Use Business Emails Only? when you only want attendees to register with business or work email addresses. When this setting is enabled, HeySummit blocks registrations from common personal email providers such as Gmail or Hotmail and asks the attendee to enter a business email address instead.

Only use this setting if it is important for your event to collect work email addresses. Some legitimate attendees may use personal email addresses for event registration, so enabling this can reduce the number of people who are able to complete registration.
