Introduction

Email marketing remains one of the highest-ROI digital marketing channels, but success depends on measuring the right performance indicators. Looking only at subscriber counts or total emails sent provides an incomplete picture. Modern marketers should monitor engagement, conversions, deliverability, customer lifetime value, and revenue attribution to understand how campaigns contribute to business growth. When combined with SEO, AEO, GEO, and AI Search Optimization, email marketing becomes an essential component of a sustainable digital strategy.
