If you are a new user and want to receive task overdue reminders via email and mobile notifications, you can enable it in profile preferences. This way you can be better informed regarding tasks which need immediate attention.
To enable this, head to profile preferences(click the arrow next to the profile name and profile status) and click ‘Preferences’. Scroll down to ‘@ Email Preference’ (Mail me everything or Mail me only important items should be enabled) and check the option ‘Email for task overdue’.
Here is a screenshot for reference.
