Latest / The Email Marketing Podcast with Fexingo: Newsletters, Open Rates, and Subscriber Growth / Why Your Email List Is a Living Organism
Transcript
- Lucas: You know, I was going through some old campaign reports the other day, and it struck me that we tend to talk about email lists like they're spreadsheets. Rows and columns of addresses, churn percentages, growth rates. But the more I look at the data, the more I think we're missing something fundamental. Luna: What are we missing? I'm guessing you're not about to tell me the list is sentient. Lucas: Ha, not sentient, but close. I think the best mental model for an email list is a living organism. It's born, it grows, it goes through phases of activity and dormancy, and it can even die if you don't feed it properly. And once you see it that way, all the tactics we've talked about on this show—segmentation, pruning, re-engagement—start to look different. Luna: So you're saying we should treat subscribers less like contacts and more like, what, houseplants? Lucas: Exactly. Some need more sun, some need less water, and some are just dormant waiting for the right season. I came across a study this summer from a marketing analytics firm that looked at hundreds of brands. They found that re-engaging just five percent of dormant subscribers lifted overall revenue by twelve percent. That's not a rounding error. Luna: Twelve percent from five percent of the list? That's huge. But how do you define dormant? Is it just no opens in ninety days? Lucas: Right, that's the typical cutoff, but the organic model says it's more nuanced. A subscriber might be dormant for a while, then come back when you launch a new product or send a survey. The point is, dormancy isn't death. It's a stage. And if you treat it that way, you stop spending all your energy on pruning and start thinking about revival. Luna: So what's the first step to thinking like a gardener instead of a janitor? Lucas: Start by mapping your list's lifecycle. Every subscriber is in one of four stages: active, engaged, at-risk, or dormant. Active means opening and clicking regularly. Engaged might open but not click. At-risk is when they start to slip—opens drop off for a month or two. Dormant is, well, the long silence. Luna: And you'd treat each stage differently, I assume? Lucas: You have to. A one-size-fits-all campaign is like watering every plant the same amount. Some drown, some dry out. For active subscribers, you send them your best stuff and ask for referrals. For engaged, you maybe test different content formats to push them to click. At-risk, you might reduce frequency before they tune out completely. And dormant is where the lifecycle-specific re-engagement flows come in. Luna: I've seen those 'we miss you' emails, but they often feel a bit... desperate. Lucas: That's because most brands send one and then give up. The organic model means you plan a sequence. Maybe the first email is a value-add, a piece of content they haven't seen. The second could be a survey asking what they're interested in. The third might be a last-chance offer. And then, if they're truly dormant, you let them go—but you do it with a graceful exit, not a guilt trip. Luna: That's a great segue to something I've been thinking about. We often talk about list growth, but growth is just the birth rate. What about the death rate? How do you reduce it? Lucas: Well, the first thing is to stop buying or renting lists. I know that sounds obvious, but a lot of brands still do it, and it's like introducing invasive species into a delicate ecosystem. The subscribers you earn through co-registration or double opt-in are the ones that are actually alive and interested. Luna: Right, and we've talked about co-registration before. But what about the idea of progressive profiling? I've been reading that asking for more info over time, rather than at signup, keeps engagement higher. Lucas: Yes, and that fits perfectly with the lifecycle model. When someone first signs up, they're in the 'infant' stage. You don't ask them for their job title, company size, and favorite color. You build trust first. Then, with each email they engage with, you can ask one small piece of information. That's how you learn what they want from you—and that's what keeps them active. Luna: So it's like growing a relationship, not just a database. Lucas: Exactly. And once you think about it that way, you stop obsessing over total subscriber count. That's just the population, not the health. The metric that matters is active engagement rate—the percentage of your list that's opened or clicked in the last ninety days. That's like measuring the pulse of your organism. Luna: And how do you actually measure that? Is there a standard formula? Lucas: There isn't a universal one, but a simple version is: number of unique subscribers who opened or clicked in the last ninety days, divided by total subscribers, times one hundred. You can tweak the window, but the key is to track it over time. If your active engagement rate is trending down, your list is