Latest / The Email Marketing Podcast with Fexingo: Newsletters, Open Rates, and Subscriber Growth / The Silent Killer of Email Deliverability
Transcript
- Lucas: If you have been checking your email dashboard this week, you might have noticed something weird. Your open rates are either skyrocketing or plummeting for no obvious reason, and the subject line tests don't explain it. Luna: Right, because I just ran a campaign where the open rate hit forty percent on a segment that hasn't opened anything in six months. It felt like a glitch. Lucas: It isn't a glitch. It is the new normal for late September twenty twenty-six. We talk a lot about personalization and automation, but we rarely discuss the invisible infrastructure that is currently breaking our data. The problem is third-party tracking pixels. Luna: You mean those tiny one-by-one-pixel images we embed in emails to count when someone opens them? Lucas: Exactly. For years, that pixel was the gold standard for measuring engagement. When an email loads, the pixel fires, the server logs it, and you get a green light in your report. But major email providers have fundamentally changed how they handle these requests. Luna: So the pixel fires even if the user never sees the email? Lucas: Yes. Apple introduced Mail Privacy Protection a few years ago, and by now, it is not just Apple. Google has rolled out similar zero-click rendering features across Gmail for business and personal accounts. When your email hits an inbox that supports these privacy shields, the system pre-fetches all content, including those tracking pixels, before the user even looks at the message. Luna: That means your forty percent open rate is basically a measurement of how many people have privacy settings enabled, not how many read your content. Lucas: Precisely. And here is the dangerous part. Most marketers use open rates as a proxy for health. If opens drop, they tweak subject lines. If opens spike, they assume success. But with privacy shielding, that signal is completely broken. You are optimizing for a metric that no longer reflects human behavior. Luna: And what happens when you optimize for a broken metric? You waste budget on strategies that don't actually move the needle. Lucas: Right. So let's look at the actual mechanics. When a privacy shield pre-fetches your email, it sends a request from an Apple or Google proxy IP address. Your email service provider logs that as an open. But critically, it also creates noise in your domain reputation signals. Luna: How does fake open data hurt your domain reputation? I thought ISPs only cared about spam complaints and bounces. Lucas: They care about engagement patterns. ISPs analyze how users interact with your mail. If you suddenly see a massive spike in opens that correlates with low clicks or zero conversions, it looks like bot traffic or artificial inflation. Major ISPs like Yahoo and Microsoft are increasingly sophisticated. They can detect when open rates diverge sharply from click-through rates. Luna: So if everyone has high opens but low clicks because the pixels are firing automatically, the ISP thinks you are sending irrelevant junk. Lucas: Spot on. They might throttle your delivery or push you into the promotions tab, which is effectively the graveyard for transactional and marketing emails. The irony is that by trying to prove your email is relevant via open rates, you might be accidentally proving it is not. Luna: This feels like we need to stop using open rates entirely. Is that feasible for most businesses? Lucas: It is not just feasible; it is necessary. The question is what do you replace it with? Click-through rate is much harder to fake. A user has to intentionally decide to click a link. That requires cognitive effort and interest. It is a far stronger signal of genuine engagement. Luna: But click-through rates are usually so low. People say two percent is average. How do you celebrate progress when the numbers are that small? Lucas: You focus on the quality of the click, not the volume. Look at post-click conversion rates. Did the click lead to a purchase, a sign-up, or a download? That is the metric that matters for revenue. Open rate is a vanity metric. Conversion rate is a business metric. Luna: So we should audit our dashboards and hide the open rate column? Lucas: I would go further. Hide it from leadership. Keep it for historical comparison if you want, but stop making strategic decisions based on it. Instead, track unique clicks, unsubscribe rates, and spam complaint rates. These are the signals that ISPs actually respect. Luna: Unsubscribe rates seem like a negative indicator. Why is that a good signal? Lucas: Because it shows honesty. If someone unsubscribes, they are telling you directly they don't want your content. That is valuable data. It helps you clean your list. A clean list with fifty thousand