What Is a Temporary Email Address?
A temporary email address (also called disposable email or temp mail) is a short-lived inbox you use in place of your real address for sign-ups, trials, and one-off verifications. Once you're done, discard it — no spam, no tracking, no risk. Temp mail is ideal for receiving OTP codes, verification links, and test registrations without exposing your primary inbox. Learn how to create a temp mail address in seconds.
