Is there a due date reminder functionality?
At a time chosen by yourself, you'll get an email notification of all your tasks due today (if an AM hour is chosen) or due on the next day (if a PM hour is selected).
The email will name due dates for tasks that were assigned to you or created by you and kept unassigned, so - by assumption - meant for you.
To manage your reminder email preferences, please go to My Profile, available under your name displayed in the top right corner of the dashboard view (all boards names). On the Edit my details page, choose the time of the email arrival and save changes. If you're not sure how to use due dates functionality with Kanban Tool, please visit this page.
Note: If you don't want to receive these emails, simply select "Never" from the hour selection dropdown.
Kanban Tool Enterprise plan users can create own rules, for when due date notifications are emailed to them.
To create such an automation for your board, go to board Settings - Process Automation and type in the conditions for when emails should be sent.
Feel free to base it on the example below (click to view larger image):
