There are a lot of temporary email service arround us. For example, we have SpamBox, MintMail, 10 Minute Mail, and etc. You may refer to my previous post for more information.
However, most of the services are temporary and the email account will disappear after certain time, which means that you need to create another account when you need.

OtherInbox provide alternative solution. It let user to register for an account, but with unlimited email addresses. Let say your username is “username”, so any emails which send to address ending with @username.otherinbox.com will be forwarded to your account.
So, you may create different email account for different use. For example, you may create forum@username.otherinbox.com for forum purpose, while sales@username.otherinbox.com for buying or selling online.
Currently, you need to have invitation code to signup for new account. Thanks Download Squad for giving out the invitation link.

Hello,
Thanks for writing about OtherInbox on your blog. The TC50 conference in San Francisco earlier this month was a great forum to launch our new service to the public and we were really honored to be chosen to participate. We’d like to invite you to join our private beta that we announced at the conference, and we’re happy to extend the invitation to your readers as well! Because we’re in private beta, you need to have a special URL to sign up. This URL will work for 26 invitations (one for you and 25 for your readers) if you want to post as a followup on your blog.

Please let us know if you have any questions about the service. Thanks again!
