MillionVerifier is an email verification platform offering high-accuracy verification services for bulk email lists. It ensures clean email databases by identifying and removing invalid, disposable, and inactive emails. The platform offers bulk email verification, real-time verification, and API integration for continuous monitoring.
MillionVerifier has built a strong reputation as one of the most accurate email verification services on the market, trusted by over 70,000 businesses. Founded by deliverability expert Tamas Szabo, the platform focuses on protecting sender reputation by removing invalid, disposable, and risky emails before they damage your domain. With a claimed 99%+ accuracy rate and a unique money-back guarantee on risky emails, it positions itself as a low-risk choice for companies that rely on email outreach.
The platform covers the full spectrum of verification needs. You can upload CSV, TXT, or XLSX files for bulk cleaning, use the REST API for real-time verification at signup, or set up EverClean to automatically verify new subscribers inside your ESP every day. MillionVerifier also detects catch-all addresses, temporary emails, and role-based accounts at no extra cost. The 17+ one-click integrations with tools like Mailchimp, HubSpot, ActiveCampaign, and SendGrid make it easy to plug into existing workflows.
Pricing is straightforward and credit-based. An one-time purchase of 10,000 verifications costs $19, 100,000 verifications run $99, and 1 million verifications are $389. Credits never expire, and volume discounts are available above 50 million. The EverClean automated cleaning service requires custom monthly pricing, which some users find less transparent. Still, the per-credit cost is among the most competitive in the category, especially for high-volume users.
MillionVerifier also includes several value-adds that set it apart. Every user gets free lifetime access to EmailAcademy PRO, a full deliverability curriculum. The support team responds in under an hour, even on weekends. And the platform is ISO 27001 certified and GDPR compliant, with a DPA available on every plan including the free tier. These extras make it a strong choice for agencies and enterprises that need both accuracy and compliance.
The main drawback is the lack of transparent pricing for the EverClean feature, which requires contacting sales. Some users also note that the interface, while simple, could benefit from more advanced reporting. But for core email verification, MillionVerifier delivers consistent, reliable results that keep bounce rates low and inbox placement high.
Bottom line:: If you need a high-accuracy, budget-friendly email verification tool with real-time API capabilities and strong integrations, MillionVerifier is a top contender. It's especially well-suited for marketing teams, sales development reps, and agencies that send large volumes of cold email and need to protect their domain reputation. The money-back guarantee on risky emails adds an extra layer of confidence that few competitors offer.
