Using the same data source for an Envelope mail merge is probably the best
option.
The alternative of adding an envelope to the mail merge main document and
inserting the necessary fields in that envelope will result in the envelopes
being alternated with the letters and unless you have a printer that can
successfully handle such a mixture, it would be necessary to execute the
merge to a new document and then print all of the letters and all of the
envelopes. While a macro could be written to separate those to print
operations, just using the same data source for an Envelope mail merge would
seem to be the simplest method.
