What is a marketing funnel platform and do I need one?

A marketing funnel platform (ClickFunnels, Leadpages, Kartra) combines landing page builders, email sequences, payment processing, and funnel analytics to optimize conversion from lead to customer. You need one if you're running structured marketing funnels with distinct awareness/consideration/conversion stages. For most B2B SaaS companies, a proper CRM + email tool is more appropriate than a funnel platform, which is better suited for info products and e-commerce.
