Apple Mail now fakes 64.66% of your email opens: why cold email open rates lie (and what to track instead)

Almost two-thirds of your tracked email opens never happened. According to Litmus’ May 2026 email client market share report (based on more than one billion tracked opens), Apple accounts for 64.66% of all tracked email opens. Here’s the problem: Apple Mail Privacy Protection pre-fetches tracking pixels at delivery, so those register as “opens” whether or not the recipient actually reads the email. Your 50% open rate could be mostly bots.

In this article, I’ll break down exactly why cold email open rate has become an unreliable vanity metric and show you which signals actually correlate with pipeline. Then I’ll walk you through how to track inbox placement instead of phantom opens.

What are open rates and how relevant are they?

Open rate is the result of a simple calculation: number of emails opened / number of emails sent (percentage).

So, if you send 200 emails and 100 people open your email, you’ll have a 50% open rate. But what does that really mean in 2026, when most of those opens may never have happened?

Most cold email platforms track opens by embedding a tiny invisible image (a tracking pixel) in your message. When someone’s email client loads that image, the platform counts it as an open. That method is exactly where the trouble starts.

What’s a good cold email open rate in 2026? (and why the number lies)

If you’ve been searching for a benchmark, you’ve probably noticed the numbers swing wildly. Some reports claim average cold email open rates hover around 21%. Others push past 60%. That gap should tell you something: the metric itself has broken down.

The reason is Apple Mail Privacy Protection. Litmus’ May 2026 report found that Apple accounts for 64.66% of all tracked email opens. Because Apple pre-fetches tracking pixels at delivery, those opens register whether or not anyone actually reads the message. A prospect who deleted your email unopened still counts as an “open.”

That’s why Belkins’ 2026 study, which analyzed 7,530,489 cold emails sent in 2025, stopped tracking open rates entirely. They switched to reply rate as the primary engagement signal and found an average reply rate of 0.45% (unique replies divided by emails sent).

So if you need a benchmark, here it is: stop benchmarking open rate. A 0.45% reply rate on millions of emails is a more honest signal than any open rate inflated by bots. The question that actually matters is whether your emails are reaching the inbox, and whether real humans are writing back.

That said, if you keep open tracking on for a short diagnostic window, the number can still flag a deliverability problem. Read it as a direction, not a score, and always in light of your domain’s age:

• •

  Brand-new domain (first 30 days): 5% to 20%. You’re still building reputation, so low numbers here are expected, not alarming. What matters is whether the number trends up week over week.

• •

  Below 25% on a warmed domain: something’s broken. Your emails are probably landing in spam, your list contains invalid addresses, or your subject lines aren’t earning attention.

• •

  40% to 60% on a warmed domain: the healthy range. It lines up with the >50% we’ve always recommended as a sign your deliverability is fine.

And beat your own baseline instead of chasing someone else’s average. If you’re at 20% today, getting to 35% matters more than matching a number collected from a different audience, list, and mail-client mix.

Why have we been tracking open rates?

For years, the #1 goal of open rates was to know if your prospects were interested in what you sent them by checking if they opened it.

But in the past few years, the most important part of open rates has been to help you see if your emails are being delivered, telling you whether you are landing in the inbox or dropping into spam.

We’ve always recommended having a >50% open rate, meaning you don’t have an issue with your deliverability.

But because of the new privacy updates, open rates are no longer the go-to metric for email deliverability (more on that in a minute).

Another use of open rates has been to determine if your subject lines perform well or not. The logic behind this is pretty simple: if an email was opened out of all the emails in the inbox it was probably thanks to the subject line and/or the email’s first line, right?

Well, it turns out it was too good to be true.

After testing 20+ of our competitors (Salesloft, Outreach, Mailshake, Woodpecker, Reply etc…) we realized that open rates are being calculated with misleading information.

So the open rate you see isn’t a good predictor of how many people opened your email thanks to the subject line or email’s first line.

Two approaches to open rates

We find the technical explanation (don’t worry, it’s not as scary as you think) to why cold email open rates aren’t working for you, and solutions on the business side.

The technical explanation

To make a long story short, inboxes are screwing us over.

How?

• •

  For safety and privacy reasons, some inboxes have spam filters and bots that open your emails and click on the links you have in them. This means it’s counted as an open or a click when the prospect may have never opened the email in the first place. Worse, the bots may have put your email directly in the spam folder.

• •

  If the email you sent is deleted (or even bounced after being opened by a bot) without the lead reading it, it’ll get marked as opened. Even if your lead never read the message.

• •

  Some email providers (like Outlook) have a preview mode so people can “open” the email without actually opening it, they are just moving or deleting it. That still counts as an open.

