What Is FullEnrich and What Does It Do?

FullEnrich is a B2B contact data enrichment platform that finds email addresses and mobile phone numbers for sales prospects. It works by running each contact through a "waterfall" of 20+ premium data vendors in sequence, so if one provider can't find a match, the next one tries — the company claims an 80%+ find rate. It's built for sales, marketing, and go-to-market teams that need contact data for prospecting, inbound lead enrichment, or CRM records.

How the waterfall enrichment model works

Most data tools rely on a single vendor, which caps your coverage at whatever that vendor happens to have. FullEnrich aggregates 20+ sources — the site names Clearbit, Wiza, ContactOut, Anymail Finder, Snov, and Hunter among them — and queries them in order until it finds a valid result.

The practical effect: you get the combined coverage of many providers through one account, one interface, and one subscription. FullEnrich frames the value as "20+ data sources for the price of 1."

It also adjusts which vendors it queries based on the lead's location, aiming for the best find rate per region. The site lists these regional find rates:

What it actually finds

• Email addresses — work emails, verified before delivery
• Mobile phone numbers — the site states you only pay for mobile numbers, not landlines

Accuracy and verification

Coverage is only useful if the data is correct, so FullEnrich layers verification on top of the waterfall:

• Triple email verification — three independent engines must agree on an email. If one disagrees, the email is discarded.
• Catch-all resolution — instead of flagging catch-all domains as "risky" and stopping, it attempts to resolve the specific mailbox.
• Bounce probability — every delivered email carries its own predicted bounce rate, so you can estimate your bounce exposure before sending.
• Paid-data filtering — the site claims 31.53% of the data it buys fails its verification and never reaches you or your invoice.

Ways to use it

FullEnrich is designed to fit into existing workflows rather than add a new tool to learn. Supported entry points include:

• Prospect search — find new contacts and accounts matching your ICP
• Inbound email enrichment — enrich leads as they come in
• Manual enrichment — add names and companies one at a time
• CSV/Excel upload — enrich a list in bulk
• CRM sync — pull a list from HubSpot
• API, MCP, and no-code integrations — connect to CRMs, AI agents, and other tools

Who it's for

FullEnrich targets B2B sales and go-to-market teams that:

• Need contact data at a scale or coverage level a single vendor can't deliver
• Prospect internationally and want region-optimized vendor selection
• Care about bounce rates and deliverability, not just raw match counts
• Want enrichment embedded in their CRM or existing tools

Getting started and pricing

You can try it with 50 leads free, no credit card required. The platform states it is GDPR and CCPA compliant. For current plan details and per-credit costs, check the pricing page directly, since rates depend on volume and usage.

If your main bottleneck is missing contact data — especially for hard-to-find prospects or non-US markets — FullEnrich's multi-vendor waterfall is the core reason to consider it over a single-source tool.
