To send mail I usually use the mail command. It is Fairly simple to use. And fits into a script well.
mail -s "This is my subject" -b "let's bcc some people here" -c "we'll CC some people in here" thisis@whoIamsendingit.too <<EOF
here I type
the many lines of the message
followed by a . on a line by itself.
Sorry about the delay... I totally missed when this came up again.
