Embodiments are directed towards selecting for display at a client device focused advertisements within a mail message client based on a user's categorization of mail messages, including spam messages. Messages may be classified by a message classifier and placed into different message folders. Actions of the message recipient on the received messages are then monitored and used to determine a spam advertisement factor. If the spam advertisement factor exceeds a threshold for a given message, then the given message may be further examined to determine a focus of the message. The focus may then be used to select an advertisement for display to the recipient.
