Are you looking for email hosting for your domain? i.e email like user@yourdomain.com?
Google Apps legacy version is the best solution for you. It will help you save on much monthly fee.
Such Google Apps has officially been closed in 2012. But you may buy a legacy grandfathered domain from us with Google Apps – free for 10/25/100 and even 10.000 users (standard, non-profit & education).
But this never stopped geeks to find a way around to get a Google Apps legacy or G Suite legacy account. And the golden days are back again. After spending quite a lot of money and time at last I’ve figured out a new loophole in Google’s system using which now we can again swap our primary domain as well as add the secondary domain (max 2 including existing secondary domain, if any) as we want. Besides, at http://googleappslegacy.com, we provide G Suite legacy / Google Apps legacy with your domain as primary. We’ll then set your own domain as Primary Domain and start using G Suite on your own domain for free for life.
