One example: in 2003 we received a number of emails from concerned customers wondering if Sneakemail had been "hacked" because they were now receiving spam through the Sneakemail addresses they had created and used for Orbitz.com. A few days later the news broke that in fact Orbitz.com had been compromised and their users emails were now in the hands of spammers. Because our users had used Sneakemail, they not only knew why they were now receiving more spam, but they could easily stop it by simply deleting a single Sneakemail address.
SomeCompany.com wants your email address -- but you don't trust
them with it.
Log into sneakemail.com to create a new "Sneakemail address".
Name your new Sneakemail address -- "SomeCompany", for example.
Enter the email address you are hiding -- <firstname.lastname@example.org>
A new Sneakemail address is generated, something like
<email@example.com> -- give this to them
When mail is sent to <firstname.lastname@example.org>, we
forward it to <email@example.com>. The from header will
look something like this
From: "SomeCompany" <firstname.lastname@example.org>
Step 7 If you reply, it will be delivered back through our servers and your email address will remain hidden.
