How the Works
We query providers in priority order. The moment we find accurate data, we stop, saving you credits and ensuring the highest quality.
Credit Efficiency
1
credit per verified email
Only pay for one successful match. If the first provider has the data, we stop there. No wasted queries to downstream providers.
Speed Priority
Real time
single-record lookups
Providers are ordered by response time, so the fastest reliable source answers first and the cascade stops as soon as it has a verified match.
Accuracy First
98%
verified emails
We prioritize providers with the highest accuracy rates, ensuring your Golden Record is always reliable.
