Market Share, 2024), open rates are systematically inflated.
The practical impact: your reported open rate is probably 5 to 15 percentage points higher than your actual open rate. A "25% open rate" might really be 15% in terms of humans who actually read the email.
This does not make open rates useless. They are still useful for relative comparisons (A/B testing subject lines within the same audience), but the absolute number is no longer trustworthy as a standalone metric.
Click-through rate
Average click-through rate (CTR) across industries: 2% to 3%. This metric was not affected by Apple's privacy changes and remains reliable.
CTR tells you whether the content inside your email was compelling enough to drive action. A 2.5% CTR on a list of 10,000 means 250 people clicked. That is 250 people who took the next step, and unlike open rate, there is no ambiguity about whether it happened.
Click-to-open rate
Click-to-open rate (CTOR) measures clicks as a percentage of opens. Average: 10% to 15%. This metric used to be useful for isolating content quality from subject line performance, but Apple Mail Privacy Protection inflated the denominator (opens), which deflated CTOR artificially. Use it cautiously.
The headline number is impressive: 81% of sales teams are either experimenting with or have deployed AI (Salesforce, 2025). But look one layer deeper and the picture gets more complicated. Only 45% of those teams use AI on a weekly basis (Salesforce, 2025). Th
76% of marketing teams now use AI in core operations, up from 29% in 2021. The AI marketing market is valued at $47.32 billion in 2025, on track to reach $107.5 billion by 2028. ChatGPT referrals convert at 15.9%, while Google organic sits at 1.76%. 39% of CMO
Every quarter, a new report drops claiming AI will transform marketing. Most of these reports say the same thing with slightly different numbers. So here is what we did: we pulled the most credible sources (McKinsey, Stanford HAI, HubSpot, Gartner) and stitche
Unsubscribe rate
Average unsubscribe rate: 0.1% to 0.3% per email. Anything above 0.5% per send is a warning sign. It means your content is consistently missing expectations, you are emailing too frequently, or your list includes people who never wanted to be on it.
Spam complaint rate
Average: below 0.1%. Google and Yahoo implemented stricter sender requirements in February 2024, requiring bulk senders to keep spam complaint rates below 0.3% and offering a recommended threshold of 0.1%. Exceeding these limits can result in emails being blocked entirely. Monitor this number closely.
Benchmarks by email type
Not all emails are created equal. Transactional and triggered emails dramatically outperform bulk sends.
Welcome emails
Open rate: 50% to 60%. CTR: 5% to 10%.
Welcome emails are the highest-performing email type because they arrive at the moment of peak interest. Someone just signed up, purchased, or subscribed. They are paying attention. If your welcome email is below 40% open rate, something is wrong: it is arriving too late, the subject line is generic, or the from name is unrecognizable.
Abandoned cart emails
Open rate: 40% to 45%. CTR: 5% to 10%. Revenue recovery: highly variable, but Klaviyo reports that abandoned cart flows generate an average of $5.81 per recipient.
These emails work because the intent was already there. The customer added items to their cart. They were close to buying. A well-timed reminder (ideally within 1 to 4 hours) with the specific items they left behind converts at rates that no newsletter will ever match.
Newsletters
Open rate: 15% to 25%. CTR: 1% to 3%.
Newsletters are the workhorse of email marketing, but they also have the widest performance range. A well-segmented, consistently valuable newsletter can hit 35% open rates. A generic, unsegmented blast will struggle to break 15%.
Promotional emails
Open rate: 15% to 20%. CTR: 1% to 2%.
Promotional emails (sales, discounts, product launches) perform below newsletters on average because subscribers expect them to be self-serving. The exception: genuinely exclusive offers sent to engaged segments. Those can outperform newsletters significantly.
What to actually measure in 2026
Open rate was the primary email KPI for two decades. That era is over. Here is what to track instead.
Click rate
Total clicks divided by total emails delivered. This is your primary engagement metric. It measures real human behavior that Apple cannot fake. Track it over time, by segment, and by email type.
Revenue per email
Total revenue attributed to an email divided by total emails delivered. This is the metric your CFO cares about. It connects email directly to business outcomes. Every modern email platform (Klaviyo, Mailchimp, HubSpot, ActiveCampaign) offers revenue attribution. Use it.
List growth rate
New subscribers minus unsubscribes and bounces, divided by total list size. A healthy list grows at 2% to 5% per month. If your list is shrinking, you are losing ground regardless of how well individual emails perform.
Spam complaint rate
As noted above, Google and Yahoo now enforce hard limits. Track this per campaign. A single bad send can damage your sender reputation for weeks.
Revenue per subscriber
Total email-attributed revenue divided by total subscribers. This tells you the health of your list as an asset. If revenue per subscriber is declining while your list grows, you are adding low-quality subscribers who dilute the value of your audience.
The segmentation multiplier
Segmented email campaigns dramatically outperform unsegmented blasts. Mailchimp's widely cited data shows segmented campaigns generate 14% higher open rates and 100% higher click rates compared to non-segmented campaigns.
Segmentation does not need to be complicated. Start with these three:
Purchase behavior
Separate buyers from non-buyers. Send product recommendations to buyers. Send social proof and introductory offers to non-buyers. This single split will improve performance immediately.
Engagement recency
Segment by when someone last clicked an email. Active subscribers (clicked in the last 30 days) get your full send cadence. Lapsed subscribers (no click in 90+ days) get a re-engagement sequence or reduced frequency. Dead weight (no click in 180+ days) gets sunset: one final re-engagement attempt, then removal.
Removing unengaged subscribers feels counterintuitive, but it improves deliverability for everyone who remains. Email providers use engagement signals to determine inbox placement. A list full of people who never open hurts your ability to reach the people who do.
Lifecycle stage
New subscribers get education and trust-building content. Active customers get product tips, cross-sells, and loyalty rewards. Churned customers get win-back sequences. The message should match where the person is in their relationship with your brand.
Subject line testing: what the data says
Subject lines determine whether your email gets opened or ignored. Here is what consistently performs in testing.
Personalization
Including the recipient's first name in the subject line increases open rate by 10% to 20% in most tests. It is the simplest optimization available. Use it, but do not rely on it exclusively. A personalized subject line on a bad email is still a bad email.
Numbers and specifics
"5 ways to reduce your energy bill" outperforms "Ways to reduce your energy bill." Numbers create specificity and set expectations. The reader knows exactly what they are getting, which reduces the friction of opening.
Curiosity gaps
Subject lines that hint at valuable information without revealing it drive opens. "The metric we stopped tracking (and why revenue went up)" creates a gap that the reader needs to close. Use this sparingly. Overuse trains your audience to expect clickbait, and they stop opening.
What to avoid
ALL CAPS, excessive punctuation (!!!), and spam trigger words ("free," "act now," "limited time") hurt deliverability and erode trust. Urgency works when it is real. "Sale ends tonight" is fine if the sale actually ends tonight. "URGENT: Don't miss this!!!" is spam behavior.
Putting benchmarks in context
Benchmarks are reference points, not targets. A 20% open rate is excellent for a 500,000-person list and mediocre for a 2,000-person list of highly engaged fans. Industry matters too: nonprofit and government emails typically see higher open rates (25%+) than retail and e-commerce (15% to 20%).
The most useful comparison is against your own past performance. Are your click rates trending up or down over the last six months? Is revenue per email growing? Is your list healthy and engaged?
