Hello Chris,
Creative COW partners with email providers such as Hotmail in Junk Mail Feedback Loops. These services allow us to close accounts which set our email as spam. When a user, such as yourself marks our email as spam we discontinue sending all emails to that user, and close their account. This way we are not continued to be marked as spam and our mail servers are not blocked by service providers.
It appears that you marked one of our emails, or newsletters as spam, so your account – associated with the cch99@hotmail.com email address – was closed.
Abraham
