Computing systems, database systems, and related methods are provided for managing data pertaining to electronic messages. A database system includes a database including a first object having a plurality of content fields corresponding to a first instance of an electronic message configured for a first communication channel and a server coupled to the database and a network to create a second database object corresponding to a second instance of the electronic message configured for a different communication channel, create a multichannel data structure in the database maintaining an association between the first and second objects, automatically populate a subset of content fields of the second object with values copied from the first object based on a mapping between the two communication channels, and thereafter use the second object to generate a version of the electronic message to be communicated to a recipient using the second communication channel.
