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.
Our free email checker performs comprehensive email validation in seconds — no registration required, no daily limits, with real-time DNS queries for up-to-date results
Type a single email address, paste up to 500 emails in bulk mode, or upload a CSV/TXT file.
Our system validates email format against RFC 5322 standards, performs real-time DNS and MX record lookups to verify the domain can receive mail via SMTP, 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). Note that catch-all domains may show as valid even if the specific mailbox doesn't exist.
A powerful free email validation tool and bulk email verifier — everything you need to assess email deliverability, from format checks to DNS verification
We perform real-time DNS lookups to verify that the email domain exists and has valid MX (Mail Exchange) records configured for receiving email via SMTP. No MX records means the domain can't receive 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.

From marketers cleaning their lists to developers validating user input
Email lists naturally decay at 22–30% per year as people change jobs and abandon addresses. High bounce rates damage your sender reputation with providers like Gmail and Outlook, risking domain blacklisting. Regular email validation can improve open rates by 10–20% and keep bounce rates below the industry-recommended 2% threshold.
Validate email addresses at the point of signup to prevent fake registrations, reduce fraud, and ensure you collect real contact information. Block disposable emails and catch typos before they become invalid accounts.
Verify prospect email addresses before outreach to improve response rates and avoid wasting time on invalid contacts. Identify role-based addresses that may have lower conversion rates compared to personal business emails.
Detect disposable email addresses commonly used for fraud, abuse, and fake account creation. Verify that email domains are legitimate and have proper mail infrastructure configured, adding an extra layer of trust verification.
