different Auto Responder for Different queries

In my website, visitors can download free pdf or ebook. I am using Contact form 7 + email before Download + Wp Download Monitor for this to capture leads. I want to send auto responded email when any visitor download free file. But i have 5 different free PDF and want to sent 5 different auto responder on the basis of which file the visitor has downloaded.

Can it be possible in “mail 2” option in contact form 7 or should i use any other plugin? if so, which plugin? please help. Thanks in anticipation.
