Are you referring to when running payroll in QuickBooks Desktop? If so, there's no option in QuickBooks Desktop. However, you can check that within your company file.
You can check this article for more information about setting up payroll reminders: Set up and pay scheduled or custom (unscheduled) liabilities.
You can also refer to this article for more information about creating a customized template when sending an email from your QuickBooks to your customers and vendors: Create custom email templates in QuickBooks Desktop.
