How to Calculate Click-Through Rate for Emails

Understanding your Email Click-Through Rate (CTR) is essential for evaluating how engaging your content is for your audience. While open rates tell you if your subject line worked, the CTR tells you if your email body content and Call to Action (CTA) were effective enough to drive action.

The Email CTR Formula

To calculate the CTR of an email campaign, you divide the number of unique clicks by the number of delivered emails, then multiply by 100 to get a percentage.

CTR = (Unique Clicks ÷ Delivered Emails) × 100

Calculation Example

Imagine you sent a newsletter to 10,000 subscribers. Out of those, 200 emails bounced, meaning 9,800 were successfully delivered. If 245 people clicked on a link within that email, your calculation would look like this:

• Unique Clicks: 245
• Delivered Emails: 9,800
• Math: (245 ÷ 9,800) = 0.025
• Result: 0.025 × 100 = 2.5% CTR

What is a "Good" Email CTR?

Average email click-through rates vary significantly by industry, but generally, a 2% to 5% CTR is considered healthy. If your CTR is below 1%, you may need to look at your email design, the relevance of your offers, or the clarity of your buttons.

Ways to Improve Your Email CTR

• Use a single, clear CTA: Don't confuse readers with too many choices.
• Personalization: Segment your list to ensure the content is relevant to the recipient.
• Mobile Optimization: Ensure your buttons are large enough to be tapped on a smartphone screen.
• A/B Testing: Test different button colors, copy, and placements to see what resonates best.
