In addition to assigning tasks to staff members, you can also choose a deadline for the task to be completed.
How to create deadlines for tasks
First, navigate to the Tasks tab under the Overview page within the campaign for which you wish to assign a task.
Hover over any item in your task list. A "pencil" icon and a red "X" will appear, over to the right.
Click the pencil. A grey bar will appear, which will either show the current due date assigned, or will indicate "no due date". Click the grey bar to open the "due date" option for editing.
Select the due date from the calendar, and the grey bar will update automatically. Then, click the save button for that task item.
