Develop a comprehensive email marketing automation strategy for our <product/service> that delivers highly personalized content throughout the customer lifecycle. Begin by segmenting our email list based on demographic data, behavioral patterns, and engagement levels. Design a series of triggered email workflows for various scenarios such as welcome series, abandoned cart recovery, post-purchase follow-ups, and re-engagement campaigns. Create dynamic content rules that automatically customise email elements (e.g., subject lines, product recommendations, offers) based on individual recipient data. Outline a strategy for progressive profiling to continually enhance personalisation over time. Propose A/B testing methodologies to optimise email elements and timing. Recommend ways to integrate email marketing with other channels for a cohesive cross-channel experience. Finally, suggest metrics and KPIs to measure the effectiveness of the email automation strategy, including engagement rates, conversion rates, and customer lifetime value impact.
