What is the difference between Basic and Pro plans?
If you are running a smaller event, and just selling tickets - you may want to consider a Basic plan.
However if you are interested in running an event with some of the advanced features, like customizing the confirmation email content, removing Eventzilla branding on your event pages and emails, using your own domain for the event page, customizing the checkout form, and discount codes to promote your event, then you may want to consider the PRO plan.