engaged subscribers is worth infinitely more than a bloated list of five million people who never open your emails. Luna: List hygiene is definitely a recurring theme for us. But this goes deeper than just cleaning addresses. It's about trusting the tech stack less. Lucas: Agreed. We need to accept that we are flying blind on the top of funnel visibility. We used to know exactly who opened what. Now we only know who acted. That is a smaller pool, but it is a real one. Luna: Do you think other platforms will follow Apple and Google's lead on blocking tracking? Lucas: It is already happening. Microsoft is tightening controls, and various privacy regulations globally are pushing for stricter opt-in requirements for data collection. The era of passive tracking is ending. Marketers who adapt to active consent models will win. Luna: Active consent. That sounds expensive and labor-intensive to implement. Lucas: Not necessarily. It means shifting your mindset. Instead of asking how many people saw your email, ask how many people chose to engage with it. That changes your creative strategy too. You stop writing clickbait subject lines designed to trick the pixel and start writing compelling content designed to drive action. Luna: So better copy, better offer, clearer call to action. Less worrying about the little tracker image. Lucas: Exactly. And here is a practical tip. Remove the tracking pixels from your newsletters if possible. Many modern email platforms allow you to disable them. You lose the open count, but you gain cleaner data and better deliverability. Luna: I had no idea you could turn them off. I always assumed they were mandatory for any professional email. Lucas: They used to be. Now they are optional. In fact, some experts argue that removing them signals trust to the recipient. You aren't spying on them. You just want them to read your message. Luna: That is a bold brand stance. I like it. But back to the data. If we ignore opens, how do we segment our audience anymore? Lucas: You segment based on behavior. Did they click the product link? Did they visit the blog post? Did they make a purchase? Those are behavioral segments. They are dynamic and predictive. Open-based segments are static and misleading. Luna: Behavioral segmentation is definitely more powerful. It lets you target people based on intent rather than just curiosity. Lucas: Intent is everything. In September twenty twenty-six, intent is the only currency that matters for email marketers. Curiosity is dead. Luna: Okay, before we dive deeper into behavioral triggers, I want to pause for a second. Lucas: Sure. Luna: If these conversations about fixing your email infrastructure have helped you rethink your approach, or if you've started stripping out those tracking pixels, we'd love to hear from you. Lucas: We keep this network ad-free and independent. It runs on listener support. If you find value in these deep dives, consider supporting us monthly at buy me a coffee dot com slash fexingo.

It keeps the content focused on what actually works for your business. Lucas: Thank you for being part of this community. Now, let's get back to the behavioral segmentation model. Luna: Right. So if we are moving away from open rates, what is the first step to implementing behavioral segmentation today? Lucas: Audit your current goals. Are you celebrating opens in your weekly reports? Stop. Start celebrating clicks. Then, map out the customer journey. Identify three key actions a subscriber takes after receiving an email. Luna: Like clicking a link, downloading a resource, or adding to cart? Lucas: Exactly. Create automated workflows that trigger based on those actions. If they click but don't buy, send a reminder. If they buy, send a thank you. If they do nothing, wait. Let their silence tell you they aren't ready yet. Luna: That feels much more respectful of the user's time. It stops the barrage of generic reminders. Lucas: It does. And it improves deliverability because you are sending targeted content to engaged users. ISPs see higher engagement rates, and your inbox placement improves. Luna: So privacy protections and better segmentation work together. They force us to be smarter, not just louder. Lucas: Precisely. The technology is forcing a return to fundamental marketing principles. Know your customer, provide value, respect their attention. Luna: It is interesting that a limitation in tracking leads to better creativity. I hadn't thought of it that way. Lucas: Constraints often breed innovation. When you can't rely on data tricks, you have to rely on good storytelling. Luna: So the next time your open rate looks weird, don't panic. Just assume your audience is protecting their privacy and focus on the clicks. Lucas: Assume the best, optimize for the click, and let the rest be noise. That is the new playbook for email marketing in the privacy age.
