Syntax Check
We validate the email format against RFC 5322 standards, checking for proper local part, @ symbol, and domain structure.
Email Validator
Validate email addresses with real DNS lookups. Check syntax, MX records, disposable domains, and role-based addresses in real-time.
Why Validate Your Email List?
Email validation is essential for maintaining a healthy sender reputation and maximizing your email marketing ROI. Invalid, disposable, or role-based email addresses can lead to high bounce rates, spam complaints, and ultimately, poor deliverability. Our validator performs real DNS lookups to verify MX records and comprehensive checks.

How Email Validation Works
Our production-grade validation performs real DNS lookups and comprehensive checks on each email address.
Real MX Lookup
Actual DNS query to verify the domain has valid mail exchange records and can receive emails. No simulations.
Disposable Detection
Cross-reference against 200+ known temporary email providers like Mailinator, Guerrilla Mail, and more.
Role-Based Check
Identify generic role addresses (info@, support@, admin@) which often have lower engagement rates.
Frequently Asked Questions
What file formats are supported?
You can upload TXT files with one email per line, or CSV files where emails will be extracted from any column. You can also paste emails directly, separated by commas, semicolons, or newlines.
Are the MX lookups real?
Yes! We perform actual DNS queries to check for MX records. This is production-grade validation, not simulated results. You'll see the actual MX server for each valid domain.
Are role-based emails invalid?
Not necessarily. Role-based emails (info@, support@) are legitimate but typically have lower engagement and are better suited for transactional rather than marketing emails.
Can I stop validation midway?
Yes! Click the "Stop Validation" button to halt the process. You'll keep all results that have been processed so far and can export them.
