SPAM and contacts

Hello -

I receive messages that are sometimes sent to my SPAM folder for review. When I mark these messages as NOT SPAM, the sender is automatically added to my contact list, which I don't want to happen.

For example, I may receive an order confirmation from an online purchase. I would like to mark the message as "NOT SPAM", but not have the email address of the online vendor added to my contacts list.

Is there a way to accomplish this?

Thanks!
