Systems and methods for automated contact updating based on content communications are disclosed herein. A rule is retrieved from a rules database, the rule defining criteria for identifying contact-related data within a content item electronically communicated from a source account to a destination account. Based on the rule, the contact-related data is identified within the content item.

Based on the contact related data, a determination is made as to whether the contact entry should be updated. In response to determining that the contact entry should be updated, the contact entry is updated in the contact database based on the contact-related data.
