Transcript
- Lucas: You know that subscriber who hasn't opened an email in six months? The one you keep sending to, hoping they'll come back? Most marketers just let them sit there, but Warby Parker found that a structured reactivation sequence recovered twelve percent of their dormant list and added about four hundred fifty thousand dollars in revenue over six months. Luna: That's not nothing. And I bet the key wasn't just sending a 'we miss you' email. Lucas: Right, exactly. Warby Parker used a three-phase model. Phase one is a simple re-engagement offer—something like 'come back and get ten percent off.' They send that after sixty days of inactivity. Phase two, a week later, is more personalized: 'We noticed you liked our Blake frames—they're back in stock.' Phase three, after another week, is a final check-in: 'We hate to see you go, but we understand—click here to stay or we'll stop emailing.' Luna: So they give the subscriber control. I like that. And I assume they track who responds to which phase? Lucas: Absolutely. They segment the responders into a 'reactivated' group and then continue with normal campaigns. For non-responders after phase three, they suppress them—stop sending altogether. That protects their sender reputation and keeps engagement metrics high. Luna: And I've seen data that shows a single re-engagement email has an average open rate of only about fifteen percent, but a three-email sequence can push that to over thirty percent. The increase is real. Lucas: It's about frequency and timing. The first email is easy to ignore. The second one, if it's relevant and timely, catches attention. The third creates a sense of finality. Warby Parker's data shows that the second email in their sequence had the highest click-through rate—almost double the first. Luna: What about subject lines? Did they test anything specific? Lucas: They tested two approaches. One was curiosity-driven: 'We found something for you.' The other was more direct: 'Your discount expires in 3 days.' The curiosity line had a higher open rate, but the direct line had a higher conversion rate. So they ended up using the direct line in phase one and the curiosity line in phase two, to leverage both benefits. Luna: Smart. And I think a lot of marketers worry that sending too many re-engagement emails will increase unsubscribes. But the data shows that if you're sending to people who are already disengaged, the unsubscribe rate from a reactivation sequence is actually lower than from a regular campaign—because they've already mentally checked out. Lucas: That's a really good point. If someone hasn't opened in six months, they're not really a subscriber anymore. They're just a number on your list. A reactivation sequence either wins them back or cleans them out—both are wins. Luna: And it's better for your deliverability. Sending to a stagnant list can trigger spam complaints and hurt your sender reputation. So this isn't just about revenue—it's about list health. Lucas: Exactly. So if you're running a reactivation sequence, what's the ideal timing? Warby Parker uses sixty days of inactivity before starting. But I've seen some brands use ninety days, and others use thirty. What's your take? Luna: I think it depends on your send frequency. If you email once a week, sixty days of no opens is about eight to nine emails ignored. That's a strong signal. If you email daily, you might move to thirty days. But the key is to define 'inactivity' as no opens, not no clicks—because someone might read your email without clicking. Lucas: Good distinction. And what about the offer? Do you think a discount is necessary? Luna: Not always. If your email content is valuable enough—like a newsletter with exclusive insights—you can win people back with a simple 'we've improved our content' message. But for ecommerce, a discount is usually the strongest lever. Warby Parker's ten percent off is modest but effective. You don't need to give away the farm. Lucas: I agree. And one thing I'd add is that the reactivation sequence should be a separate automation, not part of your regular send. That way you can track its performance independently and make adjustments without affecting your main campaigns. Luna: If these marketing conversations have sparked something you've actually used—like a reactivation sequence you've built or a test you've run—a couple of dollars a month is genuinely what keeps these shows going. It's at buy me a coffee dot com slash fexingo, if you've gotten something out of them. Lucas: Yeah, it really does make a difference. And we appreciate every bit of support. So back to reactivation—once you've set up the sequence, how do you measure success? Luna: I look at three metrics: reactivation rate—the percentage of dormant subscribers who open or click within the sequence; revenue per reactivated subscriber over the next sixty days; and list cleanup rate—how many were suppressed. If your reactivation rate is below ten percent, your offer or timing probably needs work. Lucas: And if it's above thirty percent, you might be waiting too long to start the sequence. You want to catch them before they fully disengage, but not so early that you're bothering active subscribers. Luna: Right. One more thing: after you reactivate someone, treat them like a new subscriber for the first few weeks. Send them a welcome-back series that re-familiarizes them with your brand. Don't just dump them into your regular daily emails. Lucas: Great advice. So to wrap it up: define inactivity based on opens, use a three-email sequence with a modest offer, test subject lines for different phases, and measure reactivation rate and downstream revenue. The goal isn't just to wake people up—it's to keep them engaged long-term. Luna: And clean your list of the ones who don't respond. It's better to have a smaller, engaged list than a large, dead one. Lucas: Exactly. That's the takeaway for this episode. We'll be back next time with another actionable strategy.
