Email is like a cat. I don't know if it has nine lives, but people still use this form of communication even though it's been pronounced dead many times in recent years.
The general consensus among experts in online communication is that social media is killing the medium of email. Just as companies and organizations are getting pretty good at making their email newsletters look professional, it seems that more people are rendering email as the means of communication from a bygone era (sorry ConstantContact.com!).