dying, even if your subscriber count is going up. Luna: That's a sobering thought. I bet a lot of marketers would be surprised to see their real number. Lucas: Which is why the next step is to audit your list. Pull a report of everyone who's been dormant for six months or more. Chances are, it's a bigger chunk than you think. And then, instead of just deleting them, run that re-engagement sequence we talked about. You might be surprised how many come back. Luna: I actually have a small example from my own inbox. There's a newsletter I subscribed to ages ago, and I never opened it. Then last month, they sent a 'What do you want to learn about?' survey, and I actually replied. Now I read every issue. Lucas: That's the lifecycle in action. They gave you a way to signal your interests, and you went from dormant to active. That's the kind of thing we're talking about—creating a chance for revival rather than just deletion. Luna: So for someone listening who wants to apply this tomorrow, what's the single most important takeaway? Lucas: I'd say: start viewing your list as a series of relationships, not a static asset. And then let that mindset drive your campaigns. You'll find that you naturally send more relevant emails, you'll feel okay about letting some subscribers go, and you'll see better returns from the ones who stay. Luna: If today was actually useful to you, the way these stay ad-free is listener support — buy me a coffee dot com slash fexingo. Lucas: Yeah, it's a small gesture that keeps the podcast going. And every bit helps. Luna: Alright, back to the lifecycle. You mentioned you were going through old campaign reports. What did you find that sparked all this? Lucas: I was looking at a client's list from two years ago. They had seventy thousand subscribers, but the active engagement rate was under fifteen percent. They were celebrating the size, but most of those people were just... not there. We ran a re-engagement flow, and surprisingly, we brought back about eight percent of the dormant segment. That alone added a meaningful chunk to their monthly revenue. Luna: So what happened to the other ninety-two percent that didn't come back? Lucas: We gave them a final 'we'll miss you' email with a one-click unsubscribe. The list shrank, but the deliverability improved because the engagement rates went up across the board. And that's the thing—a smaller, healthier list often outperforms a big, bloated one. Luna: It's like the idea of quality over quantity, but for email lists specifically. Lucas: And there's a tangible reason. ISPs, like Gmail and Outlook, look at your engagement rates when deciding whether to put you in the promotions tab or the spam folder. A lower active engagement rate hurts your sender reputation. So by purging the dead weight, you're actually improving your chances of landing in the inbox for the people who want to hear from you. Luna: That's a great point. And I've noticed that we haven't talked about the role of content in this organic model. If the list is a living thing, what's the food? Lucas: Content is absolutely the nourishment. But it's not just about sending more—it's about sending the right kind. For active subscribers, you can send them deeper dives or case studies. For engaged ones, maybe you test listicles versus long-form. The idea is to feed each segment what keeps them growing. Luna: So it's like a custom diet for each subscriber group. Lucas: Exactly. And you know what, there's a tool that can help with this: engagement scoring. You assign points for opens, clicks, replies, even survey responses. Then you can automate the lifecycle stages. If a subscriber's score drops below a threshold, they move to 'at-risk' and trigger a different flow. Luna: That sounds like a lot of setup, but I can see how it pays off in the long run. Lucas: It does, but you don't have to build the whole thing at once. Start with a simple scoring system: one point for an open, two for a click, three for a reply. Then set a threshold for 'dormant'—say, a score of zero for ninety days. That's enough to get started. Luna: I think the organic metaphor really helps make it concrete. I'm already thinking about my own list in terms of, like, which subscribers are in the 'vegetative state'. Lucas: Ha, exactly. And sometimes you need to pull the plug. But the point is, you do it deliberately, with a chance for revival, not just because you feel like pruning. Luna: So, let's say someone's listener takes this to heart. What's the one thing they should do this week? Lucas: I'd say, run your active engagement rate today. Just calculate it, and see where you stand. Then, if it's below thirty percent, you know you've got work to do. That's the starting point for the lifecycle approach. Luna: And next week, we could talk about how to actually use that score to segment your list for a re-engagement flow. Lucas: Sounds like a plan. For now, think of your list as a garden. It needs regular care, the right nutrition, and a little patience. But the harvest can be a lot more rewarding than you think.
