Architecture that enables data handling according to types of social relationships. A social graph is used to categorize the types of the social relationships of the tagged messaging users. The social graph can include social relationship categories for friends, family, coworkers, and blocked individuals of the recipient, for example. The social graph can also include metadata related to the tagged users. The metadata defines the social relationship of the tagged users to the recipient. Delivery of messages to the recipient from the tagged messaging users is managed based on the social graph. Delivery management can include blocking messages, allowing the messages through, or delivering the messages with high or low priority, for example. Email messages can be delivered to respective email locations based on the social graph. User information can be imported and/or mined from external sources to augment the social graph.
