Definition
Email content marketing is the practice of delivering valuable, relevant, and consistent content to subscribers via email with the goal of building trust, demonstrating expertise, and ultimately driving profitable customer action. Unlike direct promotional email, content marketing focuses on providing value first and making offers second.
Email is one of the most effective content marketing channels because it delivers content directly to subscribers who have opted in to hear from you.
