How Big Berkey water filters generated over 20× ROI with the help of Opensend & One10Media
With One10Media and Opensend, Big Berkey captured over 52K new subscribers, drove $250K in revenue, and recovered another $100K through Reconnect, all in their first year.
The challenge
Every day, thousands of high-intent visitors landed on Big Berkey's site, but many left without a trace: no email, no checkout, no retargeting opportunity.
Their growth was limited by the same wall many DTC brands hit: lack of identifiable contacts to market to.
The strategy
Instead of reinventing the wheel, the team focused on scaling what already worked, only faster:
Opensend was configured to capture engaged visitors, not casual browsers.
One10Media provided strategy and implementation to ensure Opensend was deployed for maximum ROI, not just installed and left to run.
A custom welcome flow introduced Opensend-identified users and funneled them into the existing customer journey.
Opensend contacts were fed into abandoned checkout flows and campaigns for additional monetization.
How Opensend helped
Opensend's identity resolution captured intent in real time, feeding contacts into Klaviyo where One10Media managed messaging and flows. Reconnect extended this impact further by tracking returning customers across devices and sessions, adding incremental revenue without extra ad spend.

Why this worked
Big Berkey Water Filters didn't need a multi-channel overhaul. With Opensend providing the identification technology and One10Media pairing it with the right strategy, timing, and flows, the brand turned previously unreachable traffic into revenue at scale.
No massive changes, just smart amplification.
"I love that our client list growth has increased more than 6% year-over-year since starting with Opensend. It's rare to see a tool deliver results this consistently."
