Frequently Asked Questions

Find Quick Answers

What validation methods does this tool use?

The tool uses three validation methods: 1) Syntax validation (checks format against RFC standards), 2) DNS MX record lookup (verifies the domain accepts emails), and 3) Disposable email detection (checks against known temporary email services).

Can I validate multiple email addresses at once?

Yes, you can paste multiple email addresses (one per line) in the text area or upload a text file containing email addresses for bulk validation.

How accurate is the email validation?

The tool provides high accuracy by combining multiple validation methods. However, note that some valid emails might be marked as invalid if the domain's DNS records are temporarily unavailable or if the email uses a newly created disposable service not yet in our database.

Is my email data stored or shared?

No, all validation happens client-side in your browser. Email addresses are not sent to any server or stored anywhere. The tool works entirely locally for privacy protection.

What does 'disposable email' mean?

Disposable emails are temporary email addresses from services like Mailinator, TempMail, or Guerrilla Mail. These are often used for one-time registrations and may not be suitable for long-term communication.
