Frequently Asked Questions
Everything you need to know about LeadVerifier
How does LeadVerifier work?
+
Upload a CSV of leads or enter them individually. Our engine verifies each website, validates emails, detects business signals, identifies technologies, and scores each lead from 0-100. Processing happens in real-time through your browser.
Is my data secure?
+
Yes. All data is stored securely with encrypted connections. AI analysis respects strict data privacy standards. You can delete your account and all data at any time.
What does the AI feature do?
+
The AI generates sales insights, classifies industries, identifies opportunities, and suggests sales angles for each lead.
How accurate is the verification?
+
Website and DNS verification is highly accurate (real-time HTTP checks and DNS lookups). Email verification checks format, domain, and MX records. Business detection and industry classification use pattern matching and confidence scores.
Can I process thousands of leads?
+
Yes! Upload a CSV with up to 50,000 rows. The batch processor handles them automatically with pause/resume support. Processing speed depends on your plan and batch size settings.
What file formats do you accept?
+
Currently we accept CSV files with column headers. Our column mapper auto-detects common field names (Company, Website, Email, Phone, etc.) and lets you manually map any column.
Do I need to install anything?
+
No. LeadVerifier is a web application that runs in your browser. The AI model downloads once and is cached for subsequent use.
Can I export my results?
+
Yes. Export any project's verified leads as a CSV file with all verification data, scores, and quality classifications included.
