What does FullEnrich do?

- Offers people and company search, reverse email lookup and bulk CSV enrichment.
- Provides a REST API with webhook or polling results, an MCP server for Claude, ChatGPT and Cursor, and agent skills on GitHub.
- Includes unlimited users on every plan, with per-user credit limits and low-credit alerts on Pro.

- 2FullEnrich runs its own waterfall across 25+ sources and verifies each email and phone
- 3Enriched contacts sync to HubSpot or return to Clay through the integration or API
- 4Clay routes verified contacts to a sequencer such as lemlist or Smartlead

Who is FullEnrich best for?
A good fit if you
- Teams that want waterfall enrichment through one API and one bill instead of contracting several providers directly.
- Teams with many users, since every plan includes unlimited users and pricing never scales per seat.
- Irregular usage: unused credits roll over for 3 months on monthly plans and 12 months on annual plans.
- Clay users who want FullEnrich's work email and mobile lookups inside a Clay table, on Clay credits or their own account.
Look elsewhere if you
- Teams needing native sync with CRMs other than HubSpot; FullEnrich lists HubSpot as its CRM integration.
- Phone-heavy workloads on a small budget, because each mobile number costs 10 credits.
- Teams wanting sequencing, signals or outreach automation in the same tool; FullEnrich focuses on enrichment and search.
- Enterprises needing custom SSO, BYOK or custom rate limits without a sales contract, as these are Enterprise-only.
Does FullEnrich integrate with Clay and your CRM?
- Clay
- Native Clay integration. Clay lists a Clay-built FullEnrich integration with two actions: Find Work Email with FullEnrich (from name and company domain or name) and Find Mobile Phone with FullEnrich. Both run on Clay credits or your own FullEnrich account. (source)
- Integrations
- FullEnrich lists a native HubSpot CRM integration, Clay, Zapier, Make and n8n, plus an MCP server and connectors for Claude, OpenAI, Manus and OpenClaw, and a REST API. It does not list native sequencer integrations; you route results through Clay or automation tools. (source)
- GDPR
- FullEnrich's privacy and legal centre states SOC 2 Type II certification, GDPR and CCPA compliance and a public DPA covering GDPR Article 28. It says data is hosted in the EU, transfers outside the EEA and UK use Standard Contractual Clauses, waterfall results are deleted from customer accounts after three months, and it does not keep its own database for waterfall enrichment. It acts as processor for waterfall enrichment and as controller, relying on legitimate interests, for People and Company Search. Individuals can opt out through its portal. (source)
- Data coverage
- FullEnrich says it queries 25+ data sources in its waterfall, that its search covers 800M people and 50M companies, and that its average email find rate is about 80%, varying by region and seniority. It also says roughly 30% of raw data is removed by verification. These are vendor figures. (source)
