MillionVerifier positions itself as the budget option in email-list verification — bulk cleaning and a real-time API built for teams sending high volumes who want the lowest per-check price rather than the most feature-heavy suite. Most of what comes up about it lives inside outbound and cold-email playbooks, where it's named as one line in a larger deliverability stack: clean the list, verify before sending, then watch bounce and reply rates. Practitioners reference it specifically for bulk list-cleaning ahead of a campaign launch and for holding verification rates above a working threshold before a send goes out. Its presence in that conversation is steady and practitioner-level rather than wide.

Business Profile
Founded in 2016, MillionVerifier operates at a small-team scale, with six employees in the record, and remains focused on email verification. Its business combines bulk list cleaning with real-time checks and integrations into email marketing tools. In October 2026, founder and CEO Tamas Ham-Szabo described an internal restructuring that moved service operations to Southern Vector Limited while keeping ultimate ownership, leadership, and the team unchanged. Existing credits, API keys, integrations, and prices continued through the change. Current product communication emphasizes verification within customers’ existing marketing workflows.
Agent Readiness
Measures how easily your agents can build on it — API, MCP, CLI, SDK, docs depth. Methodology →
MillionVerifier's documented agent-facing foundation is its API. Software can check individual addresses in real time or submit files for bulk verification and retrieve results. These endpoints give agent workflows a defined verification step between finding contacts and preparing outreach. The public documentation centers on programmatic email checks, with API-key authentication and request examples; no separate agent product is established in the supplied record.
