Is it possible to capture additional information when multiple tickets are sold than just the name. For example, I would like to capture all of the ticket holders email addresses for future marketing.
Not by default. But you may be able to do it with third-party plugins or woocommerce addons, if it exists.
Can you advise how additional attendee information can be captured.
This issue is mentioned on so many threads but there is no answer.
What third-party plugins are compatible. Do they actually exist??
That would need a lot of investigation to do such a consultation.
It would be better, to go ahead and create a customization request – that would be more helpful for us to help you out.
