If you need a quick temporary email address just search for
"temporary email service" on the internet.
They all work the same way. The free version usually doesn't require any registration. You just have to tell the email name and that's it.
- You can only receive emails with this temporary address, not send.
- Emails received are delete after a while (usually after an hour).
- These email addresses are not password protected.
- If you pick a name that is being used by other people you will see all their temporary emails. And they will see yours.
