How many disposable email domains do you detect?
Our database includes over 100,000 disposable email domains and is updated daily. We track major services like Mailinator, Guerrilla Mail, TempMail, and thousands of lesser-known throwaway email providers.
What about new disposable email services?
We continuously monitor for new disposable email services and update our database daily. Our detection also uses pattern matching to identify newly created throwaway domains.
Should I block all disposable emails?
It depends on your use case. For paid signups or business leads, blocking disposables is recommended. For free newsletters, you might allow them but flag accounts for monitoring. The API gives you the data to make your own decision.
Does this validate the email format too?
Yes, the API includes basic format validation. For comprehensive email validation including MX records and mailbox verification, combine this with our Email Validation API.
What about corporate email aliases?
Legitimate corporate domains and email aliases are not flagged as disposable. We specifically target temporary/throwaway email services, not plus-addressing or corporate email systems.
How fast is the API?
Average response time is under 50ms. We use an optimized lookup system that can handle thousands of requests per second for real-time form validation.
