How to turn off email notifications ?

MockFlow sends two types of emails: 

1) System Email:  These are important application emails which cannot be turned OFF. System emails are sent less often on events like account registration, project shared with you , license purchase, subscription renewal, etc...

2) Notification Email: These emails are sent whenever collaborators of your project leave comments or make other updates

While system emails cannot be turned off as they are sent only when important activities occur, notifications emails can be opted out by following the below screenshot.
