About

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.

About

Bulk Email Checker has verified more than 12 billion addresses since 2012 for over 400,000 customers. Real-time SMTP verification delivers 99.7% accuracy by handshaking directly with mail servers rather than querying cached databases. Upload a CSV or TXT file to clean an existing list, or call the REST API to validate addresses at signup and checkout. Every result includes disposable detection, role account flags, catch-all handling, spam trap identification, domain typo correction, and MX server intelligence returning IP, hostname, location, ISP, and ASN. Pricing is pay-as-you-go from $2.95 per 1,000 verifications down to $0.000132 per address at 25 million. No monthly fees, no contracts, and credits never expire. Duplicates and unknown results consume nothing. High-volume users can switch to the Unlimited API for flat thread-based pricing from $250 per month with no per-email cost.
