How to attach a File in the email which is send through Campaign

Hi all,

I want to send the Mail through Quick Campaign  . In that mail i want to attach a File with that and send to many people.

In CRM 2015 the mail attachment cannot be added in that Campaign mail. I need to add attachment through Template  only.

If i add the attachment through templates in the mail that attachment is not going to all. Only the mail is going.
How to send a mail with attachment to all the person in that campaign process.

Please assist........
