Check if the 'Group Recipients' option is selected in emailgtw -> Properties -> General tab
Enabling this checkbox 'Group Recipients' will send one email with multiple recipients.
Only the first group's template and subject settings will be used, since only one email is generated
You may specify multiple e-mail addresses for each profile (see Profiles section of emailgtw).
When checking the Group Recipients option, one e-mail message will be sent to all recipients. All the recipients will appear in the To line in the e-mail message.
If not checked, one e-mail will be sent to each of the recipients defined.
Ensure the correct order of profile is configured in the Recipients section in the NAS Auto-Operator profiles configured to send the email message