• •

  Apple Mail Privacy Protection pre-loads every remote image and pixel by default, marking the email opened the moment it is delivered, before the recipient touches it.

That means a ton of emails are being marked as opened that might not even make it to the inbox. And there are a good amount of emails being read that aren’t tracked.

But that’s not even the height of the technical problems. Tracking open rates increases your likelihood of landing in spam.

How? All email tools add a pixel to your emails to track the opens. So we bulk analyzed tens of millions of cold emails sent by our 65,000+ users worldwide to check whether having a pixel or image would decrease deliverability.

We found out that spam filters used by ESPs (Email Service Providers) can easily differentiate an image vs. a tracking pixel.

When a tracking pixel is used, the likelihood of your emails landing in spam was 15% higher than without tracking.

However, images did not impact the deliverability at all.

The business metrics that matter

Don’t worry, by not tracking open rates you aren’t losing any vital information.

The truth is that open rates have nothing to do with the success of your outreach or the growth of your business.

Instead, here are the signals worth your attention, each one closer to revenue than an open ever was:

• •

  Interested reply rates. With interested reply rates, you’re able to measure how appealing your campaign is to your prospects. If they’ve shown interest in your first approach, you know your campaign is landing, and where it needs tweaking further along the funnel.

• •

  Qualified meetings booked. Your prospects have set aside time out of their day to meet with you. Here you know the real impact of your campaign and your offer.

• •

  Pipeline created. Track the opportunities your outreach actually opened, so you can tie a campaign to the deals it influenced.

• •

  Business generated (dollar bills y’all). By far the best metric to focus on is how successful your campaign ultimately was: the prospects that made it through the entire sales funnel and bought.

Opens and clicks are vanity metrics. They’re just assumptions that people are interested in what you’re offering, and those assumptions are misleading for the technical reasons above.

Positive replies and booked meetings are the real signs your targeted prospects are interested, and both tie straight to revenue.

The 30/30/50 rule: find where your funnel breaks

Here’s the framework we use at lemlist to diagnose where a campaign breaks down. Three checkpoints, each one isolating a different failure:

• •

  Open rate: 30%+. It measures your subject line and deliverability. Below that, fix deliverability and subject lines first.

• •

  Reply rate: 30%+ of opens. It measures your body copy and relevance. If opens are fine but replies are low, the problem is your message.

• •

  Meeting rate: 50%+ of replies. It measures your offer and call-to-action. If replies are fine but meetings aren’t booking, revisit your offer.

Since bots inflate opens, treat the first checkpoint as a floor, not a win. The two that follow are the ones tied to revenue.

How to actually track cold email deliverability in 2026

Open rate tells you a tracking pixel fired. It doesn’t tell you whether your email landed in the primary inbox or went straight to spam. That distinction decides whether a prospect ever sees your message.

If your emails are going to spam, your open rate sits near zero no matter how sharp your subject line is. Inbox placement is the foundation; open rate is just the outcome.

Google’s Gmail sender guidelines, enforced since February 2024, require bulk senders (5,000+ emails per day) to keep spam complaint rates below 0.3%. Google recommends staying below 0.1%. Cross that threshold and your domain reputation tanks. Your emails stop reaching inboxes. Open rate drops, but it can’t tell you why.

lemlist’s Deliverability Hub gives you the signals open rate hides. Before you send, Deliverability Boost checks your copy and technical setup. It evaluates inbox-placement signals and flags risks before anything goes out. The platform rotates mailboxes and sends based on recipient timezone. Email verification cuts bounces before they hurt your domain, and lemwarm warm-up is built in.

lemlist’s deliverability monitoring and alerts take it further. Inbox placement testing sends to real addresses across Google and Microsoft and shows you exactly whether you’re hitting primary or spam. You get one view of warmup health, outreach performance, inbox placement, and domain reputation, filterable by mailbox or provider. Real-time alerts surface bounce or spam trends the moment they emerge, so you can fix problems before they compound.

Before a big campaign goes out, you can also send a test to your own Gmail, Outlook, and Yahoo accounts. Providers filter differently from each other, so this catches problems an open-rate dashboard misses entirely.

Where are open rates leading us?

Every year we move toward increasing privacy regulations. Lately, GDPR (in Europe), CCPA (in California), and rules in other places are limiting the data we can track.

An example is the cookie popups you come across whenever you open a website.

Then you have companies like Apple that decided to cut their email tracking to protect the privacy of their users. Lots of other big companies are following suit.

Again, this makes your open rates completely unreliable. But it also gives us a clear opportunity: focus on what really matters, generating conversations and building relationships, and bring the most value possible to your prospects.

