Exclusive Case Study

how we brought cancelled subscribers back to a supplement subscription brand, and cut how many cancel

Ritual Labs makes Happy Liver, a daily liver support supplement made with milk thistle, NAC and choline. Most customers buy it on subscription and take 2 capsules a day.

When we started in 2026, the store was winning new subscribers fast. Keeping them was the harder part. Ritual Labs needed fewer people to cancel, and a way to bring back the ones who already had.

when the product works over months, the real growth is in the subscribers who stay

A daily supplement is an easy habit to drop. At Ritual Labs, the biggest drop-off comes right after a subscriber's second order.

So we wrote for the whole subscription, cancels included. The emails set honest expectations for the first months. When someone does cancel, we ask them back with an offer they can take in 1 click. And we keep looking for the exact point where people leave, so we can fix it.

emails that help a daily habit last.

Most of Ritual Labs' campaigns teach before they sell. They explain what is in each capsule and how long the routine takes, so the doubt a subscriber feels in month 1 doesn't turn into a cancel.

"Wait… it takes 3 months?" said it plainly. New customers now also get a post-purchase email on what to expect after their order.

cancelled subscribers came back at 9 times the normal rate.

Over the late summer and autumn we sent 7 win-back emails to subscribers who had cancelled. We set up Ritual Labs' Loop subscriptions and Klaviyo to work together, so each email carried a button that restarts the subscription in 1 click.

In the days around each send, cancelled subscribers restarted at about 9 times the rate of a normal day. Earlier in the summer, a small account credit brought back nobody. A bigger discount on the first box back, with the 1-click button, is what worked.

Ritual Labs cancels per 100 renewal orders, down 27% in the 3 months after the subscriber emails went live

cancels fell from 64 to 47 per 100 renewal orders.

Before our subscriber emails went live, Ritual Labs had 64 cancels for every 100 renewal orders. These are the emails for subscribers who pause, cancel or have a payment fail. Three months later the figure was 47. Part of that fall is the subscriber base maturing, but the drop began when the new emails went live.

We also found where most people leave. Over the summer, more than half of the subscribers who paid for a second order cancelled before a third. We are now testing a free gift at exactly that point.

Some questions we get often.

What does Email Kong actually do?

We help eCommerce brands grow repeat revenue. That means building out your full retention strategy - email, SMS, WhatsApp, and more - so you can convert more customers, increase LTV, and reduce reliance on paid ads.

Are you just an email agency?

Not even close. We’re a full CRM and retention partner. Email is the foundation, but we also optimize your tech stack, fix broken data flows, scale SMS, improve tracking, and design customer journeys across every touchpoint.

What makes Email Kong different from other email agencies?

We don’t do templates or “30% email revenue” vanity metrics. Every strategy is built from scratch based on your business model, goals, margins, and customer behavior. And everything is done in-house - no juniors, no outsourcing.

Who will I actually work with?

You work directly with senior strategists who have built and scaled brands - not junior account managers. From strategy to execution, we stay hands-on.

Do you only work with Klaviyo?

We're a Klaviyo-certified email marketing agency - we build everything natively in the platform, though we're no strangers to the wider CRM ecosystem when the brief calls for it.

How do I know if I’m a good fit?

If you’re a DTC brand doing over $2M/year and care about retention, LTV, and owned growth - you’re in the right place. Especially if you’re tired of generic playbooks and want a partner who actually gets under the hood.

Can you just audit what I have first?

Absolutely! Our free audit reveals exactly where your setup has gaps, and what we’d do to fix it. There’s no pressure to work together right away. You’re welcome to take the insights and run with them. When you're ready to work together, we’ll be here.
