Frequently Asked Questions

Does it verify the email actually exists?
We check format, domain, and MX records. Full mailbox verification (SMTP handshake) is not performed as most servers block this.
What is a disposable email?
Disposable emails are temporary addresses from services like Mailinator, Guerrilla Mail, etc. They're often used to bypass sign-up requirements.
Is this free?
Yes, free for individual lookups. Bulk validation via API requires a paid plan.
