Zoho Mail doesn't enable desktop notifications by default, so you will need to visit Zoho settings to enable them.  Here's how:

  1. Login to Zoho Mail
  2. Go to Settings, and select System
  3. Turn ON notifications by using the toggle button next to Desktop Notifications.


Now, you will receive notifications about your emails on the desktop.  They will also appear in the Wavebox Mini menu under the 'Notifications' tab.
