Turn off Admin Confirmation Email Messages
You may not want to receive a copy of every message that is sent to your attendees. You can turn off the confirmation email messages to your attendees by removing the recipient in the TO field of the Admin Context of each message type.
Note, this requires access to the Customizable Confirmation Emails or Customizable Tickets and Confirmation Emails, plus Check-in Tracking upgrades.
Here is a video showing how to do this:
Navigate to: Event Smart > Messages > Default Messages
Then edit the message that you want to turn off. Be sure you are editing the Admin context, then remove the recipient from the To field and save the message.
