By default the TRYTN primary account holder receives email notifications for things like orders. However you can also add additional users to automatically receive a copy these emails as orders are placed. To configure this navigate to Settings > Notifications. Here you are presented with a list of additional email addresses that will receive copies of email notifications (if any) as well as the ability to add new email addresses.

Enter an email address in the New Email field and click Add. The email will appear in the Additional Emails section. Once you have repeated this for all email addresses you wish to add click Save Changes. All subsequent order emails will be sent to the primary account holder as well as all emails in this list.
