Adding Leads to a Campaign (atEvent Hub)
Your company’s Campaigns typically target existing and prospective customers. You can associate leads collected in atEvent and assign them to campaigns that you currently have setup in your MA/CRM. The connection between atEvent and your MA/CRM will be using a Campaign ID. You will need to extract this data and copy to atEvent and later map the fields when completing the field mapping step.
