MillionVerifier review
A broad email verification toolkit with flexible credits, but a relatively high entry price.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
MillionVerifier is an email verification service for marketers, sales teams, developers, and organizations maintaining email databases. It combines bulk list cleaning with real-time address checks, supporting uploaded or pasted lists, common spreadsheet formats, and API-based verification. Its feature set covers disposable and role-based address detection, catch-all verification, and refunds for emails that cannot be verified with certainty. Teams working across web and API workflows can use it for both one-off list work and ongoing validation.
The published plan is straightforward: 10,000 verification credits cost $39 as a one-time purchase. Credits are pay-as-you-go and do not expire, which suits teams that prefer not to commit to recurring monthly plans or that verify lists irregularly. There is no permanent free plan. The main tradeoff is price: the listed entry point is less attractive than lower-cost alternatives, particularly for buyers focused primarily on minimizing cost per credit.
MillionVerifier’s strongest fit is an ESP-connected team that wants several ways to maintain list quality. Integrations include Mailchimp, Mailgun, Mailjet, Elastic Email, Campaign Monitor, ActiveCampaign, Zoho CRM, Reply, GetResponse, HubSpot, AWeber, MailerLite, Drip, SendGrid, and Intercom. EverClean adds automated daily verification, while the API supports real-time single-email checks plus bulk file upload and result retrieval. Choose it when recurring hygiene, integration coverage, and multiple verification workflows matter more than the lowest listed price. Buyers seeking a permanent free option or recurring monthly plans should look elsewhere.
