I want an easy commandline way to read the file and blind copy send an email to the addresses in the file. So far, I have this working with just a plain send using the command below.

It may depend on your MTA (Sendmail, Postfix, Exim etc.)

"You must specify direct recipients with -s, -c, or -b."

   -b bcc-addr
        Send blind carbon copies to bcc-addr list of users.  The bcc-addr
        argument should be a comma-separated list of names.

You should replace newlines with comma:

cat mylist.txt | tr "\n" ","

Maybe something like this will work for you:

mail -s "Test E-mails" -b `cat mylist.txt | tr "\n" ","` 
my-generic at example.com < body.txt
