CUSTOMERS

Loved by teams at every scale

"

ClearCorex paid for itself in the first week. Our deliverability went from 71% to 96%, and the team stopped manually scrubbing lists in spreadsheets. It's now a critical part of our growth stack.

β˜…β˜…β˜…β˜…β˜…

We process 40M emails a quarter through ClearCorex. The Rust engine is unreal β€” it's the fastest tool in our entire stack.

Switched from three other tools to one. Cleaner data, fewer integrations to maintain, half the cost. Easy decision.
