How to Calculate Click-to-Open Rate (CTOR)
The Click-To-Open Rate (CTOR) is a critical email marketing metric that measures the percentage of people who clicked on a link in your email relative to the number of people who opened it. Unlike the Click-Through Rate (CTR), which compares clicks to total delivered emails, CTOR focuses purely on the performance of your email content.
The CTOR Formula
Why CTOR Matters More Than CTR
While CTR measures the overall health of your list and subject line combined, CTOR isolates the effectiveness of your email's internal elements:
- Copywriting quality
- Call-to-Action (CTA) placement and design
- Image relevance
- Offer value
- Mobile responsiveness
Example Calculation
Imagine you sent a newsletter to 10,000 subscribers.
• 2,000 people opened the email (Unique Opens).
• 200 people clicked a link inside (Unique Clicks).
Step 1: 200 ÷ 2,000 = 0.10
Step 2: 0.10 x 100 = 10%
Your CTOR is 10%.
What is a Good CTOR?
Benchmarks vary by industry, but generally:
- 8% – 10%: Average performance.
- 11% – 15%: Good performance.
- 20%+: Excellent performance (indicates highly relevant content).
