Latest / The Retention Marketing Podcast with Fexingo: Email, SMS, and Loyalty for Repeat Customers / How a Supplement Brand Uses Email to Boost Repeat Purchases in 2026
Transcript
- Lucas: If you run a DTC brand, you know the math: acquire a customer for fifty dollars, hope they buy again, and pray the lifetime value covers your ad spend. But the brands that actually move that repeat rate tend to have one thing in common — a deliberate, timed post-purchase email sequence. Luna: And yet so many brands just send a 'thank you' and then go silent for weeks. That's a missed opportunity. Lucas: Exactly. Today I want to look at a supplement brand called Nourish+. They're a mid-size player — not a household name — but they saw a 28 percent increase in repeat purchase rate over six months, and they did it almost entirely through email. Luna: Twenty-eight percent is significant. What was their approach? Lucas: They built a three-email post-purchase sequence. Not a newsletter blast — a triggered, behavior-based series. Email one goes out on day five: 'how to use your product.' It's educational, not salesy. Email two on day fourteen: 'how are you feeling?' — a results check-in with a link to a short survey. And email three on day thirty: a replenishment reminder with a dynamic product recommendation based on what they originally bought. Luna: So they're mapping the customer journey after the first purchase, not treating every email the same. Lucas: Right. And here's the smart part: the replenishment email used a simple logic — if the customer bought a thirty-day supply of the greens powder, the email recommended the same product with a 'subscribe and save' option. But if they bought a one-time trial size, the email suggested the full size, not just a reorder. Luna: That kind of dynamic content requires some setup, but it's not rocket science. Most email platforms can handle conditional logic. Lucas: Absolutely. Nourish+ uses Klaviyo, which makes that kind of segmentation straightforward. But the key was the timing. They tested sending the replenishment email on day twenty-one versus day thirty. Day thirty won by a wide margin — a 41 percent click-through rate versus 22 percent. Luna: Wow. That's double. It makes sense though — if you send it too early, the customer still has product left. Too late, they might have already bought from a competitor. Lucas: Exactly. And this is where supplement brands have an advantage: the consumption cycle is predictable. You know when they'll run out. But the same logic applies to any product with a natural repurchase cadence — coffee, skincare, pet food, even office supplies. Luna: So what about the check-in email on day fourteen? Did that drive conversions directly? Lucas: Not directly. Its job was to build engagement and collect data. About 12 percent of recipients clicked the survey link. Nourish+ used that feedback to improve their product descriptions and even reformulated one product based on consistent complaints about taste. But the real conversion driver was the day-thirty email — that's where they saw the 41 percent click rate. Luna: And that click rate translated into actual purchases? Because click-through is one thing, conversion is another. Lucas: Fair point. Of those who clicked, about 34 percent completed a purchase. So overall, the sequence converted roughly 14 percent of recipients into repeat buyers. And that's on top of any other marketing they were doing. Luna: Fourteen percent from a single email sequence is solid. And when you consider that those are customers who might have otherwise churned — it's a direct lift to LTV. Lucas: Exactly. And Nourish+ didn't stop there. They also added a loyalty program enrollment prompt in the day-five email — 'create an account to earn points.' That alone boosted loyalty signups by 18 percent. It's a small tweak, but it compounds. Luna: I love that they integrated loyalty enrollment into an existing email rather than sending a separate, possibly ignored, message. Lucas: It's a lesson in respecting the customer's attention. One email, one purpose — but with a secondary nudge that feels natural. Luna: This kind of content — specific, actionable examples — is exactly why people listen. If these conversations have sparked something you've actually used in your own marketing, that's the whole point. Lucas: Yeah, we hear from listeners who say they've adapted a tactic from the show and seen real results. That's what keeps us going. A couple of dollars a month is genuinely what keeps these episodes ad-free and accessible — buy me a coffee dot com slash fexingo, if you've gotten something out of them. Luna: It's a small thing that makes a big difference. And we really appreciate it. Lucas: So back to Nourish+. One thing I found interesting: they also tested a 'win-back' email for customers who didn't open any of the three post-purchase emails. That email went out on day forty-five with a 15 percent discount code. Luna: And how did that perform? Lucas: It recovered about 5 percent of the non-openers. Not huge, but it paid for itself. The discount reduced margin, but those customers had a higher lifetime value over the next six months than the control group who got no win-back. Luna: So the discount didn't train them to wait for discounts? That's a common fear. Lucas: Nourish+ tracked that. They found that customers who redeemed the win-back discount did not have a lower subsequent purchase rate compared to customers who bought at full price in the same period. The key was that the discount was one-time, not a permanent offer. Luna: That's good data. So many brands are afraid to offer discounts to win back customers, but if it's a one-off, it seems safe. Lucas: Right. The rule of thumb is: never offer a discount that becomes the expected price. Make it a clear exception. Luna: Let's talk about the metrics they tracked. Beyond repeat purchase rate, what else did they monitor? Lucas: They looked at email engagement rates, obviously. But also average order value on repeat purchases — which actually increased by 8 percent over the six months, suggesting that customers who came back via email tended to buy more than their first order. And they tracked unsubscribe rate, which stayed under 0.5 percent for the sequence. Luna: So the emails were relevant enough that people didn't feel spammed. Lucas: Exactly. And the lesson for any brand is: start with a simple three-email flow. Day five, day fourteen, day thirty. Test your timing, test your offer, make it personal. You don't need a complex AI model to see a lift. Luna: I think a lot of marketers feel like they need to build the perfect automation from day one. But Nourish+ started simple and iterated. Lucas: That's the takeaway. Start. Measure. Improve. The 28 percent repeat rate increase didn't come from a single brilliant idea — it came from a series of small, data-driven tweaks. Luna: And now they have a baseline. They can keep optimizing. Lucas: Right. So if you're running a DTC brand, or even a service with a natural repurchase cycle, take a look at your post-purchase email flow. If you don't have one, that's your biggest opportunity. Luna: I'll definitely be checking my own flows after this. Lucas: Same. Thanks for listening, and we'll talk next time.
