What is FullEnrich?

FullEnrich is a B2B contact-data enrichment platform built around waterfall enrichment. Instead of relying on one data provider, it queries more than 15 premium vendors one after another for every contact, returning the first high-confidence match. That cascade matters: where a single tool like Apollo or Hunter might match 50–60% of a list, a well-built waterfall routinely pushes that to 75–90% on US and EU business contacts. FullEnrich finds verified work emails, mobile and cell phone numbers, and personal emails, and layers on reverse email lookup, advanced email and phone verification, and live company and person enrichment across dozens of data points.

It is designed for sales development, RevOps, agency, and growth teams who live and die by deliverable contact data. You can paste a single lead, upload a CSV, build a prospect list from scratch with its people-and-company search, or run enrichment automatically through the API. A defining detail of the pricing model is that FullEnrich only charges a credit when it actually finds and verifies a contact — failed lookups do not burn credits — which makes cost-per-contact far more predictable than tools that charge per attempt. The company is GDPR and CCPA compliant, and every plan includes unlimited users with a shared team credit pool.

How waterfall enrichment works

Waterfall enrichment is the core idea, so it is worth understanding exactly how FullEnrich runs it. For each contact you submit, the platform sends the lookup through a sequenced chain of 15+ data providers — the kind of vendors you would otherwise buy and stitch together yourself, such as Apollo, Dropcontact, Hunter, RocketReach, ContactOut, Wiza, Snov, Findymail, and others. The waterfall is not random: FullEnrich uses the lead's location to dynamically prioritize which provider it tries first, because each vendor has regions where its coverage is strongest. The system keeps querying sources one by one until it gets a match, then stops — so you pay for one credit, not for every vendor it touched.

The headline numbers from FullEnrich are roughly an 80%+ overall success rate, near-100% work-email coverage, around 80% mobile-number coverage, and a ~1% bounce rate thanks to the triple verification. In our read of independent reviews, those figures hold up best for US and EU/UK business contacts (roughly 70–85% email match), while APAC and LATAM coverage is noticeably thinner — a fair trade-off to flag before you commit a large international list.

Key features

FullEnrich integrations

FullEnrich is built to drop enriched data straight into the tools your team already runs, rather than living as another silo. On the CRM side it connects to HubSpot, Salesforce, and Pipedrive so enriched contacts and firmographics sync into your pipeline. For automation, it supports Make and Zapier, which opens up routing enrichment results into thousands of downstream apps and sequencers without code. Developers get a full REST API (available on every tier, not gated behind enterprise) plus no-code building blocks for custom workflows.

The MCP Server is the most forward-looking piece here: by exposing enrichment over the Model Context Protocol, FullEnrich lets agents in Claude, OpenAI/Codex, and Perplexity look up and verify contacts on demand — a genuinely useful edge if your team is building AI-driven prospecting workflows in 2026.

FullEnrich pricing explained

FullEnrich is credit-based: one verified contact found costs roughly one credit, and lookups that fail do not cost anything. Everything starts with a free trial of 50 credits and no credit card. Paid plans scale by the volume of credits you need, with tiers that step up from 500 credits all the way to 100,000. The entry annual plan lands around $26/mo billed yearly for 6,000 credits — a meaningful discount over paying monthly — while higher Pro tiers add more credits (1,000, 1,500, 2,000, 5,000, 10,000 and up), and Scaleups & Agencies pricing is custom for large volumes. Unlimited users are included on every plan, since you pay for data, not seats. Credits roll over — 3 months on monthly plans and 12 months on annual — so a slow month is not wasted. Exact prices move with packaging, so confirm the current numbers at signup; the free 50 credits let you validate match rate on your own list before committing.

FullEnrich vs Clay vs Apollo.io

The short version: FullEnrich wins on enrichment accuracy-per-dollar and simplicity, Clay wins on depth and customization if you have the time to build, and Apollo wins if you want database, enrichment, and outreach bundled in one seat. Many teams actually run FullEnrich inside Clay or alongside Apollo as the high-hit-rate enrichment layer.

Is FullEnrich worth it?

For a team whose pipeline depends on reaching real people, yes. FullEnrich is one of the cleanest implementations of waterfall enrichment available: it stacks the vendors you would otherwise license and reconcile by hand, only charges when it succeeds, triple-verifies emails to keep bounces near 1%, and never nickel-and-dimes you on seats. The honest caveats are that it is enrichment-only (no outreach or intent signals) and that match rates fall outside the US/EU/UK, so an APAC-heavy list will under-perform. But the entry barrier is essentially zero — 50 free credits with no card means you can measure the exact lift on your own data before deciding. If contact accuracy is the bottleneck in your outbound, FullEnrich is an easy Buy.
