Why Is My Email CTR Low?
Common issues that hurt email click-through rates
- Poor Mobile Experience
Over 60% of emails are opened on mobile. Tiny buttons, broken layouts, or slow-loading images kill mobile CTR.
- Weak Call-to-Action
Your CTA should be clear, compelling, and visually prominent. Use action verbs like 'Get', 'Claim', or 'Download'.
- List Fatigue
Sending too frequently causes subscribers to ignore your emails. Test different cadences to find the sweet spot.
- No Segmentation
One-size-fits-all emails underperform. Segment by behavior, purchase history, or engagement level for better results.
CTR vs CTOR: Which Metric Should You Track?
Clicks ÷ DeliveredClicks ÷ OpensPro tip: Track both metrics together. Low CTR + High CTOR = subject line issue. High CTR + Low CTOR = content issue.
Email CTR & CTOR Formulas
CTR = (Clicks ÷ Sent) × 100 CTOR = (Clicks ÷ Opens) × 100 Email marketing uses two key click metrics: CTR measures clicks against total delivered emails, while CTOR measures clicks against opened emails (indicating content effectiveness).
Apple Mail Privacy Warning
Since iOS 15, Apple Mail Privacy Protection (MPP) pre-fetches email images, artificially inflating open rates. This makes CTR a more reliable metric than Open Rate for Apple Mail users. Focus on CTOR when analyzing iOS-heavy subscriber segments.

Frequently Asked Questions
What is the difference between CTR and CTOR?
CTR (Click-Through Rate) is calculated based on the total number of emails delivered (Clicks ÷ Delivered). CTOR (Click-to-Open Rate) is calculated based only on the people who opened the email (Clicks ÷ Opens). According to Campaign Monitor's research, CTOR is a better indicator of your email content's effectiveness since it isolates content performance from deliverability factors.
What is a good Email CTR?
A good email CTR is typically between 2-5%, according to Mailchimp's 2025 Email Marketing Benchmarks report. However, this varies by industry: e-commerce averages 2.6%, while hobbies/creative sectors reach 4.5%. Anything above 5% is considered excellent performance.
What is a good CTOR?
A good Click-to-Open Rate (CTOR) is generally between 10-15%. If your CTOR is below 10%, it suggests that your email content or offer wasn't compelling enough to those who opened it.
How can I improve my email CTR?
To improve email CTR: use clear and compelling CTAs, personalize your content, optimize for mobile devices, segment your audience, test different subject lines, and ensure your email design is clean with a single focused message.
Why is my CTOR high but CTR low?
A high CTOR with low CTR indicates your email content is engaging for those who open it, but your subject line or sender reputation may be preventing opens. Focus on improving your subject lines, sender name recognition, and send timing.
How does email list quality affect CTR?
List quality significantly impacts CTR. Purchased or scraped lists have extremely low engagement. Organic, permission-based subscribers who actively opted in will have 3-5x higher CTRs than cold contacts. Regular list hygiene removes inactive subscribers.
