      return if @institution.blank? || school_changed?

      emails = recipients

      if emails.any?
        StatsD.increment("#{stats_key}.success")
        SchoolCertifyingOfficialsMailer.build(@claim.open_struct_form, emails, nil).deliver_now
        StemApplicantScoMailer.build(@claim.open_struct_form, nil).deliver_now
        @claim.email_sent(true)
      else
