    default from: Rails.application.secrets.mailer_username

    def test_email(user)
        @user = user
        mail to: user.email if user.email
    end

    def submitted_ballot_to_user(submitter, user, ballot)
        @round = ballot.round
        @submitter = submitter
        @user = user
        @ballot = ballot
        mail(to: user.email, reply_to: 'connect@nuscomputing.com', subject: '[Locker Ballot] Ballot Received') if user.email
    end

    def submitted_ballot_to_bot(submitter, user, ballot)
        @round = ballot.round
        @submitter = submitter
        @user = user
        @ballot = ballot
        mail(to: Rails.application.secrets.locker_mail_to, reply_to: 'connect@nuscomputing.com', subject: '[Locker Ballot] Ballot Received') if user.email