Why your cold email open rate is low

When your open rate suddenly drops, it’s rarely one issue. Usually your technical setup, your list, and your messaging are working against you at the same time. Here are the usual suspects:

• •

  Poor sender reputation. Gmail and Outlook score every sending domain and IP. New domains without sending history start low, and so do domains that sent to bad addresses, triggered spam complaints, or ramped up volume too fast. Watch for opens dropping across all campaigns, emails landing in spam even for contacts who replied before, bounce rates climbing above 5%, and reply rates falling while opens stay flat. Here’s how providers calculate your sender reputation score.

• •

  Missing SPF, DKIM, and DMARC. These DNS records tell inbox providers you’re authorized to send from your domain. SPF lists which servers can send on your behalf, DKIM signs the message to prove it wasn’t altered, and DMARC tells providers what to do when either check fails. Without them, your emails look suspicious from day one.

• •

  HELO and reverse DNS mismatch. The layer most senders never check. When the hostname your server announces in its SMTP greeting doesn’t match the reverse DNS record for its IP, filters read it as a spoofing signal and score you down, even with SPF, DKIM, and DMARC set correctly.

• •

  Weak or spammy subject lines. Generic ones get ignored, salesy ones trigger filters. “Quick question,” “Just checking in,” all caps, and exclamation marks are overused and frequently flagged.

• •

  Unverified lead lists. Invalid addresses bounce, bounces damage your reputation, and a damaged reputation pushes your next emails to spam. Purchased or scraped lists make that cycle compound fast.

• •

  Volume spikes without warm-up. A brand-new domain sending 500 emails on day one looks exactly like spam, because that’s what spam does.

Diagnose before you optimize: a low open rate on a verified list points to deliverability, while a low open rate on an unverified list points to data quality.

What should you do to improve your results?

This article’s been a bit of a bummer, but I have good news. There’s a step-by-step process you can follow to stay out of spam and boost your outreach results (AKA generate more business).

On the tech side:

• •

  Turn open rate tracking off in your cold outreach tool to increase your deliverability.

• •

  Authenticate your domain with SPF, DKIM, and DMARC. In lemlist, authentication is handled automatically when you connect or purchase a sending domain, no manual DNS configuration required.

• •

  Follow deliverability best practices around technical setup, sending limits, and list hygiene.

• •

  Keep your warm-up running at all times so your reputation keeps building even between campaigns. For a new mailbox, start at low volume and ramp up over two to four weeks before you scale; lemwarm, included with every lemlist seat, handles it automatically.

• •

  Verify your list before you send and remove invalid, catch-all, and role-based addresses. lemlist enriches contacts with verified emails from multiple data providers, so you start with clean data.

• •

  Cap daily volume per mailbox and spread sends across several mailboxes. lemlist automates volume caps and mailbox rotation for you.

• •

  Send in your prospect’s timezone. Tuesday to Thursday mornings tend to work well for B2B, but local timing matters more than any universal “best time.” lemlist supports timezone-based sending windows so your emails arrive when prospects actually check their inbox.

• •

  Run inbox placement tests before you scale, so you catch a spam problem before it costs you a campaign.

On the business side, your goal is to increase business, and open rates have nothing to do with that. You’ll get much better results here:

• •

  Focus on the metrics tied to revenue: interested replies, qualified meetings booked, pipeline created, and deals closed.

• •

  Target the right leads: only reach out to people you can genuinely help.

• •

  Send quality outreach. Use personalization at scale, low sending limits, and multichannel outreach tactics to build real relationships.

• •

  Write subject lines that earn the open: short (under 50 characters), specific to the recipient, and free of spam trigger words. Use your preview text as a second chance, then test variations against each other and keep the winner.

Key takeaways

Alright y’all, that’s a wrap. To sum it up:

• •

  Apple Mail Privacy Protection fakes most of your opens, so open rate can no longer tell you who read your email.

• •

  Stop tracking open rates to increase deliverability and land in the primary inbox.

• •

  Start tracking inbox placement and domain reputation, and fix problems before they spread.

• •

  Close more deals by watching the signals that show real interest: reply quality, meetings booked, pipeline, and revenue.

Over to you

Cold email open rate was never a perfect metric. Now, with Apple Mail Privacy Protection faking nearly two-thirds of tracked opens, it’s actively misleading. Chasing a higher open rate won’t fill your pipeline if your emails are landing in spam or if the “opens” are bots.

Shift your tracking to what actually matters: inbox placement, reply rate, bounce rate, and spam complaints. Those signals tell you whether your outreach is working.

If you want to see where your emails are landing before you scale, lemlist’s Deliverability Hub and inbox placement testing give you that visibility. And if you want a step-by-step walkthrough of building campaigns that generate business, check out our cold email masterclass.
