Hey Jonas,
Thanks for reaching out!
At this time the only way to make physical tickets would be to literally print out the emails that are sent to users.
You can customize the emails themselves quite extensively, as described in detail in this themer’s guide → https://theeventscalendar.com/knowledgebase/themers-guide/, and this would require custom coding and styling.
I’m sorry that this is the only method available at this time 🙁
Let me know if this information is useful and if there’s anything else I can help with.
Thank you,
George
