The free audit · Expert-led
A free Klaviyo retention audit that ends with a gameplan you keep.
Most agencies sign you, then disappear for weeks to "audit" before telling you anything. We do the opposite. Before you pay a cent, our retention specialists tear down your Klaviyo and lifecycle setup by hand and hand you the plan.

- 02

Pop-ups and sign-up offers, the welcome series, browse, cart and checkout recovery, and nurture for subscribers who haven't bought yet.

Who it's for
- Shopify or D2C brands with consistent monthly sales
- Products customers can buy again: consumables, beauty, wellness, food, pet, apparel, home
- On Klaviyo (or ready to move to it)
- Want a Klaviyo-first team to own retention and LTV end to end
Probably not a fit
- Pre-launch stores or brands still finding product-market fit
- One-time purchases with no reason to reorder
- Looking only for one-off email designs or ads management
- Looking for guaranteed numbers before we've seen your data
Why now: every month, Klaviyo flows go stale, segments stay one-size-fits-all, and subscription saves stay unbuilt, and all three get harder to fix later.
