When Revnox looks for a contact's details it does not rely on one provider. It runs a waterfall: providers in turn, merging what each returns, and stopping early once the key fields are filled.
By default the order is Apollo, then Hunter. A workspace can set its own order or switch a provider off, and a provider whose key was refused at its last check is skipped rather than called.
A contact database with strong coverage of US tech companies and startups.
Indexes email patterns from public sources, and suits companies with a clear, consistent email format (e.g., firstname@company.com).
When verification is switched on for the workspace, each address found is checked with an email verification service: MillionVerifier first, then Hunter's verifier. The result is recorded as valid, invalid, catch-all or unknown. Only an address marked invalid is refused when a campaign sends; catch-all and unknown addresses are sent.
The Enrichment page in the sidebar lists each provider and when its key was last checked. Admins and owners can add the workspace's own key there; without one, a provider uses the key configured for the whole Revnox instance, if there is one.
Every provider call is recorded with what it cost. A lookup the provider performed is charged at its price, including one that found nobody, because providers bill for those. A request the provider refused is recorded as free, and one whose outcome never came back is recorded with no figure rather than a guess.
