B2B Contact Finder

The contact finder analyzes a company's domain to predict the most common email format patterns (like firstname@company.com or firstname.lastname@company.com). It uses pattern recognition across thousands of B2B organizations to estimate which formats are most likely. For verified, deliverable email addresses, use Cleanlist's full enrichment platform.

Yes, the contact pattern finder is completely free with no signup required. It shows predicted email formats and company intelligence previews. For verified email addresses and phone numbers (confirmed via SMTP checks), you can sign up for Cleanlist's free tier which includes 30 credits.

Email format predictions are based on common B2B patterns and are typically accurate for 60-80% of companies. However, predictions alone cannot confirm whether a specific email address exists or is deliverable. Cleanlist's full verification checks each address against real mail servers for 98% accuracy.

This free tool predicts email patterns based on domain analysis. Cleanlist's platform goes much further: it verifies each email address via SMTP handshake, finds direct-dial phone numbers, enriches contacts with 40+ data points (job title, company size, tech stack, funding), and runs waterfall enrichment across 15+ data providers for maximum coverage.

The free contact finder shows email format predictions only. For verified direct-dial phone numbers and mobile numbers, sign up for Cleanlist's free tier. Cleanlist's waterfall enrichment achieves 85% phone coverage across B2B contacts — significantly higher than single-source providers.

Hunter.io and RocketReach rely on a single data source, which limits accuracy to 70-80%. Cleanlist uses waterfall enrichment — querying 15+ providers in sequence — to achieve 98% email accuracy and 85% phone coverage. This free tool shows format predictions; the full platform delivers verified, multi-source results.
