Note: You can enable enrollment emails for the portal and then disable them for individual courses. However, you can't disable enrollment emails for the portal and then enable them for individual courses. You can disable course enrollment email at the portal level, and still use other course-level reminders.
The setting for this feature applies to the whole portal, so is part of portal settings.
The following screenshot shows Email Settings, including Disable enrollment emails.

By default, the application sends an email to learners about new enrollments. You can disable enrollment emails for individual courses if required.
Enrollment reminders notify users that they have not yet completed, passed, or failed the course. You set the reminders a number of days after enrollment, and can send up to 4 reminders.
Tip: If you don't need all the reminders, leave the later fields blank.The following screenshot shows a sample setup of enrollment reminders for 3, 7, 14, and 28 days after the enrollment.

Ideally, you set up reminders before enrolling learners in a course.
If you add enrollment reminders after enrolling learners, learners in Not Started or In Progress status still get reminders, after you turn them on. Safety Made Simple checks when you enrolled the learner and compares it to the reminder settings, and sends the "catch up" reminders once a day.
Example:
You enrolled learners on a course 20 days ago.
Today you set up enrollment reminders for the course, as shown in the previous screenshot: at 3, 7, 14, and 28 days after enrollment.
Safety Made Simple compares the learners' enrollment date (20 days ago), and sets up 1 reminder to "catch up", for any learners' enrollments in Not Started or In Progress status.
Safety Made Simple runs the 4th reminder at day 28,
as scheduled.
Note: you need to set due dates and valid periods, before due date notifications become available in the course Notifications. The automated reminders for learners, based on the course Due Dates, have several options:
The following screenshot shows a sample setup of due date reminders for days leading up to the due date, and reminders after the due date.

Set or disable notifications to tell learners they have completed a course, at the course level.
Tip: If there is a certificate assigned to the course at the time the learner completes the course, Safety Made Simple sends the certificate with the completion notification, as a PDF.The following screenshot shows Completion Notifications options.

Add a banner to your course which the app includes in your custom email templates.
