  • CLASS Confirmation Email Has Changed (10/18/18):
    The format of the CLASS confirmation email for ad hoc orders and subscription orders was changed on 10/10/18. This change was implemented to prevent the possibility of CLASS sending an unreasonable number of emails to you. CLASS will now combine multiple order confirmation emails into one. This action has the potential of including both ad hoc and subscription orders in one notification. This will occur if more than ten orders are created within one minute. The subject line will contain a string of order and subscription numbers, while the body of the email will contain the information for each order. Unfortunately, some users running scripts dependent on information contained in the email may have been impacted by this change.

    If you have questions or a request to disable this feature please contact the CLASS Help Desk.
