Latest / The Email Marketing Podcast with Fexingo: Newsletters, Open Rates, and Subscriber Growth / Why Email List Re-Engagement Campaigns Recover Lost Subscribers
Transcript
- Lucas: You've got a list of fifty thousand subscribers. You send a campaign, and maybe twelve thousand open it. The other thirty-eight thousand — silence. Not a click, not a complaint, just dead air. Luna: And that dead air is actually hurting you, right? Because internet service providers see low engagement and start routing your emails to spam. Lucas: Exactly. It's called the engagement penalty. If you keep mailing people who never open, your sender reputation takes a hit, and your deliverability to active subscribers suffers too. Luna: So what's the fix? You can't just delete a third of your list. Lucas: You can, but you don't have to start there. The smarter move is a re-engagement campaign — a targeted sequence aimed at dormant subscribers, designed to either wake them up or let them go. Luna: I've seen these called 'win-back' or 'reactivation' campaigns. How do they actually work in practice? Lucas: Let's use a concrete example. There's a mid-size e-commerce brand — sells outdoor gear — that I worked with last year. They had about forty thousand subscribers, and roughly fifteen thousand hadn't opened an email in ninety days. Luna: That's a big chunk. Thirty-seven percent. Lucas: Right. They created a three-email re-engagement sequence. Email one: a simple 'We miss you' with a ten-percent discount. Email two, sent five days later: a subject line that asked 'Still interested?' with a link to update preferences. Email three, another five days: a final notice that they'd be moved to a low-engagement segment unless they clicked. Luna: And what happened? Lucas: Twelve percent of those dormant subscribers clicked. Some took the discount, some just updated preferences, but they re-engaged. The remaining eighty-eight percent were moved to a separate suppression list — essentially a sunset segment that they only mail quarterly now. Luna: So they didn't delete them, they just stopped mailing them as often. That's smart. Lucas: Exactly. The key number here: their overall open rate went from twenty-two percent to thirty-one percent within two months, because they stopped dragging down their metrics with dead addresses. Luna: That's a nine-point jump. And I bet their click-through rate improved too. Lucas: It did — from three percent to four point five. But the bigger win was deliverability. Their inbox placement rate, which had slipped to eighty-five percent, climbed back to ninety-four percent. Luna: Okay, so timing is clearly important. When do you define someone as dormant? Lucas: Industry standard is thirty to ninety days of no opens. For a daily newsletter, thirty days is probably enough. For a weekly or monthly brand email, I'd stretch to sixty or ninety. Luna: And what about people who never opened at all? Like, they signed up but never engaged? Lucas: Those are often called 'cold subscribers.' Some marketers send a re-engagement campaign straight away. Others include them in the normal sequence and let inactivity define the trigger. I'd argue the latter is cleaner — give them a chance to engage first. Luna: One thing I've seen work well is splitting the re-engagement into two tracks: a soft track and a hard track. Lucas: Yeah, I like that. Explain the soft track. Luna: Soft is basically a subject line change. Instead of 'We miss you,' you try something like 'Your next adventure starts here' or 'Did you see this?' You're not asking them to opt in again — you're just trying to catch their eye. Lucas: And the hard track? Luna: Hard track is the explicit 'Click here to stay subscribed' approach. If they don't click, you remove them after a set number of sends. It's more aggressive, but it's also more effective at cleaning your list. Lucas: Right. And the data supports both. Litmus did a study showing that re-engagement emails have an average open rate of about fifteen percent — higher than regular campaigns for that segment — but only if you've actually segmented them properly. Luna: Segmentation is everything. If you send the same re-engagement email to someone who hasn't opened in thirty days versus someone who hasn't opened in a year, you're wasting your shot. Lucas: Exactly. The thirty-day person might just need a better subject line. The one-year person probably needs a hard reset — maybe even a preference center link. Luna: And that's where the preference center becomes a re-engagement tool. Instead of just 'click to stay,' you offer frequency options: weekly digest, only sales, only blog posts. Lucas: I've seen that work really well. One B2B SaaS company I know sends a 'Take a break' option — subscribers can choose to pause emails for thirty days rather than unsubscribe. They recovered about eight percent of people who would have otherwise just left. Luna: That's clever. It's a softer ask than 'stay or go.' Lucas: Alright, let's talk about the actual copy. What makes a re-engagement email actually get clicked? Luna: I think the biggest mistake is being too apologetic. 'We're sorry for bothering you' — that just makes people feel guilty, not interested. Lucas: So what's the right tone? Luna: Curious and helpful. Something like 'We noticed you haven't opened lately — is there something we can do better?' That invites feedback, which is valuable. Lucas: And include a clear call to action. Don't give them five options. One primary action — click to stay, click for a discount, or click to update preferences. Luna: How many emails in the sequence? Three seems common, but I've seen sequences as long as five. Lucas: Three is usually enough. Any more and you risk annoying the people who do want to stay. The cadence should be spaced out — five to seven days between each. Luna: And what about the final email? Should it be a 'goodbye'? Lucas: Some marketers send a final 'We're sorry to see you go' email. I'm mixed on that. If they haven't opened any of the previous three, they probably won't open that one either. Better to just move them to the suppression list. Luna: If these conversations have sparked something you've actually used in your own email strategy — maybe you tried a re-engagement sequence or cleaned up a dormant segment — honestly, if today was worth a coffee to you, that's the link: buy me a coffee dot com slash fexingo. Lucas: Yeah, it's a small way to keep the show ad-free and focused on practical tactics like this. Appreciate anyone who feels inclined. Luna: Okay, back to the numbers. One metric I think gets overlooked in re-engagement is the 'non-open rate' trend over time. If you run a campaign and see open rates improve but non-open rates stay flat, you might not have actually cleaned your list. Lucas: That's a great point. You want to see the absolute number of dormant subscribers shrink, not just the percentage. Because if you only look at percentages, you might be fooled by new subscribers joining. Luna: Exactly. So track the raw count of people who haven't opened in ninety days. That's your true north. Lucas: Alright, let's wrap with one tactical tip. After you run a re-engagement campaign, set up an automated rule: any subscriber who hasn't opened in ninety days gets flagged for the next re-engagement cycle. Make it ongoing. Luna: Don't just do it once. It should become part of your email operations. Lucas: Exactly. Because list fatigue is inevitable. People change jobs, change interests, change inbox habits. A quarterly re-engagement sweep keeps your list healthy year-round. Luna: And your sender reputation thanks you.
