Why You're Wrong About Emailing Your Subscribers: The Billing Reminder Playbook (With Brice Douglas, Zaymo)

Why most brands are wrong about emailing their subscribers

If you've spent any time in subscription DTC, you've heard the rule: don't email your active subscribers, you'll remind them they're being billed and they'll churn.

It sounds intuitive. It's also costing brands millions in incremental revenue every year.

I've written about this misconception before in our Retention Marketing Strategy Bible and again in our 4-Play LTV Upsell Playbook, but I wanted to go properly deep on the data behind it. So I sat down with Brice Douglas, CEO and co-founder of Zaymo — the interactive email platform that lets subscribers swap products, change frequencies, and upgrade plans directly inside the inbox, without ever logging into a portal.

What makes Brice's perspective unusually sharp is what Zaymo sees in the data. They run holdout tests across dozens of DTC subscription brands every month, isolating the impact of specific message types on cancellation rate and long-term LTV. So when he tells you a billing reminder doesn't cause churn, he's not theorising. He's measuring.

What came out of the conversation is, in my view, the most important data point in subscription marketing right now. Below is the full breakdown including Brice's findings from the Zaymo data, and how I'd map each one back to the DTC retention strategy.

Do billing reminders cause subscriber churn?

This is the question every subscription brand wrestles with. Send the order-upcoming email and risk reminding people they're being charged. Don't send it and risk them forgetting your brand exists.

Most brands solve this by defaulting to silence. They reason that the worst outcome, i.e., an avoidable cancellation is worse than the missed upsell opportunity.

Brice's data tells you they're wrong on both counts: "Most of the time if you just send a billing reminder normally, you will cause a spike in churn," he told me. "But if you frame these communications in the right way, we've been able to see across our brands ways to completely mitigate that spike and also turn that communication into something positive."

The key word there is frame. A generic "your order ships Tuesday, you'll be charged $42" message is a churn risk. A reframed message that says "your order ships Tuesday — here's what you can change before it does" is a retention asset.

This maps almost exactly onto what we see on the email strategy side. The brands losing money on their subscriber base aren't losing it because they're communicating. They're losing it because they're communicating badly.

The play: Audit your order-upcoming email right now. If the dominant CTA is "manage your subscription" pointing to a portal, you're sending a churn flag. The dominant CTA should be a flexibility action — swap flavour, delay, accelerate, upgrade — that the subscriber can complete without leaving the inbox.

What does a billing reminder that doesn't cause churn actually look like?

Brice walked me through a holdout test his team ran for a popular coffee brand. The brand had been so worried about cancellation risk that they'd stopped sending order-upcoming emails entirely for several months. Zaymo proposed a controlled test:

• 50% of the subscriber base received no reminder (the status quo).
• 50% received a reminder reframed around flexibility — swap, delay, accelerate, upgrade, cross-sell — with the actions embedded directly in the email.

The result is the line that should be on a poster on every retention marketer's wall:

"The cancellation rate was actually exactly the same across the two cohorts," Brice said. "But when we measured LTV over time, first of all, using the opportunity as a cross-sell already added revenue. And then second of all, these customers who had a choice over their subscriptions of how to customise it for themselves were sticking around longer than the cohorts that didn't. The total spend across these was 10% higher across the entire cohort of people who did receive the reminder versus people who were kind of left to their own devices."

Same cancellation rate. 10% higher total spend.

The brand that sent nothing thought they were protecting LTV by staying quiet. They were leaking 10% of the value of their subscriber base by not showing up.

The Bite data point reinforces this. Bite — a fluoride-free toothpaste brand — ran an A/B test of a similar reframed billing reminder against a generic one. The flexibility-led version drove a 13% lower cancellation rate and a 50% increase in cross-sells from the same email send.

This is exactly the dynamic I covered in the 4-Play LTV Playbook, but the holdout-test data here is the proof. Subscribers aren't fragile. They don't need to be left alone. They need to be given a reason to engage that isn't "click here to cancel."

The play: Rebuild your order-upcoming email with four flexibility actions and one cross-sell. The four actions: swap product/flavour, delay the order, accelerate the order, change frequency. The cross-sell: one contextually-paired SKU — not a generic carousel. Every action should complete inside the inbox. We covered why pairing logic matters in our AOV cohort playbook with Ben Sharf — the same data-backed pairs apply here.

