Embedding swf files in emails to be sent via Action Mailer



Is there anybody who can tell me if its possible to send swf files in
an HTML email via Action Mailer. I gained success in sending basic HTML
mail but couldnt send embedded swf files. Instead, the mail client at
the recipient end shows a blank mail when I send the swf file with
and tags. Any help would be appreciated.
