a. Initial Form of Marketing

The initial form of email marketing used in the past depended on bulk and injections that were used with generic greetings. Open and click through rates were within single digits. With the inbox becoming saturated, marketers embraced the strategy of segmentation and A/B testing to make engagement marginally better.

b. The Leap AI

Contemporary email writing AI utilises natural synthesis of language, machine learning and forecasting analytics to:

    Produce context sensitive copy that goes with brand voice