Why "too much product" is the number one driver of CPG subscription churn

This is the diagnostic insight I think most subscription brands underrate, and it explains why flexibility-led emails work so well.

"The number one reason for churn, if you kind of average all of direct-to-consumer CPG-type subscription brands, is having too much product," Brice told me. "On a software subscription, it makes sense to bill every month or every period consistently. But when you're talking about consumables, every user treats consumables a little differently. My neighbour across the street is going to shave more often than I am and going to need refills at a different rate."

Think about what that means for the standard subscription model.

The brand sets a default cadence — say, every 30 days. Half the customer base goes through the product faster than that and runs out. The other half goes through it slower than that and accumulates a backlog. Both halves have a problem. Only the second half churns visibly.

The customer with too much razor blades doesn't write a polite email asking to extend their cadence. They open the portal, see the cancel button, and click it. Because cancelling is one click and "change my frequency from every 30 days to every 45 days" is buried three menus deep.

This is precisely why embedding the swap/delay/frequency actions inside the order-upcoming email is so high-leverage. You're catching the "too much product" customer at the exact moment they're about to make the cancel decision — and giving them an easier alternative.

It maps directly onto what we obsess over on the retention side. Recency is the strongest predictor of repeat purchase, but recency is downstream of fit. A customer who feels the product is being forced on them at the wrong cadence is a customer who'll churn no matter how good your post-purchase flow is. Fix the cadence at the moment of friction, and the post-purchase flow has something to actually work with.

The play: Add a one-click "delay my next order by 2 weeks" action to every order-upcoming email. Make it visually equal to the swap and upgrade options — don't bury it. The customers who use it are the customers you would have lost. The customers who don't are the customers happy with cadence. Either way, you've protected the cohort.

When should you upsell and cross-sell your active subscribers?

If billing reminders don't cause churn, the obvious next question is when to push harder.

Brice identified two windows where upsells consistently outperform:

1. The order-upcoming email itself.

This is the most under-exploited high-intent moment in subscription DTC. Your subscriber is opening an email about a payment they are about to make. Their attention is on your brand, on their order, on their wallet. There is no higher-intent context in which to offer them something — whether that's an upgrade to a longer cycle, a complementary cross-sell, or a subscriber-only discount.

The classic upsell here is the cycle upgrade: monthly → quarterly → semi-annual → annual. As Brice put it: "Those offers for a lot of brands exist on the product page. But if you're capturing someone through Meta and they're interacting with your brand for the first time, a subscription is already a big ask. An even bigger ask is to commit quarterly here with us or commit annually. So we see the retention marketing side as a great lever to pull for people who already love your product."

This is the exact lever Loop's portal upsell play covered in our 4-Play LTV Playbook — but executed on the surface where subscribers actually spend their time. The portal play and the inbox play aren't competing. They're complementary. Some subscribers convert on the portal banner; the rest convert on the inbox prompt.

2. Product launches and special campaigns.

This is where brands lose the most money to the "don't email subscribers" myth. They run a new product launch to their prospect base, exclude their subscribers from the send, and then wonder why their existing customer base never adopts the new SKU.

"By sending these product launches or special offers to your subscriber base, your take rate can be extremely high," Brice said. "When we layer on Zaymo on top of that by embedding the CTA into the email with no redirect, we actually see a 50% higher take rate than using a Recharge or Stay AI quick link, for example. Same offer, same timing — 50% higher than that, which can be huge at scale."

That 50% lift is the single most important data point for anyone making the build-vs-buy decision on interactive email. The redirect leak — the gap between "I want this" and "I am in the portal completing it" — is where half the take-rate disappears.

The play: Include your active subscriber base in every product launch send. Layer a subscriber-only incentive on top (early access, exclusive bundle, 10–20% perk). If you have interactive email infrastructure, embed the action one-click. If you don't, this is the single highest-ROI place to invest first.

How to embed actions inside the email (and why redirect links underperform)

Most subscription brands assume the choice is binary: send a billing reminder with a "manage subscription" link, or send nothing at all.

That framing is what creates the false choice between churn risk and silence. The third option, i.e., embedding the actions inside the email itself is the one that breaks the trade-off.

