Hi there,
Thanks for reaching out.
Unfortunately, we cannot provide plugin support here on the Pre Sales forum. If you have a license for one of our premium plugins, you can log in with the email connected to your license, and request help in the appropriate plugin forum.
The ticket emails should include more than just a barcode, and it is also possible to customize the email message with a bit of code. This is something we can help you with in the Premium Support Forums.
If you do not have a premium plugin license, you can reach out for help on the WordPress.org support forums.

Good luck!
Thanks,
Sky
