Mail F5 gives you a disposable email address. There is no need to register, simply visit Mail F5 and a random address will be given. You can also choose your own address.
You can give your email address to whoever you do not trust. You can view the email on Mail F5, click on any confirmation link, then delete it. Any future spam sent to the disposable email will be zapped by Mail F5, never reaching your mail box, keeping your mail box safe and clean.
Please see the FAQ below for more details about how our temporary email works.

Q: How can I view the spam folder?
A: There is no spam folder / spam box. All emails that arrive at Mail F5 are delivered to your inbox. If an email didn't arrive, it's most likely a problem on the other side, unless we're having a bad day... If you are a webmaster, Mail F5 can also be used to test if your site sends the emails out correctly.
Q: What is a Scrambled Address?
A: Since Mail F5 doesn't require account registration, anyone who knows the Inbox ID may have access to that inbox. So it's best to use a random address. To add protection, you can use the Scrambled Address feature. A Scrambled Address can only be know if the Inbox ID is known and you cannot use an Alias as an Inbox Id. The more hard-to-guess your Inbox ID is, the better your Alias will protect you.
Q: Do email addresses expire?
A: The current version keeps all incoming email for 1 hour. This means all addresses work all the time, they never expire.
When an email arrives at Mail F5, it waits in the quarantine ready to be picked up. If a user checks their inbox, Mail F5 will check the quarantine for new email. If found, the email will be instantly moved to the user's inbox. Else, emails will be deleted from the quarantine if they wait there for longer than one hour.
Once the email is in an inbox, it will be given 1 hour more, or until the user deletes it.
Emails that were never delivered to an active inbox are marked abandoned and are most likely spam.
(The older version of Mail F5 expired the address after 1 hour and bounced any inactive addresses.)
Mail F5 deletes all email that was delivered to an inbox after 1 hour.
We normally keep the logs turned off, this is because due to high traffic, our server does not have the resources required
Emails delivered to an inbox are treated with the most privacy, however, please note that anyone who knows your Inbox ID may access your inbox. Using a Scrambled Address will further protect your privacy. Please see the FAQ for further information.
