If a school sends out an email, it needs to send it out to multiple groups at the same time. Your module only allows us to send to ONE group at a time. Ex: If we want to send out an email to Band Boosters and Athletic Boosters, we have to send out two emails. The administrator should be able to select whatever groups the email is to go out to at the time when the email is created. One email to multiple groups feature is missing.
