Check if email domain is disposable

A disposable email address is a temporary email account that expires after a short period (usually minutes to hours). These are commonly used to bypass email verification systems, access free trials, or avoid giving out real email addresses. Popular services include 10minutemail, tempmail, guerrillamail, and mailinator.

Our database contains thousands of known disposable email domains and is continuously updated. We maintain high accuracy by monitoring new temporary email services and validating domain configurations. However, new services may take time to be detected, so we recommend combining this with other validation methods.

Our disposable email database is updated continuously. We monitor for new temporary email services, track domain changes, and remove inactive services. Updates typically happen multiple times per week, ensuring you're protected against the latest disposable email providers.

For normal usage, there are no strict rate limits. However, if you're planning to make thousands of requests per minute, please contact us at hi@hreflabs.com to discuss your use case. We want to ensure our service remains fast and reliable for everyone.
