While we don't verify specific claims because reviewers' opinions are their own, we may label reviews as "Verified" when we can confirm a business interaction took place. Read more

To protect platform integrity, every review on our platform—verified or not—is screened by our 24/7 automated software. This technology is designed to identify and remove content that breaches our guidelines, including reviews that are not based on a genuine experience.

Written by the company

BillionVerify is a professional email verification service that helps businesses validate email addresses with 99.9% accuracy before sending. Bad email data costs businesses money.

What we detect: - Invalid and non-existent email addresses - Disposable and temporary emails - Role-based addresses (info@, support@, admin@) - Spam traps that can get your domain blacklisted - Catch-all domains that accept any address How businesses use BillionVerify: - Clean subscriber lists before email campaigns to reduce bounce rates - Verify user emails at signup to block fake registrations - Validate prospect data before sales outreach - Maintain list health with regular bulk verification We integrate with 25+ platforms including Mailchimp, HubSpot, Salesforce, Klaviyo, SendGrid, Zapier, and Make.
