A contact is defined by any name or email address you've added to your account. Your monthly bill is a combination of the pricing plan you've selected, plus the number of active contacts in your account. If your number of active contacts increased during the last billing period, you will move to a higher billing level. These charges will be reflected in next month's bill. You can check your pricing plan from the My Account page. You are not charged for your unsubscribed contacts or any contacts you have on file without an associated email address.
