Automatic Group based on Enrollments & Notifications - Verification

We would like to send a notification to remind new users to complete an onboarding course that they have been enrolled in, but have yet to complete. 


To create the group I was going to create an automatic group based on their enrollment status in the specific course, to meet ANY of the criteria for that specific course (so we can target the notification email):

• Enrollment Status - Not Started
• Enrollment Status - In progress

Then, send a notification to this group (which should update automatically) 14 days after they are automatically enrolled in the course and again at 30 days after they are enrolled if it’s still not completed.

**Enrollment rule already set up. 

Here’s the multi-part question:  

1. Is there an easier way to do this than setting up two separate notifications?
2. Can someone confirm that ‘Not Started’ will only apply to those users who have been enrolled in the course? ( I know this may sound dumb, but I don’t want this to go out to ALL users, only those who are enrolled in the course)
3. Does the ShortCode in the Enrollment email [first_name] show the user’s first name, or the first name of the admin who enrolled them in the course? (again, this may sound dumb but we accidentally sent 100,000+ emails to users with MY NAME in the email b/c we weren’t told that the short code field in the Course Properties Have Been Changed notification isn’t the USER’s name… )

Thank you in advance for your feedback!
