Even better is to explicit specify standard output as tape archive ('-f
-').  If you don't specify which tape archive to use, tar will use a
'compilation dependent default' (quoting the manual), which may be some
different file than standard output (for example a tape device).

And it is always good to mark the end of options ('--'), as there might
exist csv-files which names start with two dashes,
e.g. '--file=file.csv'.

cd my_directory && \
tar -cj -f - -- *.csv | uuencode file.tar.bz2 | mailx -s Subject

Or, if you want to use gzip rather than bzip2:

cd my_directory && \
env 'GZIP=--best' tar -cz -f - -- *.csv | uuencode file.tar.gz | \
mailx -s Subject
