Clay is the default pick when single-provider find rates leave too many gaps: waterfall logic across 150+ providers pushes email coverage to 80-90% on most ICPs.

Use-Case Routing
Clay vs Apollo vs Lusha: which fits your enrichment motion
The right pick depends on where enrichment breaks down in your current workflow. Outbound list coverage, CRM freshness, and routing intelligence are three distinct problems with different tool requirements.
Any single B2B data provider leaves 35-50% of records unenriched on a typical outbound list. Waterfall tools like Clay push coverage to 75-90% by applying a second source when the first returns empty.
Common Questions
4 data enrichment questions, answered
Waterfall enrichment tries multiple providers in sequence: if provider A returns empty, provider B fills the gap, then provider C if B also fails. Single-provider tools stop after one attempt, leaving 35-50% of records empty. It matters most for non-US markets, niche verticals, or SMB contacts where any single database has weak coverage.
If Apollo's find rate covers 70%+ of your target list, Clay's waterfall credit overhead is hard to justify. If find rates are below 60% and empty records mean sequences don't get sent, Clay's coverage improvement typically pays for itself within weeks of active campaign volume.
A B2B database discovers new contacts by ICP filters. An enrichment tool takes records you already have and adds missing fields: verified email, phone, job title, seniority, and company size. Most tools on this list do both.
ZoomInfo covers most enrichment needs at enterprise scale. Teams add Clay specifically to fill coverage gaps on SMB contacts, non-US companies, or fast-growing startups ZoomInfo indexes less deeply.
