All of a contact's information is shown in a comprehensive profile view. Information on profession, department or company can also be saved here, in addition to general information. In addition to this master data, sem.Addressbook also offers the possibility of keeping an activity log for each contact. With this log, all activities related to a contact can be saved, such as calls, emails or invitations. This type of logging is especially advantageous in the case of address books which are accessible by multiple people, such as customer or supplier lists.
