MillionVerifier is a specialized email verification service designed to help marketers, sales teams and agencies keep their email lists clean and improve deliverability. Operated by GBD Software as a Service Private Limited Company in the EU, it focuses on bulk list cleaning, single-email checks and real-time API verification so that customers can reduce hard bounces and protect their sender reputation.
The platform offers several ways to verify emails: single checks in the web app, bulk verification via file upload or copy‑paste, integrations with major ESPs and CRMs, and both single and bulk APIs. Its verification engine performs deep checks including syntax, domain and DNS validation, SMTP handshakes, catch‑all and disposable detection, greylisting re‑verification, typo correction and classification of results into Good, Risky and Bad categories. MillionVerifier markets a 99%+ accuracy rate backed by a 100% money‑back guarantee if hard bounces exceed a specified threshold.
Beyond core verification, MillionVerifier’s EverClean service automates daily list hygiene directly inside connected email marketing tools, unsubscribing or removing invalid and risky addresses without manual exports. The company also bundles free access to EmailAcademy PRO, a toolkit offering blacklist monitoring, inbox testing and educational content about email deliverability.
Founded in 2016, MillionVerifier positions itself as a low‑cost alternative to larger verification vendors, emphasizing very competitive, never‑expiring verification credits and volume discounts. Its customer base is heavily skewed toward small businesses and agencies that need to verify large volumes of addresses cost‑effectively, though it also serves mid‑market organizations. While reviews consistently praise its pricing and ease of use, some users note limitations around support responsiveness and occasional performance issues, making it best suited to teams that prioritize price and basic automation over enterprise‑grade SLAs.
