Background
This company produces gluten-free snack bars and is co-founded by 2 brothers.
When Elliott reached out to me in late June 2024, they were running MailChimp. They had fine for basic sends, but not built for the revenue-driven automation a growing brand actually needs.
And one thing that made this project stand out was that the I found one of their products on a grocery store shelf before the engagement even started, bought it, and tried it. Loved it.
When the product genuinely works, email marketing becomes a lot easier to write.
Klaviyo Flow Performance
These are the actual Klaviyo stats from the flows after migration (with full permission of course — had to cut out and blur the screenshots this way cos of NDA and stuff). The abandoned cart numbers alone show exactly how much the client was leaving on the table with MailChimp: a 43% open rate and 14% CTR is well above industry average for any ecommerce flow.

What Made It Work
- The Right Platform: Klaviyo gave the segmentation, automation, and analytics the muscle that MailChimp simply doesn’t have at this level for ecommerce. The migration itself opened up capabilities that weren’t possible before.
- A Strategic Plan: Every step was mapped before execution started. No guesswork, or switching lanes mid-project… We followed a our structured approach and system through to completion.
- 2-Way Accountability: We didn’t just build the strategy and hand it over. We held them accountable to following it too. And I don’t have to tell you that shared ownership is what gets results across the finish line.
The Takeaway:
Revenue was up 12% within the first 30 days. For a CPG brand selling through grocery and online, that kind of email-driven lift in a single month shows exactly what switching to the right platform and running it properly can do.
