Transcript
- Lucas: If these marketing conversations have sparked something you've actually used, remember that small listener support keeps this show running ad-free. Luna: Yeah, just a couple of dollars a month makes a real difference for the team behind the mic. Lucas: You can help us out at buy me a coffee dot com slash fexingo if you want to keep the lights on. Luna: Thanks for supporting independent journalism like this. Lucas: Let's get back to it. We talk a lot about list growth, list health, and list segmentation here, but I think we’ve been ignoring the elephant in the inbox: fatigue. It’s September first week of 2026, and if you look at the aggregate data from major ESPs, the average consumer is receiving roughly twelve marketing emails per day. That is up significantly from five years ago. Luna: Twelve? That feels high even for someone deep in the industry, but I can see how the algorithmic pushback would feel overwhelming to the average person. Lucas: It is high, and it’s dangerous. The problem isn't that people are deleting emails faster; it’s that they are psychologically tuning them out before they even open them. We call it 'banner blindness' in display ads, but in email, it’s 'subject line blindness.' When your audience expects noise, they stop listening for signal. Luna: So you're arguing that our obsession with frequency metrics is actively degrading the value of every single send we make? Lucas: Exactly. And here is the concrete case study that changed my mind about this. There was a mid-sized B2B SaaS company, let's call them CloudSync, that had a newsletter going out three times a week. Engagement was plateauing, so their CMO decided to cut frequency to once a week for two months. Luna: That sounds like a bold move during a quarter where most boards are pushing for maximum top of funnel volume. Lucas: It was terrifying for them too. But what happened next is counterintuitive. Open rates didn't drop; they stabilized. Click-through rates went up by eighteen percent. And most importantly, unsubscribe rates dropped to near zero. They weren't losing subscribers because they sent less; they were keeping them because they respected their time. Luna: That eighteen percent lift in clicks is huge. It suggests that when people do open, they are actually reading, rather than just scanning for a link to dismiss. Lucas: Right. Because cognitive load is finite. When you bombard someone with daily updates, they treat your email like junk mail. When you give them a weekly digest, they treat it like a newspaper. The perceived value goes up simply because the scarcity increases. Luna: But doesn't that risk fading memory? If you only show up once a week, aren't you risking being forgotten in a crowded inbox? Lucas: That is the classic fear, but the data from CloudSync showed otherwise. Their click to conversion rate actually improved because the audience was warmer. They weren't cold leads anymore; they were engaged readers waiting for the next insight. In fact, their trial sign-ups went up twenty-two percent despite sending sixty percent fewer emails. Luna: So the quality of the interaction outweighed the quantity of the touchpoints. It’s basically the difference between a friend texting you all day versus calling you once a week. Lucas: Precisely. And it’s not just B2B. Look at retail. Major apparel brands are seeing similar patterns. When they shift from daily promotional blasts to curated weekly drops, the average order value actually rises. Why? Because the buyer has more time to deliberate, and they perceive the selection as more exclusive. Luna: I love that angle. Exclusivity through scarcity. It flips the script on the traditional 'more is better' marketing dogma. Lucas: It does. But implementing this requires a cultural shift in how teams measure success. Most marketing departments still track 'total impressions' or 'total sends' as vanity metrics. You need to start tracking 'engagement depth' instead. Luna: What does engagement depth look like in practice? Is it just clicks, or are we looking at time spent reading? Lucas: It’s deeper than that. Look at scroll depth within the email client. Look at reply rates. A high reply rate indicates a human connection, which is the holy grail of combating fatigue. Also, watch your spam complaint rate closely. Even a tiny uptick there is a leading indicator of severe fatigue. Luna: Spam complaints are the ultimate vote of no confidence. If one person marks you as spam, you lose that user forever, and you hurt your sender reputation with the ISP. Lucas: Correct. And sender reputation is tied directly to your IP address and domain authority. If you burn out your list, your deliverability suffers. It’s a vicious cycle: you send more to compensate for low opens, which causes more fatigue, which causes lower opens, forcing you to send even more. Luna: That trap is so easy to fall into when you’re under pressure to show quarterly growth numbers. Lucas: It is. But here is the actionable part for our listeners. First, audit your current frequency. If you are sending daily, try cutting to every other day for a month. Monitor the metrics. Second, implement a preference center that lets users choose their own cadence. Luna: Letting the user opt-in to frequency is smart. It gives them control and reduces the feeling of being harassed. Lucas: It does. And third, focus on content density. If you send less, each email must deliver more value. No fluff. No generic 'hope you are well' intros. Get straight to the insight, the deal, or the update. Respect the reader’s time, and they will respect your brand. Luna: Content density over volume. That’s a mantra worth writing down. It shifts the focus from logistics to creativity. Lucas: Exactly. Creativity thrives under constraints. When you can’t rely on volume to wash over the audience, you have to make every word count. Luna: Do you think ai generated content exacerbates this fatigue? It feels like everyone is spewing generic, optimized text now. Lucas: Absolutely. AI can help with drafting, but if you use it to generate bulk volume without human oversight, you are adding to the noise. Audiences are getting smarter at detecting soulless, mass-produced content. Authenticity is becoming a premium feature. Luna: So the solution isn't to fight AI, but to use it to enhance personalization rather than just scaling mediocrity. Lucas: Yes. Use AI to segment better, to predict optimal send times, but keep the voice human. Keep the message specific. One concrete takeaway for you today: check your last thirty sends. If any of them felt redundant, delete the template. Don't send again unless you have something new to say. Luna: Delete the template. That’s a powerful directive. It forces discipline. Lucas: Discipline is what separates good marketers from great ones. Great ones know when to stay quiet. Luna: I agree. Silence can be loud if it builds anticipation. What’s the biggest mistake you see companies making when they try to combat fatigue? Lucas: The biggest mistake is re-engagement campaigns that are actually just more noise. Sending 'We miss you!' emails to inactive users who haven’t opened in six months is annoying. It reminds them they forgot you, which reinforces the forgetfulness. Luna: Right. Just guilt-tripping them into opening an email they don’t care about. Lucas: Exactly. Instead, clean the list. Archive the inactive users. Focus your energy on the active ones. It’s better to have ten thousand engaged readers than one hundred thousand ghost subscribers. Luna: Clean lists, higher engagement. It’s a simpler model, but it requires letting go of ego-driven vanity metrics. Lucas: It does. And in 2026, with privacy regulations tightening and inbox providers getting smarter, that simplicity is your best defense. Algorithms favor engagement, not volume. Luna: So the future of email marketing is quieter, sharper, and more respectful. It’s a welcome change from the shouting matches we’ve seen in previous decades. Lucas: I think so. It brings the medium back to its roots as a direct, personal communication tool. Not a broadcast megaphone. Luna: I wonder if we’ll see a return to handwritten-style notes in digital form as a way to stand out in the quiet. Lucas: Maybe. Or just really good curation. Whatever it is, the brands that listen to their audiences will win. The question is, are you listening enough to hear when they need a break?
