I may be wrong, but these functions are available in the pro version.
Hello @justvimbing,
1. Students can be manually enrolled and removed from enrollments after enabling enrollments addon.
2. After a student registers Tutor LMS sends email notification to admin if you have email addon enabled and the relevant option selected. After student enrolls in a course Tutor sends email notification to student which mentions the course url for which he/she enrolled. Tutor LMS sends altogether 31 emails to students, instructors and admin for various email events as shown in this image
