In CA, WA and other states it is against privacy regulations and subject to fines, to send the RSVP or any confirmation email w/o further confirming the person that completed the RSVP is indeed the owner of that email address. Otherwise, anyone can use this ticketing system to spam users.
I have the free version and it does not offer that option. will the paid version let me do that? asking users to login is not an option as we will be handling around 50,000 registrations per quarter to different nonprofit events.
Thanks for the help
