Email last reply body

Jun 26, 2014 at 12:55 AM
How do I grab only that last body of the email the user reply with. So imagine a long email chain and then the last person replies with the text below and no signature. How do I just grab HELLO! without knowing that is what then sent. I want to always be able to know that is the last reply and not the whole chain of the email body. MIME parts maybe?
