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.
Why use a disposable email?
A throwaway address protects your real inbox in dozens of everyday situations.
Forum & comment signups
Reddit clones, niche forums, and comment systems all want an email. Use a disposable one and walk away when you're done.
Download gates & file hosting
"Enter your email to download" pages, lead-magnet PDFs, and file hosts that require verification — all work with a temp address.
Account activation
Most sites send a confirmation email when you sign up. mail.cx receives those messages in real time via SSE, usually within a second.
Newsletter & promo signup
Want the 10% off coupon without 6 months of marketing email? Disposable mail gets the discount code, your real inbox stays clean.
Free trials without commitment
Try a SaaS free trial without giving your real address. If the product isn't for you, no autorenew nag, no breakup email.
Public Wi-Fi terms-of-service
Café and airport Wi-Fi often demand an email before letting you online. Skip the spam list — paste a disposable address and connect.
Suspicious or untrusted sites
Sketchy promotions, contest entries, or sites you're not sure about. Don't hand them your real email — give them a temp one.
Privacy-first account creation
Sometimes you just don't want a real identity attached. Disposable email keeps the account creation paper trail short.

How mail.cx is different
Three things you should know about our temporary email service before you pick one.
Real-time push, not polling
Most temporary email services check the server every few seconds. mail.cx uses Server-Sent Events to stream new mail to your browser the instant it lands — sub-second delivery instead of 5–30 second polling delay.
Self-destruct, not forwarded
Email aliases forward to your real inbox forever and stay tied to your real identity. A mail.cx temp mail inbox is independent, expires automatically, and leaves no link back to a real account. Use it and walk away.

mail.cx is fully free for personal use. The inbox carries no ads, no tracker, no signup, no credit card — every disposable email feature you actually need, at zero cost.
