What is disposable temporary email?
A disposable email — also called temp mail or temporary email — is a short-lived inbox you can hand out instead of your real address. mail.cx generates a disposable email instantly, pushes new mail to your browser in real time, and deletes everything when the inbox expires. No signup, no payment.
Use a temp mail address anywhere a form demands your email: signups, downloads, free trials, forum comments. The confirmation lands in your temporary email; spam, newsletters, retargeting, and phishing never reach your real inbox. Protect your privacy.