Brice walked me through the Bite (toothpaste) example to make this concrete. In a single email, the subscriber can:

• Swap from mint to berry-twist flavour (one click, applies to next order)
• Delay the order by a week (one click)
• Upgrade to the full daily-habits kit with mouthwash and toothbrush at 10% off (one click, subscribes them to the larger bundle)
• Add affordable cross-sells like floss to the next shipment (one click, ships with the next order)

"It's so easy that we've had to add an undo button," Brice said. The point being: when the friction drops to one click, the customer changes their behaviour. They start curating their subscription instead of cancelling it.

Compare that to the traditional flow:

1. Open email
2. Click "manage subscription"
3. Land on portal login
4. Enter credentials
5. Navigate to subscription
6. Find the swap option
7. Select new flavour
8. Confirm change
9. Receive confirmation

Nine steps versus one. At every step, you lose a percentage of subscribers to friction, to forgotten passwords, to the customer reconsidering whether it's worth the effort. By step five, many customers see the cancel button and take that action instead because it's the one click in the whole flow that doesn't require thought.

Brice's holdout data on this: when his team A/B-tested identical email content with the only variable being embedded actions vs. redirect-to-portal links, the embedded-action version saw 20% lower attributed churn in the short term, with the LTV gap widening over time.

There's a deliverability and CRM design implication here that's worth flagging. Interactive email (AMP) only works in inboxes that support it primarily Gmail. For other inboxes, you need a graceful fallback to standard HTML. This is non-negotiable for any brand running it at scale. We covered the broader deliverability fundamentals in our Email Deliverability Bible — the same rules apply, with the added consideration that interactive content needs to degrade gracefully.

The play: Map every action in your current subscriber email flows by click-count-to-completion. Anything over two clicks is a leak. Prioritise embedding the highest-volume actions (swap, delay, accelerate, upgrade) inside the email. Track interaction events, not just click-through rate — traditional CTR understates performance when the action happens in-email.

How aggressively can you email churned subscribers?

This was the section of the conversation I didn't expect, and it's reshaped how I think about reactivation strategy.

Most brands run a churned-subscriber sequence of three to five emails over 30–60 days, then drop the contact into the broader list and effectively forget about them. The logic is sensible: you've already lost them, and over-mailing risks brand damage and spam complaints.

Brice's data suggests that logic is leaving substantial revenue on the table.

"You can email someone who cancelled much more than you think," he told me. "One of our brands sends three messages after someone churns over the next two months saying, come back, here's a one-click offer to return. And then after that, after they drop off that flow — this brand went further than even I recommended — they sent an email every single week to the entirety of their churned customer base. And the take rate on these were huge. Maybe 0.5%, which isn't huge in the grand scheme of things, but if you're sending that email every week and getting a very high take rate, you can see how that compounds."

Let's run the maths on that.

A subscription brand with 50,000 churned subscribers, sending one weekly reactivation email with a one-click reactivate CTA at a 0.5% take rate, reactivates 250 subscribers per week. Over a year, that's 13,000 reactivations from a base most brands have written off entirely. At even a modest subscription AOV and a 4–6 month average lifespan post-reactivation, the revenue impact is six to seven figures.

The reason this works is the same reason embedded action-led billing reminders work: when the friction is one click, the take rate compounds. A churned subscriber who would never log into a portal to reactivate will click a one-click button in an email if the offer is right.

I'd add an important caveat from the retention side: deliverability matters more on this segment than any other. Churned subscribers have lower engagement scores. Sending them weekly without proper segmentation and engagement-based suppression is a fast track to deliverability damage. The play works, but it has to be built carefully with proper exclusion logic, engagement scoring, and progressive suppression for non-responders.

The play: Extend your churned-subscriber sequence well beyond the standard 30–60 day window. Build a long-tail reactivation flow that sends one email per week to the churned base with a one-click reactivate offer. Vary the incentive monthly. Use engagement-based suppression to protect deliverability. Measure reactivation revenue against the cohort, not the open rate.

How this all connects to your broader retention strategy

The thread running through everything Brice and I discussed is the same thread that runs through every conversation I have with operators trying to scale LTV.

The brands compounding subscription LTV have stopped treating active subscribers as a fragile population to be left alone. Instead, they've recognised that:

1. Subscribers want flexibility, not silence. They will reward you for giving them choice and punish you for forcing rigidity. The brands that ask the right questions at the right moments retain longer.

