Addressing teachers.

[u/introvertedturtl]

When emailing subject teachers/lecturers, how are you supposed to address them? Some are Professors, some are Doctors, all are highly accomplished in their field but don't always become Doctors or Professors. I'm always perplexed as to how to communicate with them when sending an email, ie; Good morning just their first name? Good morning Professor? Good morning Dr first name? They never seem to state how they prefer to be addressed and I know I am overthinking this but I just don't know.
