About the Disposable Email Checker

The Disposable Email Checker is a free tool designed to help you detect and block temporary or throwaway email addresses. These addresses are often used for one-time signups, bypassing restrictions, or avoiding spam, but they can also lead to fake registrations, abuse, and reduced email deliverability for your service.

By using this tool, you can:

• Protect your website or app from fake and low-quality signups.
• Reduce spam, fraud, and abuse from users with temporary email addresses.
• Maintain a cleaner, more engaged, and higher quality user base.
• Improve the effectiveness and deliverability of your email communications.

The checker relies on a frequently updated list of known disposable email domains. Simply enter an email address above and click "Check" to instantly see if it is disposable. For developers and businesses, integration options are available:

• Docker image for self-hosting the service.
• GitHub repository for source code and API documentation.
• npm package for direct integration into JavaScript/Node.js projects.

Whether you are an individual, a developer, or a business, this tool makes it easy to identify and block disposable emails, helping you keep your platform secure and your user base authentic.
