FullEnrich Review 2026: Multi-Waterfall Contact Enrichment — Pricing and Hit Rate

FullEnrich is a credit-based B2B contact enrichment platform that cascades through 25+ sources to maximize email and mobile hit rates. Starting at $55/mo with no seat fees, it achieves 70–85% hit rates on US enterprise contacts and 50–60% on APAC/LATAM markets. It is the deepest pure-waterfall enrichment tool in its price tier. Our rating: 4.3/5.

The case for FullEnrich is straightforward: most enrichment tools query one database and stop. If that database does not have your prospect, you get nothing. FullEnrich solves this by running a cascade — if Provider A fails, Provider B runs, then C, then D — until a verified result is found or the waterfall is exhausted. Failed lookups do not consume credits.

The limitation is equally clear: FullEnrich enriches contact data. It does not send outreach, and it does not tell you when a company is ready to buy, so it is one piece of a larger stack rather than the whole answer.

This review covers the waterfall hit rate in practice, the credit pricing math at each plan tier, data coverage by region, how it connects to your stack, and a direct comparison with Clay and Apollo for teams evaluating their enrichment options in 2026.

What Is FullEnrich?

FullEnrich is a B2B contact enrichment platform founded in France and built around a single architectural bet: multi-waterfall enrichment beats single-source databases on hit rate, every time. Instead of maintaining a proprietary contact database, FullEnrich acts as an orchestration layer — routing your input records through 25+ external sources in a defined cascade and returning the first verified result found.

The target user is a contact data ops professional, RevOps engineer, or GTM team that needs to enrich large prospect lists at predictable cost without managing provider relationships individually. FullEnrich handles the cascade logic, provider prioritization, and deduplication — you send a name and company domain, you get back an email or mobile number.

The founders chose a credit-only monetization model with no seat fees, which makes it fundamentally different from per-user tools like Lusha or Kaspr. A team of 10 SDRs using FullEnrich pays the same monthly rate as a team of 1 — the cost scales with usage, not headcount. This is a significant structural advantage for mid-sized outbound teams running high-volume enrichment.

FullEnrich Pricing: Credits, Plans, and What You Actually Pay

FullEnrich publishes its pricing — a rare practice in B2B data tools — and uses a credit model where you only pay when verified data is found. Records where the waterfall exhausts every source without a result cost nothing. As of September 2026, the lineup is simple: a free trial, one self-serve Pro plan, and custom Enterprise pricing.

Credit cost by data type

Not every lookup costs the same. Work emails and reverse email lookups cost 1 credit each, personal emails cost 3 credits, and mobile numbers cost 10 credits. B2B profile and company data is included free with contact enrichment, or 0.25 credit when you request it on its own.

The real cost math

Because failed lookups are free, your cost per verified work email is simply the credit price: about $0.055 at the entry Pro rate of $55 for 1,000 credits. Mobile numbers are where budgets move. At 10 credits each, the same 1,000 credits cover only 100 mobile numbers, or roughly $0.55 per number found. Enriching 500 contacts with both a work email and a mobile number can take up to 5,500 credits if every lookup succeeds, so phone-heavy teams should budget well beyond the entry Pro allocation.

Unused credits roll over for three months on monthly billing and twelve months on annual billing, which softens the cost of uneven months. The free trial's 50 credits cover about 50 work emails or 5 mobile numbers, enough to sanity-check hit rates on a sample that mirrors your real ICP before committing.

FullEnrich Hit Rate: What the Waterfall Actually Delivers

Hit rate is the core metric for any enrichment tool — the percentage of input records that return a valid email or phone number. Single- source tools (Apollo, ZoomInfo own database) typically achieve 55–70% on well-defined US enterprise ICP lists. The multi-waterfall architecture is specifically designed to push this ceiling higher.

FullEnrich's reported hit rates by region, based on user data and independent benchmarks:

Why waterfall beats single-source

The practical improvement from a multi-provider waterfall over a single-source tool on a 1,000-record US enterprise list is meaningful. Apollo's own database typically returns 580–650 matches on the same list. FullEnrich's cascade returns 700–800. That is 50–150 additional contacts per 1,000 records — a 10–15% improvement that compounds significantly at scale.

The waterfall advantage narrows in high-LinkedIn-density markets (US tech enterprise) where most providers draw from the same upstream sources. The advantage is most pronounced for roles with low social media presence — finance, legal, operations — where specialized providers in the cascade have data that LinkedIn-scraping tools simply do not.

FullEnrich Data Coverage: Email, Mobile, and Firmographics

Email coverage

Email enrichment is where FullEnrich is strongest. US enterprise and EU/UK enterprise coverage is deep because multiple providers in the cascade have independently indexed these markets. For the Fortune 1000 and equivalent EU enterprise, expect 80%+ hit rates. Coverage thins on SMBs — companies under 20 employees — because smaller organizations have less digital footprint for providers to index. APAC and LATAM email coverage is the weakest link in the waterfall, reflecting the overall sparseness of English-language professional data in those markets.

Mobile number coverage

FullEnrich sources mobile numbers through partner providers that provide Diamond-tier equivalent data — meaning verified, not just scraped. Mobile hit rates are consistently lower than email across all regions because fewer providers in the cascade have verified phone data. US enterprise mobile coverage at 45–60% is competitive with single-source tools but below Cognism Diamond Data for UK and EMEA senior executives, which is the gold standard for verified phone enrichment.

For teams where phone coverage is the primary requirement, Cognism remains the stronger option for UK/EMEA cold calling. For teams where email is primary and mobile is supplementary, FullEnrich delivers acceptable mobile coverage without paying Cognism's $15,000+ annual minimum.

