Abstract: One or more computing devices, systems, and/or methods for adjusting recipients of a message are provided. For example, a trigger item may be detected in a first input field, of a messaging interface, corresponding to a body of a message. A list of user identifications may be generated and/or displayed. A first content item may be detected in the second input field following the trigger item. A second list of user identifications may be generated based upon the first content item and/or the second list of user identifications may be displayed. A first user identification may be selected by receiving a selection of the first user identification from the second list of user identifications. A first contact item associated with the first user identification may be entered into one or more second input fields corresponding to one or more recipients of the message.
