I just used the "Mass e-mail" feature for the first time ever last night. The page for the function says:
"Here you can e-mail a message to either all of your users or all users of a specific group having the option to receive mass e-mails enabled."
What happens when "Send to group" is set to "All users" for the Mass e-mail and users have "Administrators can e-mail me information" set to "no." Will they receive the email or not?
Basically I want to know if this is functionally the same as "opt-out" for the "Mass e-mail" feature.
