What Is a Temporary Email?
A temporary email (also called a disposable email, fake email generator, or temp email) is a self-destructing email address you can use to receive email online without revealing your personal inbox.
Why Disposable Email Protects Your Privacy
Every time you share your real email, you risk spam, phishing, and data breaches. A disposable email acts as a shield — companies never see your personal address, and the inbox auto-deletes so there's nothing to leak.
How OpenInbox Works
Click one button to generate a free temp email address. Use it on sign-up forms, receive verification codes in real time, then let the inbox expire. No accounts, no passwords, no traces. Developers can also use our API for automated testing.
Common Use Cases
Testing app sign-up flows, downloading gated content, joining forums, redeeming one-time offers, or simply avoiding newsletter spam. Wherever a site asks for an email, a temporary email keeps your real inbox clean and your identity private.
