What are the most effective tools for lead generation and collecting first-party data?

According to Neil Patel, tools and calculators are extremely effective for lead generation and first-party data collection, working better than other options. Quizzes rank second in effectiveness, while surveys also perform well. These interactive elements enable marketers to gather valuable customer information directly. Once this data is collected, it's crucial to leverage your email list to communicate with customers regularly. As Patel shares through John Reese's story, an engaged email list functions like an ATM—providing revenue on demand through strategic email campaigns.
