What makes an email 'risky'?
Risky emails include those from disposable or temporary email providers, addresses with catch-all domains, and emails that pass syntax but fail deeper checks.
Are my files secure?
Absolutely. Email Validator processes everything directly in your browser using client-side technology. Your files never leave your device, so your privacy is fully protected.
Do I need to create an account?
No account or registration is required. Just open the tool and start using it immediately. We don't collect your email or personal information.
Is there a limit on file size?
There's no hard limit imposed by the tool itself, but very large files may take longer to process depending on your device's capabilities. For most everyday needs, performance is fast and smooth.
Can I validate emails in bulk?
Yes, paste or upload a list of email addresses and the tool will check them all. Results show which emails are valid, invalid, or risky.
