B2B Email & Phone Waterfall Enrichment
Grade: A — Score: 95/100
FullEnrich leverages advanced technology to aggregate contact information from over 20 premium vendors, ensuring high accuracy and coverage for email and phone data. Their unique verification processes, including triple email verification and advanced catch-all resolution, enhance data reliability.
The platform integrates seamlessly with existing workflows, allowing users to enrich inbound emails, sync with CRMs like HubSpot and Salesforce, and upload CSV files for manual enrichment. This no-code solution minimizes the learning curve for teams, enabling them to focus on sales rather than data management.
By addressing the risks associated with poor data quality, FullEnrich ensures that users only receive verified and actionable contact information. This reduces the likelihood of wasted outreach efforts and enhances overall sales performance.

Consider switching to Lusha: FullEnrich offers superior data accuracy and verification processes compared to Lusha.
FullEnrich estimates an average email and phone find rate of about 80%, but says results vary by industry, geography, and the completeness of the input record. Its mobile-number checks cover more than 40 countries, while deeper owner-name matching is documented specifically for US and Canadian numbers. The vendor says its phone verification can remove up to 29% of bad numbers returned by providers, so you should test your own territories with the 50-credit trial.
FullEnrich says unsuccessful lookups do not consume credits; credits are deducted only when verified data is found. A successful work email costs 1 credit, a personal email 3, a mobile number 10, and a reverse email lookup 1. Unused credits roll over for three months on monthly plans and 12 months on yearly plans.
FullEnrich can do both through People and Company Search and its waterfall enrichment workflow. Search provides vendor-reported access to 800 million people and 50 million companies, with more than 30 combined filters available in the web app and API. The Search database does not itself contain email addresses or phone numbers, so you enrich selected contacts when you need those details.
FullEnrich's 1,000-credit option costs $55 per month or $49 per month billed yearly and includes unlimited users, while Apollo Professional costs $79 per seat per month billed annually. FullEnrich focuses on pay-for-success waterfall enrichment across 20+ providers; Apollo combines its database with sequences, email campaigns, call recording, automated follow-up, and pipeline management. Choose FullEnrich for a focused data layer without seat fees, or Apollo when you want prospecting data and sales engagement in one platform.
FullEnrich provides a managed 20+ provider waterfall, with its 1,000-credit option at $55 monthly or $49 per month billed yearly. Clay offers a marketplace of 200+ data providers, Claygent research, signals, workflow orchestration, and a native sequencer; its data credits start at $0.05 and actions at less than $0.01. FullEnrich is the simpler choice for standardized contact enrichment, while Clay provides more control for teams willing to design and meter their own GTM workflows.
FullEnrich's current public product pages document contact search, enrichment, verification, APIs, MCP access, and data routing rather than a native CRM or complete sales-engagement suite. They do not document built-in multistep sequences, a dialer, or pipeline management, and several outreach integrations are still marked Soon. Use FullEnrich as the contact-data layer beside a CRM or sequencer when those execution features matter.
FullEnrich documents an active HubSpot connector, but its Salesforce evidence conflicts: the pricing table marks Salesforce integration as included while the dedicated integrations page labels it Soon and routes users to a request form. The published integration catalog does not document a native LinkedIn browser extension, although the API accepts LinkedIn profile URLs and CSV-based workflows can process exported prospect lists. Confirm the exact Salesforce or LinkedIn workflow before purchasing.
FullEnrich's current API documentation lists 60 calls per minute, up to 100 contacts per bulk enrichment or reverse-lookup request, and default queues of 100 concurrent jobs, which permits up to 6,000 contacts per minute. Search is synchronous, while enrichment and reverse lookup can return results through webhooks. A July 2026 FullEnrich blog post describes higher and conflicting limits, so production buyers should confirm the applicable throughput with FullEnrich before designing around it.
FullEnrich provides an MCP server that gives compatible AI clients structured access to prospect search and waterfall enrichment. Its integration catalog names Claude, OpenAI, Manus, and OpenClaw, and the MCP endpoint can be added as an AI connector. FullEnrich supplies verified contact data to the agent; it is not itself an autonomous outreach agent.
FullEnrich states that it is GDPR and CCPA compliant and SOC 2 Type II certified, with EU hosting and a public DPA. The DPA sets default storage at three months followed by automatic deletion, and the trust page says customer and enriched data are not reused for FullEnrich's own purposes. Compliance is not automatic: the customer remains an independent controller responsible for an appropriate legal basis, notices, consent where required, and due diligence on waterfall data providers.
