Tomba
AI-powered B2B email finder, verifier, and contact data platform
About Tomba
Tomba (formerly FindThat Email, findthat.email) finds and verifies professional email addresses and phone numbers from a name and company, a domain, a LinkedIn profile, or an article author. It indexes 80M+ company domains and 450M+ contacts from its own web crawl, returns the source URL for each address, and charges credits only for valid emails found. Access is through a web app, browser extensions, spreadsheet add-ons, a REST API with official SDKs, a CLI, and an MCP server.
Pros & Cons
Pros
- Credits are charged only when a valid email is found, and repeat searches in the same month are free
- Email verification credits are bundled with every paid plan instead of billed separately
- Each email comes with the source URL where it was published, which helps with GDPR audit trails
- Strong developer tooling: REST API, 10 official SDKs, a CLI, and an MCP server for AI assistants
- Wide coverage of entry points: domain search, author finder, LinkedIn finder, phone finder, and bulk CSV
- Rated 4.7/5 on G2 and Capterra
Cons
- Phone lookups cost 5 credits each, so phone-heavy workflows burn credits fast
- Credit-slider pricing with shared credits is harder to compare than fixed seat-based tiers
- Reviewers report lower plan limits than they would like and mixed data freshness
- Focused on finding and verifying contacts; no built-in email sequencing or outreach
- Accuracy and benchmark claims come from the vendor's own published test
