This email is a fraud security feature custom to CM.
It is designed to alert someone that their vaulted card has been used to send a package to a "new" address. It is triggered the 1st time a user places an order that uses a vaulted credit card or ships to an address other than that on their account.
Please note, ANY change to a shipping address will be seen as new. The system will suggest a corrected address, including the addition of the additional 4 digits on the zip code (e.g. 55123-4567) and, if you accept the suggested update, the system considers that to be a new address.
The notification may be disregarded if the change was intentional and accurate.
