Task Pigeon provides an email notification when a task becomes “Due Soon” (i.e. due within 24 hours). You can however turn off due soon email notifications from the settings page in your account.
To navigate to the setting page first login to your account. You then need to click your name/profile icon in the top right hand corner.
This will open a drop down menu which will allow you to click on the settings page. Once you are on the settings page you will see the option to toggle email off for “Due Soon Alerts”.
