Frequently asked questions
How does the disposable email checker work?
The tool compares the domain of the email address you type against a curated list of known disposable and temporary email providers. Everything runs locally in your browser — the email is never sent anywhere.
Is my email address sent to any server?
No. The check happens entirely client-side using JavaScript. Your email address never leaves your browser.
What counts as a disposable email provider?
Services like Yopmail, Mailinator, TempMail, GuerrillaMail, 10 Minute Mail and similar providers that let anyone create a throwaway inbox without registration, typically used to bypass free trial or signup restrictions.
Can this catch every disposable email domain?
No list is ever 100% complete since new disposable domains appear constantly. This tool catches the most common and widely used providers, but for production-grade coverage with automatic updates, an API-based solution is recommended.
Is there an API version of this tool for my website or app?
Yes, an API version is planned so businesses can validate email addresses automatically at signup, with a continuously updated domain list and higher accuracy than the free browser tool.
