Free Online Email Verification Tool
Check email format, domain, MX records, disposable & role-based detection. Bulk verify up to 500 emails at once — free, no signup required.
Type a single email address, paste up to 500 emails in bulk mode, or upload a CSV/TXT file. Use our email permutator to generate possible addresses from a name and domain.
Our system validates email format against RFC 5322 standards, performs real-time DNS and MX record lookups, detects disposable emails from 500+ providers, identifies role-based addresses, and calculates an email deliverability score from 0 to 100.
Get a clear Valid / Risky / Invalid status with a deliverability score based on 5 weighted factors: format (+20), domain (+20), MX records (+30), not disposable (+20), not role-based (+10).
We perform real-time DNS lookups to verify that the email domain exists and has valid MX (Mail Exchange) records configured for receiving email. We display all MX records with their priority levels — results are always up-to-date using live DNS queries.
Detect temporary and throwaway email addresses from over 500 known disposable email providers including Mailinator, Guerrilla Mail, TempMail, YOPmail, and more. Protect your signup forms and mailing lists from fake addresses.
Identify role-based email addresses like info@, admin@, support@, sales@, and noreply@ that are tied to functions rather than individuals. These typically have lower engagement rates for marketing campaigns.

Verify prospect email addresses before cold email outreach to improve response rates and avoid wasting time on invalid contacts. Use our B2B lead generation tools to find qualified prospects, then verify their emails before reaching out.
