B2B Contact Finder
Find business contacts by company domain. Get predicted email formats, company intelligence, and enrichment previews — free.
About This Tool
The B2B Contact Finder helps sales and marketing professionals identify potential business contacts at target companies. Enter a company domain to instantly see the most common email format patterns used at that organization, along with a preview of the company intelligence data available through Cleanlist's enrichment platform. Unlike basic email guessers, the Contact Finder combines domain analysis with pattern recognition across thousands of B2B companies to predict the most likely email formats. It also previews the firmographic, technographic, and organizational data that Cleanlist can enrich — including company size, revenue range, tech stack, funding status, and direct phone numbers. This free tool gives you a starting point. For verified, deliverable email addresses and phone numbers confirmed through real-time SMTP checks and multi-provider waterfall enrichment, sign up for Cleanlist's free tier (30 credits, no credit card required). Every contact returned by Cleanlist is verified against real mailboxes, not just predicted from patterns.

How does the B2B contact finder work?
+
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.
Is this contact finder really free?
+
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.
How accurate are the predicted email formats?
+
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.
What is the difference between this tool and Cleanlist's full platform?
+
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.
Can I find phone numbers with the contact finder?
+
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.
How is this different from Hunter.io or RocketReach?
+
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.
Need production-grade data?
This free tool gives you a taste. Cleanlist delivers verified emails, phone numbers, and firmographic data from 15+ providers, at scale.
