"Disposable email at it’s best. It’s like other webmail services, but there is no registration or password here. You only need a user name to read messages. What is that good for? Certainly not for private letters, but mainly for website registrations, where you don’t want to expose your real email address.
No setup, just send mail to any @MailNesia.com address. Useful if you don’t want to expose your real email address, for example at a website signup. It “clicks” on registration links in the email, completing your account validation at once."
Randomly generated email accounts. Great for those one off emails for a stupid registration.
Owning your own domain is also a great way to get temp emails. Just set up an account or alias that goes straight to junk mail folder
