What MillionVerifier does
MillionVerifier is a cloud-based email verification SaaS platform operated by GBD Software as a Service Private Limited Company, a privately held Hungarian company founded in 2016. The platform verifies email addresses at three layers: free single-email checks via web UI, bulk file verification for lists of CSV/TXT/XLSX uploads, and real-time or batch verification via REST API for programmatic integration into signup forms, CRMs, and ESPs. Its core technical components include Smart Verify (a verification approach augmented with actual life-sending data to reduce false positives and false negatives), a Catch-All Verifier that resolves 30-40% of risky emails that standard verifiers misclassify, advanced greylisting handling, and EverClean, an automated daily verification service that continuously cleans contacts inside connected ESP accounts (Mailchimp, HubSpot, ActiveCampaign).
The platform is sold primarily through a self-serve product-led growth model with a free 100-credit trial and credits-based pricing starting at $39 (10K emails) and scaling to $449 for 1M verifications, with discounts above 50M. Credits never expire and no credits are charged for Unknown or Catch-All results. A 100% money-back guarantee applies when hard bounce rates exceed 4% on verified emails. The customer base spans email marketers, outbound sales teams, SaaS product teams (signup validation), agencies, and resellers, served through 40+ native integrations plus a reseller/white-label channel. MillionVerifier is ISO 27001 certified, GDPR compliant, and reports 70,000+ business customers with a 4.6/5 Trustpilot rating.

No credits charged for Unknown or Catch-All results, only for Good and Bad (Invalid and Disposable) results. Credits purchased once and usable forever.
- Auto Top-up Subscription: Optional automated credit replenishment service. Users set a low-credit threshold and the system automatically purchases credits. Users who enable auto top-up receive 10% extra credits on each automatic purchase.
- Reseller/White-label Licensing: Partners can resell email verification services using the API at standard user pricing. Partners integrate with APIs (Single/Bulk) and sell the service under their own branding.
