When a new ticket or a reply includes an attachment, those attachments are not normally included in any of the email alerts and notifications. However, with this add-on you have access to a new tag called ATTACHMENTS. To use this tag, simply place {attachments} anywhere in the email template – generally at the bottom. All attachments will then be included in outgoing emails.
NOTE: You can see a complete list of email template tags by going to the TICKETS->SETTINGS->EMAILS tab and then clicking the HELP link in the upper right side of the screen.
