Hi,
Thanks for using our plugins. I can help out here.
If you would like to add more information to the ticket email you will have to modify the template per our themer’s guide:
https://theeventscalendar.com/knowledgebase/themers-guide/
Please create a file here called email.php:
yourtheme/tribe-events/tickets/email.php
Then add the contents of this file to it:
https://gist.github.com/jesseeproductions/a00c6542cb08d2c549bb
That will add the description, under Ticket Description in the ticket email.
If you would like to change that just edit the wording in the template.
Let me know how that works out.
Thanks
