When you want to activate your email with Google Apps, just do it at google.com/a/cpanel/domain/new. Just follow the instructions in setting up your free email under your domain and then verify it. After you’ve done everything you will then be having an email with your domain. So, just check this out just in case you want to enjoy creating and having emails under your domain name. In my experience I have an email under this domain during the time of my purchased since this is under G-Apps last year. And I still am enjoying my free email even if I transferred my blogging platform into WP.
