Apollo vs Clay vs ZoomInfo, tested
We ran 50,000 leads from each through verification. Here's what we found.
Apollo
Wide coverage, ~25% catch-all, ~6% hard bounce raw.
Clay
Best when waterfalled with multiple providers. Verify after.
ZoomInfo
Highest stated accuracy, but expensive and US-heavy.
Verdict
Doesn't matter — verify before sending, regardless of source.
