I thought Zoho mail is the best alternative for Gmail. Everyone, please hold on to the thought, it is not. 

I HAVE NO IDEA, HOW MANY OF MY EMAIL RECIPIENT NOT RECEIVED my emails. 

Recently found out that, any of the mails which I have sent, show it is sent. But it is not actually sending to the recipient.

Please do not use zoho mail for paramount works. 

I am moving to Gmail.
