Many of you may be familiar with Mailinator and clones. They generate temporary anonymous email addresses and prove useful when signing up for services without giving up your personal email. However there are cases when I want to subscribe to a service and receive notifications. I may decide to unsubscribe later. Is there a need for a service that generates permanent anonymous email addresses?

I could generate a long term anonymous email address and have it forward email to my personal email account. Later when I want to stop receiving email from this account instead of looking for unsubscribe button I would delete the anonymous email address. This would solve the problem of unsubscribing from email subscriptions.
