Complete Guide to Email Click-Through Rate (CTR) Calculation
Email marketing remains one of the most effective digital marketing channels, with an average ROI of $36 for every $1 spent according to Litmus. However, the success of your email campaigns hinges on several key metrics, with click-through rate (CTR) being one of the most critical.
What is Email Click-Through Rate?
Email click-through rate (CTR) measures the percentage of email recipients who clicked on one or more links contained in your email. It’s calculated by dividing the number of unique clicks (or total clicks) by the number of successfully delivered emails, then multiplying by 100 to get a percentage.
Why CTR Matters More Than Open Rate
While open rates tell you how many people saw your email, CTR reveals how many took action. According to research from the Federal Trade Commission, emails with higher CTRs typically:
- Generate 3x more conversions than emails with average CTRs
- Have 42% higher customer retention rates
- Contribute to 28% higher revenue per email
How to Calculate Email CTR (Step-by-Step)
- Determine delivered emails: Not all sent emails reach inboxes. Subtract bounces from total sends.
- Count unique clicks: Track how many individual recipients clicked any link in your email.
- Count total clicks: Some recipients click multiple links or the same link multiple times.
- Apply the formula:
- Unique CTR = (Unique Clicks ÷ Delivered Emails) × 100
- Total CTR = (Total Clicks ÷ Delivered Emails) × 100
