Use the address above on any signup form. New mail shows up here instantly.
10 minute mail services give you a disposable email address that self-destructs after 10 minutes. Mail.cx works the same way, but with a more practical 1-hour window — long enough to receive a verification code, confirm an account, or test an integration without your real inbox ever seeing it.
How long does a mail.cx inbox last?
Anonymous addresses on mail.cx last 1 hour from creation, with a 75-minute backend TTL on the raw email file. That's 6× longer than classic 10minutemail and gives you breathing room for delayed verification emails (some senders rate-limit and queue for 5–10 minutes). Pro users get custom domains with 7-day retention for emails sent to their own domain.

When 10 minute mail is the right tool
Use a 10-minute-mail-style address whenever the only thing standing between you and a service is an email verification step. Forum signups, software trial accounts, free Wi-Fi captive portals, contest entries, lead-magnet PDF downloads, beta access codes — anywhere a real email gets you marketing forever for one one-time verification.
Frequently asked questions
Is mail.cx really like 10minutemail?
Yes — same use case, longer window. Both give you a throwaway address for one-time verifications. mail.cx makes the window 1 hour instead of 10 minutes because some senders queue email and 10 minutes is too tight.
Can I get a longer-lasting address?
Anonymous inboxes are always 1 hour. For permanent addresses on your own domain (yourname@yourdomain.com), Pro adds custom-domain support with 7-day retention on every email.
Do I need to sign up?
No. The address is generated instantly when you load this page. Copy it, paste it into the form you're filling out, and the verification email shows up within a second of being sent.
Is the inbox really disposable?
Yes. After the 1-hour TTL the raw email file is deleted from storage. Without it, password reset and account recovery aren't possible on whatever you signed up for — so use this for accounts you don't plan to keep.
Do you sell or read my mail?
No. We don't sell, scan, or train any model on your inbound mail. After expiry it's gone — there's nothing left to read or sell.
Need a permanent inbox or your own domain?
Pro adds custom domains, REST API access, longer retention, and webhooks for teams and developers.
