This document compares email marketing and marketing automation. It defines email marketing as directly marketing to groups using email, while marketing automation focuses on defining, scheduling, segmenting and tracking marketing campaigns using technologies like autoresponders. Key differences are that marketing automation tailors each email for personalization, while email marketing sends the same messages to all. Marketing automation also has greater awareness of user behavior through link tracking and reporting. Integration with CRM systems is another distinguisher. Both can be effective depending on a business's needs.
