Please read this stackoverflow.com/questions/how-to-ask as it stands this is a very low quality question — Liath, Jan 15 '14 at 09:22
Ignoring the fact that this question has been asked alot already, what kind of user experience forces a user to type an exact string "No Email" just to point out they don't have one? — Kippie, Jan 15 '14 at 09:24
@Kippie, indeed. Why not just leave it blank and state the field is optional. :) — Moo-Juice, Jan 15 '14 at 09:25

You can combine your regex with an or expression |

var regex = "(.+@.+\..+|No Email)"

The validation part need some improvement (not RFC compliant) but you get the idea.

 @"^(([\w\.\-]+)@([\w\-]+)((\.(\w){2,3})+)|(No Email))$"
