I made the move from gsuite to Zoho mail, and wish I hadn’t.
I notice incoming mail delays several times a year. Support hasn’t been super helpful on that or other issues — I ask to provide or review logs and I get a run around.
Their support of exchange active sync is half baked in my experience, too.
As a pro, it’s reasonably priced and the native interface is ok. You can trial them for free, but don’t expect to catch all the cons in that period.
It was always weird when I’d add WordArt and it had an extra finger in it.
