Manual lists require you to hand-pick the companies you'd like to add. That is why manual lists are a better option if you already know which businesses belong in a certain list (i.e. you have fixed suppliers, recurrent customers or a set of companies that are prospects).
Intelligent lists choose and add companies for you, based on criteria you select beforehand. This criteria includes: Industry (if you are interested in companies from a certain industry), Country, the Products and Services they offer, Business Rating and Company Size.
Once the list is created, you can perform any of these mass actions: Send business introduction, Ask for a quote, Ask for a review. For more information about interacting with contacts/connections, click here.
