This document discusses four approaches that email programs can take to incorporate content marketing:
1) Foundational - Regular, predictable communications to maintain relationships with subscribers across a range of topics.
2) Educational - "Lead nurturing" content like tutorials and articles to move prospects through consideration phases.
3) Engaging - Entertaining content like games and contests to build interaction and reward subscribers.
4) Personalized - Highly segmented, triggered messages customized for individual subscribers.
Taking a variety of approaches keeps subscribers engaged without constant promotions and conditions them to interact over time.
