Frequently Asked Questions
What does email validation check?
It validates email format (RFC 5322), domain existence (MX records), syntax errors, and common typos. Advanced validation can check if the mailbox exists without sending emails.
Can I validate multiple emails at once?
Yes, paste a list of emails or upload a CSV file for batch validation. Results show valid, invalid, and risky emails with detailed error messages.
Does validation guarantee email delivery?
No, validation confirms format and domain are correct, but cannot guarantee the mailbox accepts mail. Some servers block validation attempts for privacy.
What are disposable email addresses?
Temporary emails from services like Mailinator or Guerrilla Mail. The validator flags these as risky since they are often used for spam or fraud.
