Frequently Asked Questions

What is a temporary email address?

A temporary email (also called disposable email, throwaway email, or fake email) is an anonymous email address that expires automatically after a set time. It's perfect for signing up for services without exposing your real email to spam.

How does the email authentication validator work?

The email validator tests your mail server's DKIM, SPF, and DMARC authentication. Send an email from your mail server to the generated address, then view comprehensive authentication results including signature verification, sender policy framework checks, and domain alignment validation.

Is this service really free?

Yes! Both temporary email addresses and email authentication testing are 100% free. No registration, no credit card, no hidden fees. Create unlimited disposable email aliases and test email authentication as many times as you need.

How long do temporary email addresses last?

You can choose an expiration time from 15 minutes to 4 hours. After the selected time, the temporary email address and all received messages are automatically deleted from our servers.

What is DKIM, SPF, and DMARC?

DKIM (DomainKeys Identified Mail) validates email signatures. SPF (Sender Policy Framework) checks if sending servers are authorized. DMARC (Domain-based Message Authentication) ensures domain alignment. Together, they prevent email spoofing and improve deliverability.

Can I receive attachments with temporary emails?

Yes! Temporary email addresses can receive attachments. You can view and download them through your unique view link. In validator mode, attachments are also analyzed for potential security risks.
