Click-Through Rate
Click-through rate (CTR) is the percentage of email recipients who clicked one or more links in your email campaign. It measures how compelling your content and call-to-action are.
(Total Unique Clicks / Total Delivered) × 100Definition
Click-through rate (CTR) measures the percentage of delivered emails that received at least one click. It is widely considered the most reliable engagement metric because clicking requires intentional action — unlike opening, which can be passively tracked by image loading.
CTR tells you whether your email content, messaging, and call-to-action resonated with your audience. A high open rate with a low CTR usually means your subject line worked but your content did not deliver on the promise.
Formula
Click-through rate is calculated using unique clicks rather than total clicks to avoid counting the same person multiple times.
CTR = (Unique Clicks / Delivered Emails) × 100
| Variable | Description |
|---|---|
| Unique Clicks | Number of individual recipients who clicked at least one link |
| Delivered Emails | Total emails sent minus bounces |
Average Benchmark
CTR benchmarks vary widely by industry and email type.
| Industry | Average CTR |
|---|---|
| Agriculture | 3.2% |
| Ecommerce | 2.8% |
| Education | 4.1% |
| Finance | 2.5% |
| Healthcare | 3.0% |
| Media & Publishing | 4.5% |
| Real Estate | 3.4% |
| SaaS & Technology | 2.9% |
| Travel & Hospitality | 2.1% |
| Nonprofit | 3.8% |
Overall average click-through rate across all industries is 2.5% to 3.5%. Transactional emails (order confirmations, password resets) often have much higher CTRs of 10% or more.
How to Improve CTR
- Write clear calls-to-action: Use action-oriented button text (e.g. "Get Your Free Report" instead of "Click Here"). Make the CTA stand out visually.
- Segment your content: Deliver relevant content to specific audience segments. Relevance drives clicks.
- Keep emails focused: One clear goal per email performs better than trying to promote multiple things at once.
- Test your links: Experiment with button placement, link text, colour, size, and number of links per email.
- Use a strong value proposition: Tell recipients exactly what they will get by clicking. Benefits drive action.
- Optimise for mobile: More than half of all email opens happen on mobile devices. Ensure buttons and links are easy to tap.
Example Calculation
If you send a campaign to 5,000 subscribers, 80 emails bounce, and 140 unique clicks are tracked:
Delivered Emails = 5,000 - 80 = 4,920
CTR = (140 / 4,920) × 100 = 2.85%
This CTR of 2.85% is close to the cross-industry average and would be considered a solid result.

Frequently Asked Questions
What is a good click-through rate for email?
A good email CTR is between 2.5% and 4% for most industries. Higher rates are common for transactional emails (10-15%) and targeted segments. Lower rates are normal for broadcast-style emails sent to large, unsegmented lists.
What is the difference between CTR and click-to-open rate?
CTR measures clicks divided by delivered emails. Click-to-open rate (CTOR) measures clicks divided by opens. CTOR tells you how engaging your content is for people who already opened, while CTR measures overall campaign engagement including deliverability and subject line effectiveness.
How can I increase CTR without misleading recipients?
Focus on relevance and value. Segment your audience based on behaviour, preferences, or demographics. Personalise content to each segment. Write honest subject lines that accurately reflect what is inside the email. Align the CTA with the recipient's stage in their customer journey.
