Marketfish is an automated lead generation platform that allows advertisers to discover marketing lists, build campaigns, and monitor performance in real time. It uses data from its large list aggregator to make smarter targeting decisions and offer performance-based pricing. This solves problems advertisers face with the traditional inefficient list marketing process. Marketfish's new Customer Insights features include an ROI calculator, look-alike service to profile existing customers, and demographic reporting to analyze campaign engagement by attributes like location, demographics, and company details. This provides valuable insights into advertisers' customer segments.
