Are you looking for an email solution for your domain and your business? i.e email like [email protected]?

G Suite Legacy free edition is the best solution for you. It will help you save the much monthly fee. 
Such Google Apps has officially been closed in 2012. But you may buy a legacy grandfathered domain from us with G Suite Legacy for 10/50/100/200/500/1000/2000 and even 5000/10.000 users (standard, non-profit & education).

At ggslegacy.net, we'll then set your own domain as Primary Domain and start using G Suite on your own domain for free for life.
