What do you mean by “the email link” is not working?
Please provide a link to your site.
When I go to the demo page for your theme, http://templatesnext.org/imax/, the email address in the header is not a link, so I can only assume that’s how it’s supposed to work.
I don’t see a support link there, so please look for a support link on the site from which you bought this theme so you can get in contact with the developers.

I recommend asking in this theme’s dedicated support sub-forum for better results so its developers and users can help you with this:
