Within Teamwork.com, reminders can be set on individual tasks in a task template.
While adding or editing a task
in the template, select the Reminders option from the More dropdown and select Add Reminder.

A due date is required to be set on the task before
reminders can be created. If one is not already set, you will be prompted to do so.

In the Add Reminder modal, you can
select users to receive the reminder, set a date and time for the reminder to be sent, choose a
reminder type, and add a custom
message.

When choosing how to set the
reminder, you can select a predefined option or set it to be relative to the task's
due date.

When using the relative option, you can set a custom
number of days and choose whether it should be
sent before or after the task's due
date.

At the bottom of the modal, you can set a time and reminder type as well as include a custom message.

Click Add This Reminder to save the reminder to the task.
