Disposable Email Checker

A disposable email checker tells you whether an email address comes from a temporary or throwaway provider. Hunter’s checker takes any address, looks at its domain, and matches it against a database of more than 180,000 known disposable and temporary email providers, all in a couple of seconds and with no signup.

A disposable email address is a temporary, often self-destructing inbox that someone creates for short-term use, usually to sign up for something without revealing their real address. Services like Mailinator, Guerrilla Mail, and 10 Minute Mail generate these addresses, which stop working minutes or hours later.

Paste the email address into the checker above and click Check email. We extract the domain and tell you instantly whether it’s a disposable or temporary provider. You can check as many addresses as you like, for free.

Yes, completely free with no limits and no account required. If you want to verify whether an address is actually valid and safe to send to, you can also use the Email Verifier, which includes disposable detection as part of a full check.

A disposable email checker only tells you whether an address comes from a temporary or throwaway provider. Email verification goes further: it confirms whether a specific address actually exists, accepts mail, and won’t bounce. For the full picture, run the address through the Email Verifier.

A disposable email checker tells you whether an address comes from a temporary or throwaway provider. A reverse email lookup does the opposite job: it starts from an email address and finds the person and company behind it (name, role, and social profiles). Use this tool to screen out fake signups, and the reverse email lookup when you want to know who an address belongs to.

Disposable addresses are commonly used to create fake accounts, claim free trials repeatedly, and abuse promotions. They also inflate your bounce rate and pollute your analytics. Filtering them out protects your sender reputation, keeps your data clean, and focuses your outreach on real, reachable people.

The checker covers more than 180,000 domains, including well-known providers like Mailinator, Guerrilla Mail, 10 Minute Mail, YOPmail, and Temp Mail, plus thousands of lesser-known and newly created throwaway services. The list is updated continuously as new providers appear.

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 know whether a specific webmail address is valid, verify it with the Email Verifier.

This free tool checks one address at a time. To screen an entire list, the Bulk Email Verifier flags disposable addresses alongside a full validity check, and the Hunter API returns a disposable flag on every verification so you can filter signups in real time.

No. The disposable check only looks at the address’s domain against our database, so nothing is ever sent to the address. It’s completely silent and safe to run on any address.
