Harry's reduces subscriber cancellations by 17% with Zaymo

Harry’s has built one of the most recognized subscription businesses in men’s grooming, delivering razors and blade refills on a recurring cadence. Their email program runs through Klaviyo, with billing reminder flows as a cornerstone of the subscriber lifecycle.

Initial Problem

The most common cancellation reason at Harry’s was straightforward: subscribers were overstocked. Blade refills were arriving on a fixed cadence, but usage varied — and for many subscribers, inventory was accumulating faster than they could work through it.

Two friction points were quietly converting a timing problem into permanent churn:

1. Subscribers who wanted to push back their next shipment had to leave the email, log in to the site, and navigate their account settings. Most didn’t bother. Cancelling was simply easier — a permanent solution to what was really a temporary problem.
2. The billing reminder email — the highest-attention touchpoint in the subscription lifecycle — had no self-serve release valve. It created urgency with no easy outlet, making it a reliable churn trigger rather than the retention moment it should have been.

The support team absorbed the downstream cost: inbound contacts from subscribers asking to adjust or delay deliveries were a persistent volume driver.

Zaymo’s Solution

Harry’s embedded Zaymo’s interactive subscription portal directly into its billing reminder email in Klaviyo, giving subscribers everything they needed to manage their delivery without ever leaving their inbox.

1. One-tap delay, skip, and frequency controls — inside the email. Subscribers could push back their next shipment, skip a delivery, or adjust their cadence with a single tap — no login, no site navigation.
2. A fully customizable widget that matched the Harry’s brand. The Zaymo widget was configured to look and feel native to Harry’s email templates — custom CTAs, fonts, and layout. The team found the depth of customization to be one of the standout aspects of the platform.
3. An unexpected win: reactivations from the post-cancellation email. Beyond the billing reminder, Harry’s added a Zaymo reactivation widget to the post-cancellation confirmation email. Subscribers who had been cancelled due to payment failures were reactivating directly from that email with no offer or incentive — just a one-click reactivate CTA.

Setup

To isolate the effect of in-email interactivity, Harry’s ran a controlled A/B test on the billing reminder flow. The control group received the standard billing reminder with a link to the subscription portal on the site. The Zaymo-powered variant embedded the full account portal directly inside the email.

Both variants were sent to statistically significant subscriber segments. The 17% reduction in cancellations is attributable entirely to the presence of the in-email portal — not to any change in offer, copy, or send cadence.

Results

Beyond the billing reminder, Harry’s also saw subscribers reactivating directly from the post-cancellation confirmation email — with no discount or incentive, just a one-click reactivate option powered by Zaymo.

Takeaways

Harry’s success came down to recognizing that overstocked subscribers weren’t trying to leave — they were trying to catch up. The billing reminder was already the moment of highest attention in the subscription lifecycle. By giving subscribers a frictionless way to delay or skip directly inside that email, Zaymo turned a historically reliable churn trigger into a retention moment.

The unexpected upside — reactivations from the post-cancellation email, with no offer attached — illustrates a broader principle: a meaningful share of subscription cancellations aren’t intentional. They’re the result of friction, expired cards, and the absence of an easy alternative. Remove that friction at every touchpoint, and subscribers who would have been lost instead recover themselves.
