The Disposable Email Checker is an online tool designed to identify temporary/disposable email addresses. It helps website administrators, marketers, and community operators quickly determine whether a user's registration email is temporary, preventing spam registrations, reducing fraud, and improving user quality. All detection happens locally in your browser — email addresses are never uploaded to any server.

2. Click "Check" to start analysis
3. Review risk ratings and domain types for each email

Disposable email (also called temporary email) is a service that provides short-lived email addresses without registration. Users receive a temporary address for verification emails, then discard it. Common services include Guerrilla Mail, TempMail, and 10MinuteMail. While convenient, these services are often abused. Detection primarily involves comparing email domains against a known disposable domain database.
A disposable email is a temporary email address created for short-term use, typically to avoid exposing your real email when signing up for websites. These addresses expire quickly and are often used for spam registration or fraud.
Checking for disposable emails helps prevent spam registrations, reduce fraud, ensure users provide real emails for follow-up contact, improve email deliverability, and protect community quality.
This tool includes a database of thousands of known disposable email domains covering major temporary email services. Accuracy depends on database update frequency. Some newer temporary email services may not yet be listed.
Yes. Enter multiple email addresses (one per line) in the text area and click Check. Results show risk level and domain type for each address.
No. All detection happens locally in your browser. Email addresses are never sent to any server. The domain database is embedded in the page and works completely offline.
You can copy the domain database and detection logic from this page into your project. Extract the email domain and compare it against the disposable domain list. We recommend updating the list regularly.
