To use the Exhibitor list feature, you must include a main contact per each exhibitor profile. The reason this is required is so that your attendees can connect with exhibitors through the Exhibitor's profiles. Your exhibitors will receive an email from Whova with the leads they connect with.
You will also notice that once you've added the contact (name and email) that you will then be able to send each of these exhibitors an email from the Exhibitor Center on your dashboard. This email, sends them each a unique link that allows them to add in the information that will appear in their exhibitor profile. They will do this on a desktop version through their browser (not on the app). They can upload their own company logo, company description, add coupons/raffles/giveaways, etc.
To send this email you only need to click "Email Exhibitors" and "Send". You only need to click once to send to all exhibitors. They will each be sent their own unique link.
