Is it possible to send an email to a class that are you not enrolled in?
If so how?

Find somebody in the class who will cooperate with you and forward it. Or else, email the prof.
On the other hand, an unsolicited broadcast seems a bit like spamming.

Why can't you email through normal Mac email (not Avenue)?

It is not possible, because the purpose of avenue email is supposed to be for academic/class-related things. If you're not enrolled in a class, there is no class-related reason for you to be emailing everyone. They want to avoid spamming.

Depending on the faculty, there is a class list email that you can use. I don't know Kin so can't help. Maybe try it out using your faculty domain.

eg:

[email protected] cmaster.ca (everyone undergrads in ECE)
[email protected] ter.ca (only people in EE 2CJ4 course)

You can try using this one [email protected] which go to everyone, maybe put a title with the course name like "Course Name - Need class notes"