Company and profile data

As of September 2026, FullEnrich returns B2B profile and company data alongside contact enrichment at no extra credit cost, or for 0.25 credit when you request it on its own. It is a supporting layer rather than the core product: the waterfall is built to find emails and mobile numbers, so teams that need deep firmographic or technographic research may still pair FullEnrich with a dedicated company data source or with Clay.

FullEnrich Integrations: How It Fits Your Stack

FullEnrich connects to the most common GTM stack components through a combination of native connectors, Zapier, and its REST API. The integration surface is intentionally minimal — FullEnrich is not trying to be a platform, just a high-quality enrichment layer that pipes into whatever tools you already use.

The missing integrations tell the product story clearly: no native Salesforce connector and no direct Outreach or Salesloft push. HubSpot is the one CRM with a native sync; everything else runs through Zapier, Make, n8n, or the API. FullEnrich is a data service, not a platform, so Salesforce teams should plan for that integration work up front.

FullEnrich Pros: What It Does Well

• ✓
  Deepest waterfall in the price category. 25+ sources cascaded automatically deliver 10–15% higher hit rates on US enterprise lists than single-source tools. Few tools at a $55/mo entry price match this waterfall depth.
• ✓
  Transparent credit pricing. Published rates, no seat fees, failed lookups don't consume credits. You can calculate exact cost before committing. Rare in a category where most vendors hide pricing behind sales calls.
• ✓
  No seat fees. Cost scales with usage, not headcount. A 10-person team pays the same as a 1-person team on the same credit allocation. This makes FullEnrich significantly cheaper than per-user tools (Lusha, Kaspr) for mid-sized outbound teams.
• ✓
  API included on all plans. Bulk enrichment, CSV upload, and REST API access come with every tier — not locked to enterprise. This makes FullEnrich practical for technical teams and RevOps engineers who want programmatic access without a premium plan.
• ✓
  Free trial and credit rollover. 50 free credits with no credit card let you test hit rates on your own list, and unused credits roll over for three months on monthly billing or twelve on annual billing, so slow months do not waste budget.
• ✓
  Clean product with a clear use case. FullEnrich does one thing and does it well. No feature bloat, no upsell to signals you don't need, no platform lock-in. If you need high-volume enrichment at predictable cost, the product is exactly what it says on the label.

FullEnrich Cons: Where It Falls Short

• No native outreach layer. FullEnrich enriches records but does not send emails, run sequences, or manage cadences. You need a separate tool — Instantly, Outreach, Apollo sequences — to actually reach prospects.
• No buying signals or intent data. FullEnrich tells you how to reach a contact, not whether their company is in market, so timing has to come from another tool.
• No native Salesforce connector. HubSpot has a native sync, but keeping Salesforce or other CRM records enriched requires Zapier, Make, n8n, or API work.
• APAC and LATAM hit rates drop to 50–60%. If your ICP concentrates in Southeast Asia, Latin America, or non-English-speaking markets, waterfall coverage thins significantly.
• The provider list is narrower than Clay's. As of September 2026, FullEnrich cascades 25+ sources, while Clay can route across 75+ providers, which can help on edge cases such as niche industries, SMB contacts, and non-English names.
• Mobile numbers are expensive in credits. At 10 credits per mobile number versus 1 per work email, phone-heavy workflows use up a 1,000-credit Pro allocation in 100 lookups.

FullEnrich vs Clay vs Apollo

The enrichment category has fragmented into pure-enrichment tools (FullEnrich, Hunter), orchestration platforms (Clay), and integrated prospecting platforms (Apollo). Here is how the three compare across the dimensions that matter for enrichment decisions in 2026.

The honest take on each option

FullEnrich wins on pure enrichment hit rate at the lowest price point. It is the right choice if enrichment is all you need and you already have buying signals and outreach handled separately.

Clay offers the most flexible enrichment orchestration (75+ providers) but requires significant setup time, starts at $167/mo for paid plans (as of September 2026), and has a steep learning curve. It is the right choice for technical RevOps teams who want maximum customization and already know how to build Clay tables.

Apollocombines enrichment with outreach sequences and a proprietary database, but its single-source enrichment hit rate is lower than waterfall tools. The built-in sequencer is Apollo's differentiation, but its enrichment quality falls short of waterfall alternatives on enterprise targets.

Who Should Use FullEnrich?

FullEnrich is the right tool in one specific scenario: you are a contact data ops team or RevOps engineer who needs best-in-class email and mobile enrichment hit rates, you already have a separate signal monitoring tool and a separate outreach sequencer, and you want the enrichment layer to be as cheap and accurate as possible without platform overhead.

Use FullEnrich if:

• Your ICP is US or EU enterprise and you are optimizing enrichment hit rate above 70%.
• You have 3+ people running enrichment and per-seat pricing from tools like Lusha is becoming expensive.
• You already use Clay, Apollo sequences, or a dedicated signal tool and just need a better enrichment provider in that stack.
• You want API access and programmatic enrichment without paying enterprise minimums.

Do not use FullEnrich if:

• You need buying signals or outreach sequencing in the same product. FullEnrich provides neither.
• Your ICP is heavily APAC or LATAM where hit rates drop to 50–60%.
• Phone-verified mobile numbers for UK/EMEA cold calling are your primary need — Cognism Diamond Data is more accurate for that specific use case.
• You run Salesforce and want enrichment to update records automatically. HubSpot has a native sync, but Salesforce needs Zapier, Make, n8n, or API work.

Bottom line: FullEnrich is one of the most cost-effective ways to add multi-source email and mobile enrichment to an existing stack, with transparent credit pricing and a free trial that makes it easy to test. Budget carefully for mobile numbers at 10 credits each, and plan for integration work if your CRM is Salesforce.
