Just switched over my Google hosted domains to this. I really only need email, so GSuite is overkill. Why does my throw away email address need a youtube/calendar/google+ account...... I actually originally switched from my old gmail address to my GApps email, but Google ruined it by making GApp accounts inferior. You can't do tons of stuff (Family Library is just 1 example), so I switched back. I use my gmail account as a webclient for my other accounts (pop/smtp). I got Google apps when it launched and was a great free option. Now they're removed free accounts, and even on the grandfathered free accounts, they don't let you add new domains anymore... I really just have 1 important account, and unimportant ones for hobby domains, so this is a great option for me. I considered PO Box for my important account, but for now, I'll just try this for all my domains. I really like the simplicity. I sent some test emails: Google and my work's exchange correctly get the email. outlook.com flagged as spam. I only have 2 concerns. 1, they need 2FA ASAP (which they've acknowledged), and 2, how long will these guys be around. How many employees are there, how much investment. It would suck if 12 months from now they shut down. It would be a scramble to move something as important as email. Rather than shutdown, most companies in these types of businesses up the price, remove features from the cheaper plans etc...there's no promise of price lock-in here, but since that's their market, I suspect they're aware of the effect a price increase might have.
