email open 비율 계산기에 대한 도구입니다.
Email Open Rate is the percentage of delivered emails that were opened by recipients. The formula is: Open Rate = (Opens / Emails Delivered) × 100. For example, if you sent 5,000 emails and 1,250 were opened, your open rate is 25%. Note: open rate is calculated against emails delivered, not total sent (bounces are excluded).
A good open rate varies by industry. Average across all industries is 21–25%. Retail/e-commerce typically sees 15–20%, SaaS/tech 20–25%, finance/banking 25–30%, healthcare 23–28%, and non-profits often achieve 25–35%. Your own historical performance is the best benchmark.
