Fullenrich

FullEnrich is a B2B contact enrichment platform that uses a waterfall methodology to find email addresses and phone numbers by querying more than 20 data providers in sequence.

If you are searching for Full Enrich Chrome extension, I want to let you know that Full Enrich Chrome extension no longer exist. It has been shut down 2 years ago. Even though the Chrome extension does not exist, you can continue to use the Full Enrich API key, which exists.

If you will visit the Full Enrich website and purchase any of the plan, you will be able to create your API key and use it. The API key is available to integration like Zapier, Make, n8n, or Clay. Most experts use Full Enrich via Clay.

The platform aggregates results from multiple premium vendors, applies triple email verification to keep bounce rates under 1%, and delivers both mobile and landline numbers with regional optimization for US, EMEA, LATAM, and APAC markets.

It is best suited for sales teams, SDRs, and growth-focused B2B companies that need maximum contact coverage without managing separate subscriptions to multiple data vendors, with a free tier available and paid plans starting at $29.

Popular tools similar to Full Enrich are Prospeo, Findymail and ContactOut

How FullEnrich Waterfall Enrichment Works

Waterfall enrichment is a sequential lookup process where a platform queries one data provider, and if no result is found, automatically moves to the next provider in the chain.

FullEnrich applies this logic across more than 20 vendors, stopping as soon as a verified result is returned.

This approach consistently outperforms single-source tools because different databases have stronger coverage in different geographies and industries.

A provider that excels at US tech contacts may have thin coverage in EMEA manufacturing, so the waterfall fills those gaps automatically.

The platform also selects which vendors to query based on the geographic location of the lead, meaning a contact in Germany will be routed through EMEA-optimized sources first.

Reported find rates are 89% for email and 86% for phone in the US and Canada, dropping to 84% email and 71% phone in EMEA, and 78% email and 66-67% phone in LATAM and APAC.

Email Verification and Data Quality

Finding a contact is only half the problem. Sending to unverified addresses damages sender reputation and reduces deliverability across an entire domain.

FullEnrich addresses this by running discovered emails through three separate verification tools rather than one, which reduces the chance of a false positive passing through.

The platform also handles catch-all domains, which are addresses that accept all incoming mail regardless of whether the specific mailbox exists.

These are normally considered risky to send to, but FullEnrich claims to verify up to 80% of catch-all addresses as safe, expanding the pool of reachable contacts.

On the phone side, the platform prioritizes mobile numbers over landlines and only charges credits for mobile results. Landlines that are found are returned free of charge.

For US and Canada contacts, an additional validation layer cross-references phone line ownership against the lead's name to reduce wrong-number calls.

Integrations and API

FullEnrich connects with more than 1,000 applications through its integration layer, covering CRMs, spreadsheet tools, and outbound automation platforms.

Teams that want to embed enrichment directly into a product or internal workflow can use the FullEnrich API to trigger lookups programmatically without manual CSV uploads.

This makes it practical for RevOps teams building automated lead routing or enrichment pipelines that run without human intervention.

Security and Compliance

FullEnrich holds SOC 2 Type II certification, which means an independent auditor has validated its security controls and data handling practices.

The platform is also aligned with GDPR for European data subjects and CCPA for California residents. Organizations with procurement or legal review requirements can request the SOC 2 report directly through the trust portal.

Who Uses FullEnrich

The platform is primarily used by B2B sales teams and SDR functions that have already identified their ideal customer profile but are losing pipeline because they cannot reach a large portion of those contacts.

It is also used by growth and demand generation teams that run outbound campaigns at scale and need high match rates to justify the time invested in list building.

Companies that have previously used tools like ZoomInfo, Cognism, or Lusha and found coverage gaps in specific regions or verticals are a common fit, as the waterfall approach directly addresses the single-vendor coverage problem.
