Yes, it is possible to create a private ticket via email in BoldDesk by using the #private command in the email body. When this command is included, the ticket created from that email will be marked as private, making it visible only to agents and hidden from the customer portal.
This feature is part of BoldDesk’s email actions functionality, which allows users to control ticket properties through specific commands in email content.
For more details, refer to the official guide: Email Actions – Update Ticket Properties via Email.
