Frequently Asked Questions
What is a disposable email?
A disposable (or temporary) email is a short-lived email address created to avoid giving out a real address. Services like Mailinator, Guerrilla Mail, and Temp Mail let anyone generate a throwaway inbox in seconds. They are commonly used to bypass signup forms, abuse free trials, and create fake accounts—which is why blocking them is critical for SaaS applications.
