Hunter's free Disposable Email Checker tells you instantly if an email address belongs to a temporary or throwaway provider; a fast way to check if an email is fake before it reaches your list.

No login is required, and you can use it as a stand-alone temporary email detector or as a first pass before running a full verification.

A disposable email address is a temporary inbox someone creates for short-term use, usually to sign up for something without giving out their real address. Services like Mailinator, Guerrilla Mail, 10 Minute Mail, and YOPmail generate these addresses, and most stop working minutes or hours after they're created.

Check any address in a few seconds:

The Disposable Email Checker only looks at the domain to tell you if it belongs to a temporary provider.

It doesn't confirm that a specific mailbox exists or can receive mail.

To find out if an address is actually deliverable, run it through the Email Verifier, which checks the domain, MX records, and SMTP connection in addition to disposable detection.

See What checks are performed on an email with the Email Verifier? for the full breakdown, and What are the possible verification statuses for an email? to see where Disposable fits among the other statuses.

Yes. It's completely free, with no signup and no limit on how many addresses you can check.

This tool checks one address at a time. To screen an entire list, use the Bulk Email Verifier, which flags disposable addresses as part of a full validity check.

No. Free webmail providers such as Gmail, Outlook, and Yahoo are not disposable; they’re permanent personal inboxes. The checker tells you when an address is from a free webmail provider so you don’t confuse it with a temporary one. If you need to verify whether a specific webmail address is valid, use the Email Verifier.

For a full deliverability check beyond disposable detection, use the Email Verifier.
