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.
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.
How does email validation work?
Email Validator checks email syntax, domain MX records, and disposable email patterns. It doesn't send any emails to the address, so the recipient will never know their address was checked.
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.
Is this tool really free to use?
Yes, Email Validator is 100% free with no hidden fees, no premium tiers, and no usage limits. You can use it as many times as you want without ever paying.
