Zoho Mail App

Hi, I have downloaded the app for my iPhone 6, the problem I have is no notifications when an email arrives. If I receive an email to the zoho email address I am notified but receiving one to my work email gives no notification so I am not aware of any emails until I open the app. I did notice under settings it only shows one folder (the zoho mail address) and not my work one. Is there anyway of allowing notifications for the company email address? Kind regards Phil
