Since ZohoMail doesn't plan to grandfather free users already using certain features, it would be good to have some foresight into what is going to removed down the pike. This will help free users plan better on their options. I ask this since I received an email that the feature to use Custom URL like "mail.yourdomain.com" is being removed for free users. When google moved G Suite to paid they grandfathered the existing free users and didn't take anything away from them.
