Frequently Asked Questions

Find Quick Answers

What does this email validator check?

Our validator performs four main checks: 1) Syntax validation against RFC 5322 standards, 2) Domain verification by checking if the domain exists and has MX records, 3) Disposable email detection using a database of temporary email services, and 4) SMTP server simulation to test if the email server would accept messages.

Is this tool 100% accurate?

While our tool provides comprehensive validation, no email validator can guarantee 100% accuracy. Some email servers may accept or reject messages differently in practice. Our tool gives you a reliable indication of email validity based on multiple verification methods.

Does this tool send actual emails?

No, our tool does not send any actual emails. The SMTP verification is simulated - we check if the domain's mail server would theoretically accept messages without actually sending anything. This ensures privacy and prevents spam.

What are disposable email addresses?

Disposable email addresses are temporary email accounts provided by services like Mailinator, TempMail, or Guerrilla Mail. They're often used for one-time registrations and may not be suitable for important communications. Our tool checks against a database of known disposable email providers.
