Hi Vanessa,
Thanks for contacting us — though I’m sorry to hear things are not working quite as expected.
I’m curious: if you set up a ‘regular’ product (ie, not a ticket) for testing purposes and run through the purchase process, are the relevant order emails sent? What I’m basically wondering is whether this is an issue with Event Tickets/Event Tickets Plus or something that happens more generally within your WooCommerce setup.
In that vein, if you visit WooCommerce → Settings → Emails can you confirm that the relevant emails are in fact currently enabled?
Thanks!
