BillionVerify
BillionVerify is a professional email verification service built to solve one problem: bad email data costs businesses money. Every bounced email hurts sender reputation, wastes marketing spend, and skews campaign analytics. We built BillionVerify to give teams of every size access to accurate, fast, and affordable email verification. Since launch, our platform has processed over 1 billion email verifications for businesses across 200+ countries, covering everything from single API lookups at signup to bulk list cleaning of millions of records. Invalid email addresses are the hidden tax on email marketing. They inflate list sizes, trigger bounces, damage sender scores, and ultimately reduce the number of real people who see your message. Our mission is to eliminate that waste. We built a multi-step verification pipeline that goes beyond surface-level syntax checks. Every email submitted to BillionVerify passes through format validation, DNS and MX record lookups, SMTP connection testing, and mailbox confirmation. This layered approach is why we maintain 99.9% accuracy across providers worldwide. We also believe verification should be accessible. That is why we offer 600 free credits every month, plus a 20-credit bonus every day you log in, API pricing starting at $0.001 per email, with volume discounts down to $0.00014 per email, and a pay-as-you-go model with no monthly minimums. Whether you are a solo founder cleaning a prospect list or an enterprise team verifying millions of records per month, BillionVerify scales to fit.
