Skinny Fizz is a fast-growing New Zealand beverage brand with a healthy, engaged subscriber list and almost nothing in Klaviyo actually working for them. Email went out occasionally, with no automated flows behind it, which meant every dollar of email revenue had to be earned from scratch each send. Worse, the subscribers most likely to buy, the ones who'd just browsed a product or abandoned a cart, were never being messaged at the moment they were closest to converting.
The challenge
A list this engaged should have been doing far more work. Instead, revenue depended entirely on manual campaign sends, with no automated safety net capturing browse and cart abandonment, and no post-purchase sequence turning first-time buyers into repeat customers.
What In-box did
- Rebuilt the Klaviyo account structure, lists and segments from the ground up
- Launched the four core revenue flows: welcome, abandoned cart, browse abandonment and post-purchase
- Set a consistent campaign rhythm built around the product range itself, not around constant discounting
- Cleaned up deliverability and list health so campaigns actually reached the inbox instead of getting filtered
The results
Within 30 days, email revenue was up 921%. Automations, not one-off campaigns, carried a meaningful share of that revenue from month one, meaning the growth wasn't a single spike but a structural shift in how the channel performed. Campaign engagement held steady even as send volume increased, which matters: it's easy to grow revenue short-term by mailing harder and burning the list; Skinny Fizz's numbers moved without that trade-off.
"Gavin and the team have turned our email CRM into a profitable growth engine and a source of new prospective customers. Creatively spot on, efficient and really easy to deal with. We highly recommend In-box."
The takeaway for other beverage and DTC brands: if your list is healthy but your automations are thin, the fastest revenue you'll ever unlock is usually sitting in the flows you haven't built yet, not in the next campaign.
