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.
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.
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.
