Worked Step-by-Step Examples

Example 1: E-Commerce Promotional Email Campaign

"Sent 50,000 emails, 1,000 bounced (49,000 delivered), 12,000 opens, 1,800 clicks, 150 sales. Campaign cost $500, revenue generated $4,500. Find rates and ROI."

Steps:

Open Rate: (12,000 ÷ 49,000) × 100 = 24.49%.
Click-Through Rate (CTR): (1,800 ÷ 49,000) × 100 = 3.67%.
Click-to-Open Rate (CTOR): (1,800 ÷ 12,000) × 100 = 15.00%.
Conversion Rate: (150 ÷ 49,000) × 100 = 0.31%.
Net Profit: $4,500 - $500 = $4,000.
Campaign ROI: ($4,000 ÷ $500) × 100 = +800.00%.

Result: Open Rate = 24.49% | CTR = 3.67% | CTOR = 15.00% | Net Profit = $4,000 (+800% ROI)
