I'm a bit perplexed by how you might be coming up with a Word doc which
exceeds [or even approaches] 8 MB in the first place
It suggests that you might be simply dumping a great deal of graphic content
in without properly processing it first. Should that be the case even
zipping the file will not compress it all that much - perhaps 20% - so if
the file is 8 MB even the compressed copy will be over 6 MB. That's still
far too large for most email attachments.
If you're simply inserting a lot of high resolution, large format images it
could certainly account for the massive result. If you want to (a) avoid the
problem & (b) retain the output quality of the images they really should be
worked through a good graphics editor, adjusted for resolution based on
intended print size & saved in the appropriate graphics file format before
being Inserted into the doc.
Other than graphics there are causes for bloated files but it's just
guesswork based on no more detail than you've provided - and most of them
don't cause that type of file size unless there's something seriously out of
control within the file.
