Access the Reminders feature by clicking on Settings tab --> Reminders.
Reminders can be set up to be emailed to you as a task list. This feature can be found by clicking on Reminders under the Settings section.
You can establish a reminder to be sent to you on a certain date as well as on a recurring basis. For instance, if you want to send out invoices every 2 weeks, you can setup a reminder to email you every 2 weeks with that information.
If you have more than one reminder for any day, they will be organized in one email.
