Hi Friedhelm,
Thanks for reaching out!
You are correct that the customer will receive one email confirming their order and one with their actual tickets.
By default, the site admin (or a different email address that you specify) will also receive an email notification of the new order. However, the organizer listed on the event does not receive an email notification by default, but you can set this up with some custom code – you can find an example here.
We do offer full refunds within 30 days of purchase, so if you’d like to take Event Tickets Plus for a test run, feel free to do so! Please let me know if you have any additional questions or if I’ve misunderstood what you’re looking for.
Thanks,
Jennifer
