FullEnrich
FullEnrich runs contact enrichment queries across multiple data providers in sequence, improving email and phone match rates compared to relying on a single source.
Best for: RevOps teams and growth marketers who need high match-rate contact data but want to avoid paying for a full Clay subscription or managing multiple data provider contracts separately.
FullEnrich is a waterfall enrichment tool, a category that has emerged clearly only in the last two years. The idea is straightforward: instead of querying one data provider and accepting whatever match rate that vendor offers, the tool fires the same lookup sequentially (or in parallel) across multiple providers, Apollo, Hunter, Dropcontact, and others, and returns the first verified result. This materially improves match rates for email and mobile phone data, particularly for European contacts where US-centric databases have historically poor coverage. FullEnrich packages this logic into a relatively simple interface with CSV upload, API access, and CRM integrations.
The most common comparison a buyer will run is FullEnrich versus Clay. Clay is a broader data orchestration and workflow platform that also supports waterfall enrichment but requires more setup and carries a higher price point, making it better suited to teams who want to build complex enrichment and personalization workflows. FullEnrich is narrower in scope and positioned for teams that specifically want better contact data match rates without the learning curve. Other comparisons include Findymail (email-focused waterfall), Prospeo, and Enrow. The deciding factors are usually the provider mix in the waterfall, credit pricing, and CRM or sequencer native integrations.

Frequently asked questions
What is waterfall enrichment and why does it matter?
Waterfall enrichment means querying multiple data sources in sequence until a verified result is found, which consistently produces higher match rates than any single provider can deliver on its own.
How does FullEnrich compare to Clay?
Clay is a full data orchestration platform where waterfall enrichment is one feature among many, while FullEnrich focuses specifically on contact enrichment match rates with a simpler setup. Teams wanting just better email and phone data will find FullEnrich faster to implement; teams wanting to build conditional workflows, AI personalization, or complex multi-step automations will likely outgrow it.
Does FullEnrich work for non-US contact lists?
Yes, and European coverage is one of the explicit selling points, since the waterfall includes providers with stronger EMEA data than purely US-centric databases like Apollo.
