# Cool idea of the day

By Roy Osherove July 24, 2003 In [Cool Tools](https://osherove.com/blog/category/cool-tools)

**Historical article** · Originally published July 24, 2003; technical details may be outdated.

 [Andres Aguiar](http://weblogs.asp.net/aaguiar/) sends word that  [Joel on Software](http://www.joelonsoftware.com/) sends word about [Mailinator](http://www.mailinator.com/).

_Need a disposable email address so you can sign up for some web site, quick? You've already got one, at Paul Tyma's clever_ [_Mailinator_](http://www.mailinator.com/)_. Just send an email to any \[email removed\]. Your email address already exists. Get your email sent here, THEN come check mailinator. Your mail will be waiting. More proof that great UI design is done by taking away, not adding things._
