Good evening Simone and welcome to the Events Calendar Support forum!
Thank you for reaching out to us.
We are sorry to hear that you are not receiving ticket emails.
I would love to help you with this topic.
As a first troubleshooting step, could you please provide us with your system information in a private reply ? (following the instructions found in the link)
Secondly, you should know that the tickets are only sent out once the order status is changed to Completed. Would you mind trying that ?
Let me know how that goes.
Best regards,
Geoff B.
