awk search file then pipe to mail

I need to write a script to search a static file (file1) in the form
Name Email
tim tfxo@gmail.com
bob bob@sss.com
and then mail them another file (file2) that is input from the command line.
The command line would be:
script.awk who file2 subject
and the result would be
mail -s subject who < file2
My centos is old and mail does not support -a
I am a novice so if there is a better way without awk please let me know.
Thanks in advance.

Please post a sample of the expected contents of file2

file2 is the file that I want to email. It is simply a text file, for example, it may be a monthly report, a list of users, a financial statement. But it will always be a simple text file that will become the body to the email message.
