Lenoxsoft currently uses a manual sales engagement process where assigned users manually add leads to lists based on a lead status value of "New". The Sales Manager wishes to develop a Sales Engagement Program that streamlines this process and has the following requirements: - Only leads with a status of "New" can be added to the Program. A lead with a status of "In Progress" CANNOT be added. - Assigned users should be notified when a lead has opened an email. Based on the above requirements, which is the best way to segment prospects for Lenoxsoft's Sales Engagement Program?
