Click-Through Rate (Email)

Email click-through rate (CTR) measures the percentage of recipients who clicked on one or more links in an email, calculated as (Unique Clicks ÷ Emails Delivered) × 100. Unlike open rate, CTR is a reliable engagement signal unaffected by image blocking. It reflects content relevance and call-to-action effectiveness. Industry benchmarks vary widely—e-commerce averages ~2–3%, while newsletters may reach 5%+.
