Why brands switch to Eternly
Your ecommerce and subscription data live in separate worlds. Your churn doesn't care.
Most Shopify brands are working from fragmented data. Shopify shows orders. Recharge shows subscriptions. Klaviyo shows opens. None of them talk to each other — which means you're making retention decisions based on incomplete information.
Eternly was built to close that gap. One platform that pulls everything together, surfaces what matters, and tells you what to do about it.
I can see the data. I just don't know what to do.
Eternly's AI advisor, Longevity Leon, turns your retention metrics into specific, prioritised actions — grounded in your actual customer data and brand context.
My subscription tool and my Shopify don't talk to each other.
Eternly unifies data from Recharge, Loop, and Skio with your Shopify store — giving you one cohesive view of every customer across every touchpoint.
We try tactics but we can't tell if they're working.
The Changelog lets you log every campaign, flow change, and pricing test. Eternly then shows you how your retention curves shifted before and after each intervention.
Meet your retention advisor
Introducing Longevity Leon.
Leon is Eternly's built-in AI advisor, trained on retention strategy and grounded in your actual store data. He doesn't surface generic insights — he analyses your specific cohorts, cancel reasons, and CLV trends, then tells you exactly what to do.
Before Leon makes any recommendation, he reads your Changelog — every campaign, every flow change, every tool you've tried. That means no duplicate suggestions and no wasted effort.

- →Subscription-aware (understands pause vs cancel vs churn)
- →Tells you the why, not just the what
- →Gets smarter the longer you use it

The feature no one else has built
The Changelog.
Finally know if what you're doing is working.
Most brands run experiments without ever knowing if they moved the needle. Did the win-back flow help? Did the pricing change hurt M+3 retention? The Changelog gives you a record — and Eternly shows you the data around every entry.
Every time Leon generates a recommendation, he checks the Changelog first. No repeating tactics that didn't work. No suggesting flows you already have.
