Embodiments of the present disclosure provide methods, systems, apparatuses, and computer program products for executing an email communication import protocol in a selected group-based communication interface within a group-based communication system. The group-based communication system allows for receiving one or more email communication corpus associated with email communication accounts and parsing the email communication corpus to identify email communication account identifiers. The group-based communication system thereafter creates and transmits group-based communication interface invitations to the email communication accounts to allow access to the group-based communication interface. Upon access to the group-based communication interface, content from the email communication corpus may be included in the group-based communication interface.
