Coursera will send emails to people in your programs with announcements specific to the courses they're in, like upcoming deadlines.
People in your programs can opt out of emails from Coursera using the Email Preferences section of their Account Settings page.
Coursera will not send more general emails like course recommendations. People in your programs are automatically opted out of these additional communications from Coursera. They are also automatically opted out of emails from the universities who offer the courses in your program.
