I completely second byoung2's comment.
When we say email , the thing we refer to would be free email services for personal use or inbox hell at work.
The same question without Gmail,Yahoo mail and other is easier to answer.
SMTP might be here to stay, but a low cost protocol independent messaging protocol with an Identity layer can and will come along.
Why does no official comm happen on email? No ID validation.
Maybe PKI can help.
Solution will either be use case by usecase or platform change like FB or chat
