Hunter.io Finds Emails.1Lookup Validates Perfectly.
Hunter.io is great for finding email addresses—but validation is secondary. 1Lookup is a specialized email validation platform that focuses on accuracy, speed, and deliverability. Built for businesses that need guaranteed inbox delivery and fraud protection.
Real-Time Validation
Hunter.io requires bulk upload and processing time. 1Lookup validates emails instantly in real-time with 120ms response times. Perfect for form validation, user registration, and checkout processes where speed matters.
Advanced Fraud Detection
While Hunter.io focuses on email discovery, 1Lookup specializes in email security. Our AI-powered fraud detection identifies disposable emails, spam traps, and suspicious patterns that Hunter.io misses.
