No reason to reinvent the wheel here, the following post explains a regex 
approach to email validation and provides bash formatted options.

Doubt the link will die but none the less:

^(([-a-zA-Z0-9\!#\$%\&\'*+/=?^_\`{\|}~])+\.)*[-a-zA-Z0-9\!#\$%\&\'*+/=?^_\`{\|}~
]+@\w((-|\w)*\w)*\.(\w((-|\w)*\w)*\.)*\w{2,4}$
