Word 2007 E-mail Merge with PDF Attachment:

I have created an E-mail merge in Word 2007 to 130 recipients that works fine. I want to attach a PDF but cannot find a way. I can drag the PDF into the e-mail but it just inserts PDF icon, not the PDF file.

What I want to do is:

Use Word to do an email merge to 130 recipients.
Use an Excel file as data table for the e-mail addresses.
Write the body of e-mail in Word.
Have the PDF's attached to each email.

Can anyone help?

Thanks!