2. The order-upcoming email is the most under-exploited window in subscription marketing. It is the single highest-intent touchpoint your subscriber will have with you all month. Wasting it on a generic billing notice is malpractice.

3. Friction is the silent killer of LTV. Every additional click between intent and action is a leak. The brands that have collapsed the action flow to one click — in-email swap, in-email upgrade, in-email reactivate — are the brands taking share.

4. Churn is not a single event. It's a cohort that keeps generating value if you stay in front of it. The reactivation tail is far longer than most brands respect.

What ties all of this back to broader retention strategy is the same point I made in the Retention Strategy Bible: LTV is a function of frequency × AOV × margin × lifespan. The plays Brice has described move three of those four variables simultaneously and most of them cost nothing in margin to execute. They're a redesign of the message, not a discount on the product.

That's the lever that compounds.

Frequently asked questions about emailing subscribers

Do billing reminder emails cause subscription churn?

Generic billing reminders ("your order ships Tuesday, you'll be charged $42") can cause a spike in churn. But Zaymo's holdout tests show that when the same email is reframed around flexibility with embedded options to swap, delay, accelerate, or upgrade — the cancellation rate is identical to sending no reminder at all, while total cohort LTV lifts by around 10%.

The conclusion: it's not the reminder that causes churn, it's the framing of the reminder.

When should subscription brands send order-upcoming emails?

Send them 3–7 days before the next billing date. The exact window depends on shipping cadence and product type, but the principle is the same: enough lead time for the subscriber to take a flexibility action (swap, delay, upgrade) before the order ships, but close enough to feel relevant. After order 3 in the subscription lifecycle, churn risk stabilises significantly, and order-upcoming emails become primarily an upsell opportunity rather than a churn risk.

What's the number one reason CPG subscribers cancel?

Having too much product. Across direct-to-consumer CPG subscription brands, the most common cause of cancellation isn't price, novelty fatigue, or product dissatisfaction — it's that the default cadence delivers product faster than the customer consumes it. Customers with a backlog of unused product hit the cancel button because cancelling is one click and changing the frequency is buried in a portal. Surfacing a one-click "delay my order" action in the billing reminder mitigates this directly.

How can I increase the take rate on subscription cross-sells?

Embed the action inside the email. Zaymo's data shows that interactive in-email CTAs drive 50% higher take rates than redirect links to subscription portals (like Recharge or Stay AI quick links) for the same offer at the same timing. Every click between the customer's intent and the completed action is a leak. The biggest single lift is collapsing the take-up journey to a single in-email click.

Should I email active subscribers about product launches?

Yes. The biggest myth in subscription marketing is that active subscribers should be excluded from broader marketing sends. The reality is that subscribers have a higher take rate on product launches than your prospect base, especially when the launch is paired with a subscriber-exclusive incentive (early access, bundle perk, 10–20% discount). Excluding them from launches doesn't protect their LTV — it caps it.

How often can I email churned subscribers?

Far more often than most brands assume. One of Zaymo's clients sends a reactivation email weekly to its entire churned subscriber base, with a one-click reactivate offer, and consistently sees a 0.5% take rate. At scale, that compounds into significant reactivated revenue annually. The caveat is that churned subscribers have lower engagement scores, so deliverability has to be protected with proper engagement-based suppression — but the contact frequency itself is not the problem most brands fear it is.

What's the difference between interactive email and standard email for subscriptions?

Standard email forces the subscriber to click through to a portal or website to manage their subscription, swap, upgrade, or reactivate it

Interactive email (AMP) lets the subscriber complete the action inside the inbox itself, with no redirect. Across Zaymo's data, the same offer in interactive format outperforms its redirect equivalent by 20–50% on take rate, and reduces attributed churn from notification messages by around 20% in the short term. The trade-off is that interactive email is only fully supported in some inboxes (primarily Gmail), so a graceful fallback is essential.

How do I measure whether my subscriber emails are driving churn or retention?

Run a holdout test. Hold out 50% of your subscriber base from a specific message type (e.g. the order-upcoming email) for a defined period, and measure both short-term cancellation rate and long-term LTV against the cohort that received the message. Most brands measure short-term cancellation only and stop there. The LTV picture often diverges over 60–90 days as the engaged cohort retains and spends more. Measure both windows before drawing conclusions.
