I have a customer that runs different kind of campaigns but not necessarily running events. They want certain information but don't want to save this on the contact profile, i .e. they only want temporary information from their customers. In this case, the optimal way is using landing pages on their website. Currently you can't use Custom Registration Fields on Landing forms, they can only be used on Event Registration forms. To run Event Registration forms you need to connect it to an event. Is there another way around this?
