Email Marketing Metrics Explained: Why Tracking Performance Matters

The growing popularity of email marketing metrics explained comes from businesses realizing that successful email marketing depends on continuous improvement. By monitoring important performance indicators, marketers can understand what subscribers enjoy and what needs improvement.
