What is Tomba

Tomba.io finds, verifies, and enriches professional email addresses and phone numbers across a database of 280M+ contacts, covering 81% of B2B domains with a stated 98% delivery rate. It's built for SDRs, BDRs, RevOps teams, and GTM leads at mid-market and enterprise companies who need clean contact data without manual research. The standout capability is reverse email lookup — feed it an email address and it surfaces the owner's identity, company, and social context, which is useful for inbound enrichment workflows that most email finders ignore. Bulk CSV processing lets teams run thousands of lookups in one pass, and the public API plus MCP server support means it can slot into automated pipelines or agent-driven workflows without friction. Where it falls short: phone data costs 10 credits per row versus 1 for email lookups, so high-volume phone enrichment at the Basic or Growth tier burns through credits fast.

Our verdict

Vanderbuild take

Tomba is a focused email finder and verification tool that earns its place in the Data & Discovery stack for SDR/BDR teams and RevOps operators who need reliable contact data without paying Apollo or ZoomInfo prices. The agentic story here is real — Tomba ships a native MCP server, which means you can wire it directly into AI agent workflows or use it as an orchestration layer for automated prospecting pipelines without building a custom wrapper. Budget tier 3 is accurate: at $8.90 per 1,000 credits and phone lookups burning 10 credits per row, costs climb quickly once you're running high-volume phone enrichment at scale, so model your credit consumption before committing to a tier. The integration surface is wide — Zapier, Make, Pipedrive, and SDKs across eight languages — but native CRM sync is not listed, so teams expecting a one-click HubSpot or Salesforce push will need to route through Zapier or build their own.
