I have had this service for few years out of lack of time to find another mail service provider. There has NEVER been a year where I have had no issues with it. As of today I have had two days unable to login because Zoho's system will not send my verification code. Can you imagine paying for this crap?! I am locked out of my work and unproductive because of my own dependency on an undependable mail service. This does it for me though. I am DONE with them!
